Family mediation is a course of action in which divorced or divided partners function in the direction of obtaining a resolution of a dispute among them. This dispute is usually in relation to kids, funds of assets. This course of action is a additional convenient way to settle disputes as it normally takes position outside the house the courtroom. The largest change concerning family members mediation and courtroom proceedings is that a solitary individual will work for both of those events so that there is no partiality.
This method is not restricted to disputes among the divorces or divided partners. This system can also be employed to remedy disputes between mother and father and little ones, kin and elders and also in conditions of living preparations and homelessness following divorce.
There is also no restriction on what can be talked about through the approach as effectively. A little something as trivial as who will get to retain the puppy just after separation can also be talked over for the duration of this system.
Even though relatives mediation is not legally binding, it is a mutual agreement in between both functions that would like to settle their dispute with out acquiring to go to court docket. Here, both of those get-togethers concur on a resolution that they believe that would provide their finest passions. However, this agreement can be manufactured authorized by receiving a solicitor to turn it into a authorized document and then possessing a judge agree to the settlement designed by both get-togethers.
Worth and Advantages of Loved ones Mediation:
A single of the most important positive aspects of opting for this procedure fairly than court docket cases is that this kind of procedures removes the need to have of extended court proceedings, waiting for a court docket day and then once again waiting around for the closing verdict. The period of this procedure depends on the topic and complexity of the dispute. Just about every session lasts for optimum an hour and a summary is drawn generally in 6 these periods.
Moreover, resolution furnished in the course of relatives mediation performs for both equally events even though court rulings may be favourable to only a single get together. This proves to be beneficial for each get-togethers and they can decide the consequence of the approach on their own.
Given that the mediator is effective for the two get-togethers, it eradicates the likelihood of any partial conclusion or resolution. Also, given that the mediator is not a attorney, both get-togethers can rest guarantee that they’re going to receive good support with no lawful tips. This sort of mediators have seem awareness about divorce, spouse and children rules, separation, and so forth. and that’s why are able of offering appropriate methods to all linked disputes.
A different great edge of relatives mediation is that it is totally private, barring a couple of exceptions. Only when a youngster is assumed to be underneath a treat of felony activities is the settlement of confidentiality null and void. In circumstance this method fails to come up with a solution and the dispute has to be taken to court, any and every thing reported through family members mediation can only be revealed in court right after authorization is granted by both equally events.
Family mediation also cuts down the value of resolving disputes among divorced or divided couples. It also lowers stress and raises conversation among both functions, foremost to lesser possibilities of conflict.
The moment an oasis of peace and stability in Africa, my wonderful house area of Southern Cameroons is at the moment going by way of excruciating pains, seemingly worse than the Rwandan genocide of 1994: our men and women are really being exterminated like cockroaches. Virtually two several years have gone by and, I am certain, the UN and AU have not demonstrated any authentic dedication to mediate in this menacing predicament. It is nicely known that France is pulling the strings to maintain our nation, total of rich human and natural means, captive.
In the current situations, it is imprudent for Grand Masters to parade the corridors of the Unity palace, and dine with, and confer accolades on, a president whose dormancy is suspicious a man who, considering that the introduction of the current crisis, has refused to shear the sheep. This disaster that has steadily degenerated to a civil war is no longer an inner affair. It is fairly a worldwide menace to peace and balance due to the fact Cameroonian patriots all in excess of the globe and Africans of very good will are affected. It is no more time an inner affair since the authorities has violated the universal declaration of human legal rights in all facets.
What ought to we do? There is urgent will need for cease-fire from each sides. I vehemently condemn all armed robbers and bandits who are getting gain of the circumstance to loot and harass peaceful civilians. A tranquil resolution can only be doable with the mediation of a third get together mainly because the persons of Southern Cameroons have misplaced assurance completely in the Biya regime. Looking at the aloofness of AU and UN, the Usa stands in the place to mediate at this time. Notably, the situation of Southern Cameroons has been a subject matter of dialogue at Capitol Hill with adequate proof of untold human legal rights abuses and the subjugation of the people of Southern Cameroons. As the crisis worsens by the working day, can the Overseas Affairs Committee of the US Congress revisit the case of Southern Cameroons? Sincerely, can my friends in the US recommend on what else we can do to persuade the US to action into this bloody disaster? Are the folks of Southern Cameroons a lot less human than the men and women of Libya, North Korea or Syria? Please aid us, our people today are perishing!
