A single SOA composite application instance can reside in a single container or can be clustered across multiple containers. Another application (for example, an Oracle Application Development Framework (ADF) Business Component application) can be configured to run in the same container as the SOA composite application instance or in a different container.

Raising an event from a Java EE application can be done through a local event connection or a remote event connection:

• Local event connection

  If the publisher resides on the same Oracle WebLogic Server as the application and the publisher uses a local business event connection factory, the event is raised through a local event connection.

• Remote event connection

  If the caller resides in a different container (different JVM) then the application, the event is raised through a remote event connection.

If another application (for example, an Oracle ADF Business Component application) is configured to run in the same container as the SOA composite application, it is optimized to use local event connections.
