Session Bean Applications

For J2EE applications with non-entity EJB, it is common to package the application in an Enterprise Archive (EAR) file made up of various J2EE application component archives as Figure 9-3 shows.

Description of "Figure 9-3 Packaging a J2EE Application With Non-Entity EJB"

The component archives with TopLink dependencies include:

TopLink Domain JAR
EJB JAR

TopLink Domain JAR

The domain JAR contains the TopLink files and domain objects required by the application, including:

sessions.xml File
project.xml File (or the compiled project.class file if you are not using XML files for deployment)
The mapped classes required by the application, in a fully-resolved directory structure

When you create the JAR file, the JAR building utility automatically creates a directory structure within the JAR. Ensure that the sessions.xml file and the project.xml file (or project.class file) appear at the root of the JAR file. Also ensure that the class directory structure starts at the root of the JAR.

If you do not store the project.xml or sessions.xml files at the root of the JAR file, see "Packaging With TopLink Metadata File Resource Paths".

EJB JAR

In this type of application, the EJB JAR contains non-entity EJB. Consequently, its orion-ejb-jar.xml does not contain persistence-manager or pm-properties entries. These entries apply only to CMP applications.
