service components

Developers implement service components using any of a variety of different software technologies, or component types.

Stack layers have been replaced by service components and there is so much reuse that the stacks have all but disappeared.

As I show below, most of the time, this process is routed through the Enterprise Service Bus (ESB) at the service components layer.

WebSphere Process Server models a composite SOA application as a set of SCA-compliant service components.

Integration in SOA is achieved at the service components layer, with the primary concept or tool being an ESB, as shown in Figure 7.

Web services are often used to enable remote access to existing service components.

Each file from all library types except the libraries of discarded service components must be labeled with version numbers.

Design services enable models to be staged into design, and include the ability to attribute the process with service components.

Configuration control procedures shall ensure that the integrity of systems, services and service components are maintained.

Mediations in WebSphere ESB are service components following the SCA standard, and thus can be accessed as Web services.

Service components with built-in points-of-variability allow users to configure these services to meet different requirements.

WebSphere Process Server adds the top two component tiers: Service components and the remaining supporting services.

WebSphere Integration Developer is an IDE for implementing service components.

A business process is created by the composition and choreography of business services provided by service components.

It provides a graphical UI to specify detail properties of components, bindings, and QoS qualifiers for the service components.

Conceptually, SCA describes all integration artifacts as service components with well defined interfaces.

You can use either software to partition application logic into modular Web service components of multiple business processes.

Defining an appropriate URI when deploying the service components will select the WebSphere MQ transport.

SCA enables integration developers to implement SOA applications as sets of service components.

You can use SCA to invoke service components through both synchronous and asynchronous programming styles.

JMS binding - Java Messaging Service (JMS) bindings make service components accessible via the JMS.

You use an assembly diagram to wire your service components together within a module.

A lot of new classes are also created during service realization to refine the service components and services.

A secondary benefit comes from implementing rules as separate service components in SOA.

The core platform is a runtime container for unit service components called GBeans.

Business objects - A format for data exchange between service components, based on service data objects (discussed below).

When invoking service components synchronously within a module using the reference, the data is passed by-reference.

Service integrators in turn may choose to build their offerings by using service components from other vendors.

SCA modules contains SCA components or service components.

In the previous articles in this series, you learned how to implement your service components using business processes and state machines.

A similar situation may arise with the service components.

It's a generic framework for gluing together service components.

It is also designed to make that information highly available to the service components.

A J2EE server is just one specific assembly of existing open source service components.

Canonical service components, that is, services designed as services from the ground up, are not essential to make this scheme work.

In the course of processing, the ActionController or the WSManager can call the required methods in the relevant Model service components.

XML is the language that is used for communication between Web service components.

Seam is a "lightweight framework" because it promotes the use of POJO (plain old Java objects) as service components.

Programmers need tools to develop new business logic, such as J2EE components, portlets, and other custom service components.

We assume there are 10 categories of services, and assign to each proxy 2 to 6 of them as its available service components.

Composition of service components using Service Component Architecture (SCA)

The login service and profile service components, to provide local services for managing employee state

XML. The language (data format) used by the Web service components

Removing Instant Messaging, Chat, ccMail, MSMail, and Key Management Service Components

A service timeout has been configured in one or more of the service components
