Inbound event notification complements outbound request processing, enabling
adapters to provide bidirectional communication between business processes and
EIS applications.
The IBM WebSphereAdapter portfolio of adapters is based on the Java 2 Platform,
Enterprise Edition (J2EE) standard. JCA is a standardarchitecture for integrating
J2EE applications with enterprise information systems. Each of these systems
provides native APIs for identifying a function to call, specifying its input data,
and processing its output data. The goal of the JCA standardis to provide an
independent API for coding these functions, to facilitate data sharing, and to
integrate J2EE applications with existing and other enterprise information systems.
The JCA standard accomplishes this by defining a series of contracts that govern
interactions between an EIS and J2EE components within an application server.
Fully compliant with the JCA standard, WebSphereAdapters have been developed
to run on multiple server runtimes. AWebSphere Adapter does the following:
vIntegrates with multiple server runtimes, including WebSphereProcess Server,
WebSphereEnterprise Service Bus, and WebSphere Application Server.
vConnects an application running on WebSphereProcess Server with an EIS.
vEnables data exchange between the application and the EIS.
Each WebSphereAdapter is made up of the following:
vAn implementation of the (J2EE) Connector Architecture (JCA), version 1.5,
which supports WebSphereProcess Server and WebSphere Application Server.
vAn enterprise metadata discovery component.
Youuse this component with the external service discovery wizard to introspect
the EIS to discover and generate business objects and other service component
architecture (SCA) artifacts that are compiled in a standard enterprise
application archive (EAR) file. Youcan also use the external service discovery
wizard to build a service (rather than discover a service). For example, you can
use the enterprise service discovery wizard to build services (based on search
criteria you provide), and generate business objects and interfaces.
The enterprise metadata discovery component implements version 1.1 of the
enterprise metadata discovery specification.
