This set of topics provide information about the service integration
technologies.
Why and when to perform this task
The service integration functionality within WebSphere Application
Server provides a highly-flexible messaging system that supports a service-oriented
architecture with a wide spectrum of quality of service options, supported
protocols, and messaging patterns. It supports both message-oriented and service-oriented
applications.
This messaging system is based on the concept of a
service
integration bus, which combines the messaging fabric and service-oriented
capabilities:
- A service-oriented infrastructure to support application description,
deployment, and invocation using the service-oriented architecture.
- Reliable message transport capability
- Both tightly and loosely coupled communications options
- Intermediary logic (mediations) to intelligently adapt message
flow in the network
- Implementation of relevant Web Services standards
You can configure service integration in a variety of different
ways; for example, to tailor the functionality to meet specific messaging
needs without needing specialized messaging point products.
Within WebSphere
Application Server, service integration provides:
- The default messaging provider as a J2EE 1.4 compliant JMS provider, fully
integrated with Application Server, supporting multi-server configurations,
and inter-operating with WebSphere MQ.
- The Service Integration Bus, which provides the first-class infrastructure
for Web Services integration of applications by leveraging the service-oriented
architecture based on Web Services standardization.
- Support for the Web services gateway, which provides you with a single
point of control, access and validation of Web service requests, and allows
you to control which Web services are available to different groups of Web
service users.
- The messaging infrastructure for On Demand Computing.
Tools for working with messaging include the following:
- Product systems administration tools for configuring and operating the
service integration bus environment.
