The EJB adapter enables Enterprise JavaBeans and SOA composite applications to interact by passing Java interfaces (does not use a WSDL file to define the interface) or SDO parameters (uses a WSDL file to define the interface).

SDOs enable you to modify business data regardless of how it is physically accessed. Knowledge is not required about how to access a particular back-end data source to use SDO in a SOA composite application. Consequently, you can use static or dynamic programming styles and obtain connected and disconnected access.

Enterprise JavaBeans are server-side domain objects that fit into a standard component-based architecture for building enterprise applications with Java. These objects become distributed, transactional, and secure components.

Java interfaces eliminate the need for WSDL file definitions. This type of integration provides support with the following objects:

• Native Java objects

• Java Architecture for XML Binding (JAXB)

Dragging an EJB icon into a swimlane of the SOA Composite Editor invokes the Create EJB Service dialog for specifying configuration properties.
