The application logic components residing in the EJB container support
the execution of business logic.
- Business Process Component
- The Business Process Component provides supporting entities so that an
application can run a business process within the Process Choreographer of WebSphere(R) Business
Integration Server Foundation.
- Single Action EJB
- As an alternative to the Process Choreographer, an application can use
a Single Action EJB to perform the business process. A Single Action EJB may
or may not use the CHA and CHA Formatter Service.
- Startup beans
- The application logic domain uses startup beans to initialize the application
logic layer entities.
- Communication services
- Communication services provide connectivity to the existing data and applications
in the enterprise systems. These services isolate the client application from
the communications complexity by providing a clear and easy public interface.
The SNA JCA LU0 Connector and the SNA JCA LU62 Connector are resource adapters
that enable business processes
- JDBC Database services
- The JDBC Database services of the Branch Transformation Toolkit interact
with a database through the JDBC protocol to provide access to database tables.
The services also map context data to database records and database records
to context data using a formatter. The Database Table Mapping service enables
toolkit applications to access databases using a common interface. The Electric
Journal service can record the services and processes used or performed by
an entity such as branch, user, or terminal. The design of each application
determines what information the service records as well as when it writes
that information.
- Generic Pool
- The Generic Pool service in the application logic layer performs
the same function as it does in the Java(TM) clients and Web Container.