Permit us pray! God is not useless. He sits on the throne, and in the finish He will be King and decide but before the close arrives, we must commit ourselves listed here and now to get the job done for justice, peace, and equality.

The coronary heart of training is the student’s finding out. The duty of the librarian is to establish awareness so that mastering will become much more lastingly significant, far more permanently meaningful and far more personally satisfying. Potentially, significantly of what the college students master will have on out or grow to be obsolete. But info competencies figured out in libraries will carry on to be useful indefinitely or for as very long as they are needed (Mangay, 2004).
The faculty/faculty library is a critical spouse in awareness administration and should really share with the university/higher education their responsibility to systematically style and design, carry out, and evaluate the total course of action of discovering and educating (Herring, 1982). In which situation, the library assumes the function of mediator in between pupils/pupils and learning means, and in between instructors/lecturers and educational methods. The library contributes to a significant, satisfying and demanding education and learning, if instantly concerned (Mangay, 2004).
The university/higher education library should be observed as an integral aspect of the school/college or university organization and not as an orphanage. Its advancement are unable to be isolated from improvement in instruction since it is a section of the schooling system. The library is one of a kind in that its consumers are section of its instruction, obtaining skills in the powerful use of data to fulfill selected mastering objectives. The library is not basically a assistance to the curriculum but an lively aspect of the curriculum.
Instruction typically is going from standard class training of limited subject matter/modules, towards a lot more unique operate, group discovering, task function, research and making raising use of non-e book as perfectly as guide means. The disappearance of streaming in the college curriculum plays a critical position in the search for solutions or resources that will cope with the wonderful wide variety in the mastering capabilities of pupils/students.
The traditional ‘chalk and talk’ solution of instructor/lecturer centred education and learning has been modified. Academics/lecturers now spend their time to introduce pupils/pupils to topics and clarify concepts and procedures in a lecturer-style situation. Pupils/college students are expected to study for on their own and by them selves and where probable as their own tempo. We continue on to see the gradual growth of the use of the ‘newer media’ alongside the ‘older print’ medium (Mangay, 2004).
College/college libraries provide a finding out atmosphere inside which the pupil/college student can study and practice the approaches of enquiring and study. Their collections express expected prerequisites of all educating models and exclusive pursuits of the school/faculty, and in addition, spend individual interest to the individual cultural and recreational passions of younger individuals by themselves, so that looking through and enquiring develop into natural patterns of daily life.
Libraries are now getting into a new phase of progress in the info age. New educational developments have strengthened the function and significance of faculty/librarians. They have the task of satisfying the purely natural position of college/faculty libraries as a centre for mastering and the exploitation of all readily available approaches of interaction. The library is a conversation centre. Its determination and issue for the encouragement of examining and enrichment of the individual’s imaginative and innovative lifestyle stays undiminished (Taylor, 1980).
It is the obligation of the librarians to be certain that clientele create the talent to find, use, examine and retrieve resources according to the clientele’s own felt want and needs. He ought to give reference and assistance solutions when the clientele’s competencies are not sufficient to the lookup difficulty at hand (Grass and Klentz, 1999). Librarians are frequently viewed as companies of methods, instead than co-instructors who share common ambitions. The librarian is an educator, custodian, organizer and disseminator of knowledge. The library for that reason, enables the university student to investigate context further than curriculum.
Powerful library use will increase library-consciousness of young men and women renovate non-users and enthusiastic college students to grow to be lifelong audience and learners. Library-consciousness will also modify the view of college students who believe his/her function in the library is only to examine lecture notes or charge cellular telephones devoid of the capacity to make analysis for assignments, challenge-crafting or other academic assessments. The library allows people to develop lifelong literacies. It can help to raise unique student attempts and attainment makes a new glance at the use of information, and it is a stimulus for the tutorial local community (lecturers, team, students, researchers).
Lastly, the library must be recognised and used by other specialist colleagues in the studying business (Lance and Loertsher, 2001). It provides professional clientele by the assets presented, consequently facilitating richly-enhanced lecture notes fruitful to students’ studying, job composing, term papers, assignments and of study course, examination. Improved solution will be taken on modules taught and ‘notes-making’. This stimulates partnership between lecturers and the librarian. The operate of the librarian is of substantial-high quality and he/she makes useful contribution to the tutorial neighborhood (Grass and Klentz, 1999).

