Java EE Service Engine Features

The features of theJava EE Service Engine are:

• Java EE service units - Using Java EE service units, end users can deploy and manage a composite application as a single entity: a JBI service assembly.

• Transactions support - Enables Java EE web services and JBI services to participate in a single transaction. For example, a BPEL process can call an EJB bean that updates a database, all in the same transaction.

• Security support - Enables separate JBI components to make use of a single authentication mechanism. In practice, a user signs on once, and the JBI system propagates the security credentials to the various JBI components as needed.

• Code upgrade to JAX-WS 2.1

• Endpoint enabling through jbi.xml

• Support for RPC/Literal style operations

• Direct invocation of endpoints

• Packaging Java EE applications as part of the composite application

• Cluster support - Enables you to deploy a Java EE service unit to an application server cluster. When the JBI service assembly is deployed to the cluster, the Java EE service units are also deployed to each server instance in the cluster.

• Message properties propagation — This new feature supports propagation and reception of Normalized message properties. This feature allows additional properties to be propagated between Java EE components and JBI components. Propagation and reception of these message properties is handled by the Java EE Service Engine. For example, a web service client can pass additional message properties while invoking a JBI endpoint (eg. BPEL endpoints). The endpoint can use these properties and also send back additional properties to the client.
