jca

Calls to the optimized local adapter invocation or send request APIs do not result in an inbound JCA request to drive into the target EJB.

You should now be able to see how a JCA resource adapter would provide the JMS destination objects by using administered objects.

Second, if the data sources are legacy systems, you might have to use adapters or JCA.

The JCA is part of the J2EE standard and specifies the system contracts to be implemented by a resource adapter.

One of the aims of version 1. 5 of the specification is to allow a JMS provider to be implemented as a JCA resource adapter.

You don't necessarily need an application server for it as you can use a pluggable JCA container like Jencks.

JCA allows you to integrate existing EIS while maintaining correct transactional semantics required for e-business.

Figure 3 shows how parts of a JCA resource adapter can be mapped to corresponding artifacts of WSDL.

JCA 1. 5 introduces an elegant solution to this problem in the form of the ValidatingManagedConnectionFactory interface, shown in Listing 5.

In this article, I'll explain how the JCA transaction contract helps implement transactional behavior in e-business applications.

We've already mentioned JMS and JCA, which are the protocols that are probably the most relevant to enterprise application integration.

JCA is a set of interfaces that the adapter writer must implement, using the application server as the runtime.

The JCA gives you two options for handling transactions: programmatic transaction demarcation or declarative transaction demarcation.

JCA 1. 0 Was lacking in a few areas that made it less than ideal for integration.

The JCA Adapter for JDBC utilizes the ORDER_EVENT table to invoke downstream business processes as shown in Figure 3.

TMJ involvement in children with Juvenile Chronic Arthritis (JCA) will frequently cause disturbance of the growth of the mandible.

Key to this integration is the JCA transaction management contract, between the resource adapter and the J2EE application server.

Depending on the scope of the implementation, a JCA adapter can support no transaction, local transaction, or XA transaction.

You can deploy a JCA-compliant resource adapter to any J2EE-compliant application server.

JCA defines a mechanism for a container to provide credentials to the resource adapter that will be used on the connection.

XA transactions are a complex subject, and specifics other than those that relate to JCA are beyond this article's scope.

During the design and implement, security characteristic and technology advantage of JCA, JCE, JAAS and JSSE stacked out a mile.

This plan configures the components for an RA instance, as detailed for a deployment descriptor in the JCA 1. 5 specification.

Let's take a look at the integration solution based on the architecture described in the JCA specification.

The extensions can be added to any existing resource adapter that is compliant to the JCA.

For a JMS provider, the JCA specification recommends that the names and values given in Table 1 be supported.

Specification defined: Activation specifications are part of a standards specification (JCA 1. 5).

Conversation support is being positioned as a future J2EE extension for building conversational JCA adapters.

The only requirement is that the Java environment acts as an JCA provider.

In summary, this restriction makes it easier to implement a JMS provider as a JCA resource adapter.

The final pre-configuration step is to specify JCA authentication values for access to JMS resources.

Java Connector Architecture (JCA) provides a non-propriety framework for creating a J2EE adaptive component to your application.

JCA is a standard that promotes portability across different application server vendors.

Subsequently, other specifications were published to extend the features provided by JCA.

Shows the different types of interfaces defined by the JCA specification.

In the third and final article of this series, I'll cover the JCA 1. 5 message-inflow contract, better known as message-driven bean support.

The first set addresses limitations in the way application servers could manage connection handles under previous JCA versions.

The most prominent of these interfaces are JMS and JCA.

As its name suggests, this specification also provides an alternative to JCA work management.

Now JCA defines a standard architecture for connecting between applications and each type of EIS.

The JCA 1. 5 specification has addressed this issue by introducing the two new interfaces, shown in Listing 3.

Unfortunately, the JCA specification does not define the type of this property or what it means.

Imagine the development of a custom J2EE JCA connector for accessing a legacy system, to be used remotely by a workflow application.

JCA enables an EIS vendor to provide a standard resource adapter for its particular system.

Two levels of programming interfaces are defined in the JCA specification.

If a JTA manager is required, a simple yet elegant solution is to use the jca connector from Jackrabbit contrib package.

Configuring the JCA connector is outside the scope of this article; however you can find an example using Jencks inside JCR module sample.

Journal of Computational Acoustics - JCA.

Life cycle management: Allows the application server to control the life cycle of a JCA resource adapter.

SCA defines several different types of bindings, including Web service, stateless session EJB, JMS, JCA, SCA default binding, and so on.

JCA specifications define more contracts for Quality of Service aspects, such as security, workload management, and connection management.

Thus, we can describe all of the JMS- and JCA-specific information about a service in the protocol binding part of the WSDL definition.

It supports connectivity to EIS applications via IBM WebSphere Adapters based on JCA specifications.

This has been rectified in JCA 1. 5 with the introduction of the ResourceAdapter interface, shown in Listing 6.

The JCA specification doesn't place any restriction on the circumstances under which an MDB will be driven.

We have said above that the J2EE standard defines ways to integrate non-J2EE applications by the use of APIs like JMS and JCA.

As mentioned above, a JCA Resource Adapter is used to link JMS resources and the SIB.

Prior to JCA 1. 5, the application server always acted as the transaction coordinator.

jca. jar Supplied by unit-test environment.

Technologies such as JCA and JMS still get used, but their APIs are not use directly by the component developer.

The JCA 1. 5 Specification describes two phases to this process.

You can run JCA adapters in managed and unmanaged mode.

This is another major benefit that ActiveMQ brings to the table -- it has a ready-for-integration JCA 1. 5-compliant RA implementation.

On line 014, the cimRequest Document is sent to the CIMOM through the CIM JCA adapter.

A closer look at these models will help you understand the performance improvements JCA 1. 5 brings in this area.

For a summary of JCA 1. 5 Enhancements.

Many aspects of JCA deserve a closer and more detailed look by themselves, but we will leave that task to other articles and papers.

The JCA 1. 5 specification has a solution: lazy enlistment.

JCA 1. 5 Supports bidirectional exchange while JCA 1. 0 Adapters support service calls only.

These include J2EE 1. 3 applications and JCA 1. 0 adapters, and do not call any new V6 APIs.

Figure 2 shows the ActiveMQ JCA 1. 5-compliant RA.

Another pair of new interfaces in JCA 1. 5 Prevents unnecessary enlistment of