If you are a to start with-time landlord, you ought to be aware of the great importance of rental applications. These purposes, which you can get from lawyers, are loaded out by future tenants and involve all of their pertinent money information and facts. Getting this info from possible tenants will aid you make an knowledgeable determination on whom to accept. In this article are some issues you may possibly have about rental purposes and tenants:
What Must Be Integrated on a Rental Application?
Most lawyers will suggest you to have possible tenants fill out a entire rental application. This will give you an prospect to master extra about your prospective tenant’s payment historical past. On the software, you have to have to involve the tenant’s employment facts and income, a credit history record, social stability, driver’s license quantities, and any heritage of bankruptcy. You really should also question if they have experienced any earlier evictions, as effectively as need a listing of references from their past rentals. This will permit you to defend your investment assets from any individual who has a negative historical past of not having to pay rent on time or at all.
Is a Rental Software Required?
While the law does not need rental apps, having candidates full just one is a genuinely fantastic practice as a landlord. These programs are created to accumulate a wonderful offer of information and facts about potential tenants, info that you can use to secure yourself if a person of your candidates turns into angry that he or she wasn’t selected. If that particular person attempts to sue you simply because they claimed you discriminated in opposition to them, you will have a reliable report that will prove you centered your assortment on fiscal instances only, which can aid you win a lawsuit.
Can Landlords Refuse to Hire to Sure Tenants?
By legislation, landlords are not permitted to discriminate from rental candidates based on ethnicity, religion, or age. Nonetheless, in most states, landlords are authorized to question applicants to provide proof of citizenship. You can do this in a range of strategies. They can give a copy of their passport, a naturalization certification, or a momentary visa. Retain in brain that if you are heading to request for this details from a person applicant, you need to request it of all of them. You will not want to surface discriminatory from probable tenants. Also, try to remember that in some states you are not allowed to inquire for immigration position on any of your tenants, like New York and California.
Picking out a tenant for your rental home need to generally be taken very critically. Be absolutely sure that you do not discriminate in any way. In simple fact, attorneys usually advise landlords to offer a abide by-up call or letter to candidates who were being not selected, furnishing a thorough rationalization. Also, normally try to remember to hold on to all information and facts presented to you to have in the occasion an applicant sues you.

Service Oriented Architecture: Triangle of Truth
The triangle of truth is a simple way to look at the important architectural constructs that make up a service oriented architecture. As you begin thinking about what is needed to build a service oriented architecture, the triad that makes up the triangle of truth quickly emerges. Specifically, there needs to be a way to represent the data that is exchanged between services, there must be a mechanism for invoking services, and there should be a way to compose services into a larger integrated business application.
Today there are many different programming models for supporting each construct in the triangle of truth. This situation presents developers with the challenge of not only needing to solve a particular business problem, but they are also faced with choosing and understanding the appropriate implementation technology. One of the important goals of the WebSphere Process Server v6 SOA solution is to mitigate these complexities by converging the various programming models used for implementing service oriented business applications into a simplified programming model.
This presentation focuses specifically on the Service Component Architecture (SCA) introduced in WebSphere Process Server v6 as the service oriented component model for defining and invoking business services. In addition to the important role SCA plays in providing an invocation model for the SOA solution in WebSphere Process Server v6, you will also learn in this presentation that it also plays a role in composing business services into composite business applications.
Whenever you are beginning to learn a new technology or programming model, it is often useful to look at the pieces that compose the overall architecture of that technology. This slide lists some of the important features of SCA that you should be aware of as you begin learning about SCA.
First, the Service Component Definition Language(SCDL) provides the basis of SCA. SCDL is an XML based definition language, and is used to define all SCA artifacts in a project. The WebSphere Integration Developer V6.0 tools support of SCA takes care of generating the appropriate SCDL definitions when building an SCA-based applications, however a basic familiarity with SCDL can certainly help understanding the overall architecture and debugging applications.
The next important part of SCA to understand is different is the different types of artifacts that can be defined using SCDL. The various artifact types that exists in SCA were designed to support some of the basic requirements of this service oriented architecture. To start, the most basic building block in SCA is the service component definition. Once a service component is defined, it is important to have a mechanism for making that service available to clients inside and outside of the current.
Service Component Overview:
This is a common concept which will be familiar to those from a WPS background. SCA was first introduced in the concept of WPS V6 as an architecture and implementation to support the enablement of a Service Oriented Architecture approach to process Integration. SCA underpins the programming model in WPS and is also fundamental to WESB. Everything is a Service And a Component And has an interface which describes it.
