About the TopLink Sessions Editor

Use the TopLink Sessions Editor to easily manage your sessions.xml file information. The sessions.xml configures one or more sessions for your project, and associate the sessions with the project. This approach allows you to configure the following elements for each project:

Database (JDBC) login information different from that used during development (for example, external data sources for the host application server's connection pools).
JTA/JTS transaction usage
Cache synchronization
Session Broker (multiple databases appearing as a single TopLink session)

Refer to "Configuring Sessions with the Sessions XML File" for more information.