SCA separates component interface from their implementation. The implementation of an SCA component may change without affecting the interface. It is possible for example, to replace the implementation of component, say with a Web Service invocation rather than invocation through an adapter. We invoke components, so one can regard SCA as perhaps as invocation model as much as anything.
This situation is kind of represented on this next foil – we can see that a Service Component provides an invocable Service Instance. In order to provide that, it must have an Implementation, an Interface, and Configuration properties. A critical point here is that the Implementation can be any of the programming constructs that we provide in WPS. So it could be a BSM, BPEL Process, Map, Adapter, POJO.
Interface can be of two types-Interfaces that this module exposes for consumption by others, and Interfaces exposed by other modules that we want to consume. This latter type of interface consumption is called a reference. We should also note that the interface can be described using either Java interfaces or WSDL. But if there are multiple interfaces specified then you cannot mix WSDL with Java. For reference type you do not have that restriction.
Service Module: Overview
Here we have got our Service Module, which we know is the SCA unit of packaging and deployment. We can see that this particular Module contains 2 Service Components- each containing an implementation, Interface and references where appropriate. This second Service Component does not contain a reference because it does not invoke any external Service.
Now in the Service Module we can see that we have a number of additional things, which are related to incoming and outgoing Interfaces at the Module Level. Remember that an Interface and reference describe incoming and outgoing interface at the Service Component level. Well we have a similar notation at the Service Module level, referred to as imports, Exports and Standalone references.
An Export is how the Service Module exposes its interface to the outside world for consumption by another Service Component within a different Service Module. A Standalone Reference is how the Service Module exposes its interfaces for consumption using a non-SCA client invocation mechanism. Clients using this invocation mode are either Other SCA components within the same SCA module, or non SCA clients such as a JSP. An Import is how a Service Component invokes an external Service. The relationship or potential invocation path between these artefacts is represented by wires.
SCA Basics and terminology
SCA is a runtime that facilitates the abstraction of a component’s implementation
SCA separates infrastructure from Business Logic
Provide a programming model for invocation
Support a variety of the invocation models
Provide the runtime infrastructure suited for application consumption
Universal model for Business Services, Publish or operate on business data. Service Data Objects (SDO) provides the universal model for “business data”. Components run on a SCA enabled run-time, Java interfaces (j-typed), WSDL port types9w-typed). Arguments and return are described using SDO’s, Java classes, or simple Java types. SCA focus on business purpose.
Service data Objects and Business Objects
As introduced already in the triangle of truth, business objects play an important role in the WebSphere Process Server v6 SOA solution as the data abstraction. This is indeed an important goal of the business object framework, but in addition to this, the business object framework also provides some other important functions. Specifically, the business object framework was developed to provide functional capabilities similar to the business object construct found in WebSphere Interchange Server(ICS). The set of capabilities that have been adopted to support ICS style business object functions, are needed to provide a way to help developers mitigate the complexities related to developing applications that work with federated and disparate business data as is commonly the case with integrated enterprise applications.
SCA provides the ability for services to be called synchronously or asynchronously.
An asynchronous invocation model is also provided with the following semantics
One Way -Fire and Forget
Deferred Response-In this model the client makes a request, but does not bloc, but at some later point in time goes back and asks for the response. In this form of invocation takes a second parameter which specifies whether the invocation behaves when the response is not immediately available. (invoke Async() returns a ticket that identifies the invocation. invokeResponse() passes a ticket back in that is used to get the response that corresponds to the invocation identified by the ticket)
The semantics of the synchronous vs asynchronous invocations differ as summarized here. So synchronous invocations are pass-by-reference, whereas asynchronous invocations are pass-by-value. Note also that if you want type-safety you’ve got to be using Java interfaces definitions. However there is tooling to allow you to generate Java interfaces from WSDL definitions. Synchronous calls outside the JVM are pass-by-value invocations. We could use an extra column in this chart.
Enterprises service bus reference architecture
We are going to introduce all these elements later in the presentation. Lets look at the scope of WSEB and all the things the customer gets in the box. The product is named ESB not Enterprise Service Bus. The naming reflects the industry mindset. It allows an ESB to be built which brokers service requests and responses. It is primarily a Web Services focused platform specifically to support the service interactions that take place within a SOA. ESB is built on AS (ND) and therefore fundamentally a J2EE platform. It leverages and shares technology introduced with WAS V6 and WPS. Use of the additional products and capabilities shown ( for example, TAM) are optional.
Introduces the concept of “mediations” as a term for message (broker) processing. Service invocations are Service messages within the ESB. A new version of WID is released which supports the development of mediation flows. The ESB supports mediation flows and primitives with which to build mediation processing. Support for basic ESB processing is supplied. WESB leverages the messaging support delivered in WAS V6 (SIB) using the JMS 1.1 provider and the MQLink to interoperate with an MQ QM. The WS support again leverages base AS support SOAP/HTTP and SOAP/JMS as protocols and the various WS-* capability. SCA (define) is the programming model which is the technology first surfaced, and shared with WPS. It is the foundation for the composition of mediation and process logic. SDO (define) allows for the logical representation of business data. The SMO (define) is an extension of an SDO message which is the service message which flows through the ESB. XMS clients (C++ and .Net). JAX/RPC client invocations supported via WS C/C++ client. Connectivity to other endpoints is achieved using the WBI Adapters (either the original adapters or the variants which support JCA 1.5).
In a loosely coupled SOA architecture, Service requestors and providers connect with each other through an Enterprise Service Bus. Loosely coupled Services provide more flexibility and ability to introduce mediations and QOS that can then be applied uniformly to the services connecting through the bus. Mediation services intercept and modify messages that are passed between existing services(providers) and clients (requesters) that want to use those services. Mediation services are implemented using mediation modules that contain mediations flows. WebSphere ESB and Process Server provide the ESB capability through the use of Mediation Module deployed in the server. Mediation Module uses the same Service component architecture (SCA) introduced in WebSphere Integration Developer V6.0.0 and WebSphere Process Server V6.0.0
ESB concepts: Medition Module
WebSphere ESB and Process Server introduces a new type of module, called Mediation Module, that intercept and modify messages between service requester and the service provider. Mediation module provides the ESB functions of converting protocols, routing, transformation and other custom processing on the messages. Mediation Module is the unit of deployment and runs within the WebSphere ESB or Process Server. Interactions with external service requesters and providers defined by imports and exports, whose interfaces is defined using WSDL.
A new type of module is introduced in WebSphere ESB and Process Server, called Mediation Module, provides the ESB functionality by allowing the processing the messages between service requestors and providers. This enables loosely coupled connectivity and mediation services between different service requestors and provides connecting through the bus. The Mediation module allows converting protocols, routing, transformation and other custom processing on the messages, tpically needed in an ESB environment. The WebSphere Process Server supports business modules used for business processing and the new mediation modules, whereas WebSphere ESB supports mediation modules. Service requestors interact with the mediation module in the bus via the module exports, and the module interacts with the service providers via the module imports. These export and import interfaces are defined using the WSDL.
Mediation Module: Import and Export bindings
Different kinds of requester and provider types of interactions are made available via different bindings for the imports and exports. WebSphere ESB provides support for JMS bindings- JMS 1.1 provided by WebSphere platform Messaging can exploit a variety of transports TCP/IP, SSL, HTTP(S). Allows interaction with the WebSphere family WAS, WebSphere MQ, WebSphere Message Broker. Web Services binding SOAP/ HTTP, SOAP/JMS, WSDL 1.1, Service Registry -UDDI 3.0, WS-Security, WS-Automatic Transactions. WebSphere Adapter bindings JCA Adapters -SAP, PeopleSoft, Sibel, Files, JDBC, WBI Adapters for all the rest. Built-in SCA (Default) binding Used for module to module communication-supports both synschronous and asynchronous communication. WebSphere ESB supports update this binding via the admin console allowing module to module connectivity to be changed.
Interactions with external service requesters and providers are defined by imports and exports. Import/export interfaces are defined using the Web Services Description Language (WSDL), which may contain several service operations. Different kinds of requester and provider are made available via different bindings for the imports and exports. WebSphere ESB and Process Server v6.0.1 supports JMS binding, WebServices bindings, WebSphere Adapter bindings and the default built-in SCA binding. These different bindings allows maximum flexibility for the requestors and providers to use the protocol of their choice. Use of different bindings permits easy transformation of protocols between the service requestors and providers. The import and Export bindings are same as used for Business modules in WebSphere Process Server.
Mediation flow component and Request-Response interaction
Mediation module contains a new type of SCA component, called Mediation Flow Component. Mediation Flow Components act as ‘service intermediaries’ to pass a 9potentially modified) request from a service requester to a service provider, pass a (potentially modified) response from a service provider to a service requester. Processing of requests is separated from processing of responses in the mediation flow component. Request processing within a mediation flow component can send a response back to the requester without necessarily needing to contact a service provider.
Mediation Module contain a new SCA component called Mediation flow component which acts as a service intermediary for the processing of the message. The Mediation flow component provides a standard way of processing the message independent of the binding protocol used by the service requestors or providers. It supports one way model where no response is expected or 2 way request and response model. It supports synchronous or asynchronous invocation model, similar to other SCA components. Within the Mediation flow component, the processing of the request message is performed separately from the response message. This allows different processing of the request message is performed separately from the response message. This allows different processing to occur on the request and the response side by having different mediation primitives on the request and response flows.
The mediation application developer may choose to create and handle the response within the mediation flow component without actually calling the service provider. The Mediation Module developer will need to construct the response message based on the interface definition of the module export.
Mediation Module: Contents
Mediation Module can have the following: Exports, defined using WSDL that expose the mediation module to external service requesters. Imports, defined using WSDL, that identify external service providers and their interfaces. A new type of SCA component called, Mediation flow component- this provides the mediation function on the messages between these services requestors and the providers. In cases where the only need is to transform the message from one interaction protocol to another, there may not be any need for a mediation flow component in the module. Optional SCA Java components-this is used in conjunction with the custom mediation primitive or when there is a need to use Java interface.
Mediation module contain exports, imports, a new type of SCA component called the Mediation flow component and optionally other SCA components of type. Mediation Imports are like normal SCA imports with all the supported bindings, namely, Default SCA, JMS, Web Services. Imports are the entry points into the Bus. Similarly, Mediation Exports are like normal SCA exports with all the supported bindings, namely Default SCA, JMS, Web Services. Exports are the exit point from the Bus. A new type of SCA component, called the Mediation Flow component, contains logic of how the message is processed between the input and output of the flow. Functions like message routing, transformation, augmentation, logging or any other custom processing are performed on the message within the Mediation Flow component. Lastly, the module can optionally contain SCA Java components, used to implement custom mediation primitive. More on this later in the presentation.
Mediation Flow editior is used provide the implementation of the mediation components that are used to process the message flow as it flows from the service requestor to the provider through the Enterprise Service bus. The editor contains 3 sections. The top one is the Operation Mediation section used to define the mapping of the source input operation to one or more target output operation. The map is created by visually wiring the input operation to the appropriate target out operation. Once the connection is made between a source and target operation, the middle section called the Mediation Flow section is used to create the message processing flow. Mediation Primitives are added here and wired to create the message flow between input and output operation. The bottom most section of the editor is the mediation properties section to view or modify the properties of the connection, primitives that are highlighted in the mediation flow section.
Mediation flow component design methodologies.
Two types of design methodology
Top- down design
Developer creates with Mediation Flow component with the required interfaces and references. Developers generates an implement (empty) for the Flow component This will open the Mediation Flow component editor. Using the Mediation Flow Editor, the developer create mappings from a source operation to one or more target operations.
User starts with actual implementation of the flow component does not yet have the Mediation Flow component. The mediation flow component is then used to assemble the module. This approach can be used to modify any existing design and then merging the implementation of the flow component.
WebSphere ESB provides several built-in mediation primitives and allows the capability of adding your own custom mediation for cases that are note covered by the built-in mediation primitives. Following built-in mediation primitives are provided.
1. Message Logger used to log/store message information to a database.
2. Message Filter to filter messages selectively forwarding them on to output terminals, based on simple condition expression.
3. Database lookup to access information in a database and insert it in the message. The mediation primitive is supplied with key id to look for and where in the message is the value of the key. Using the two information, the value of the specified column for the matching key is inserted in the specified location within the message.
4.XSL Transformation mediation primitive is used to transform messages using XSL transformation. This is mainly used when the target provider has a different interface than the incoming message interface. Using the mapping within the XSLT, one can map the input values to the appropriate output fields.
5. Stop mediation primitive used to stop the flow execution.
6. Fail mediation primitive used for error conditions, where the flow execution is stopped and an exception is generated.
Custom mediation primitive is used to do message processing that is not covered by other ediation primitives by executing custom logic. Custom Mediation Primitive calls a SCA Java component that you create or provide. The SCA Java component must be within the same Mediation module.
