oracle.jbo.server
Class SessionImpl

java.lang.Object
  oracle.jbo.server.SessionImpl

All Implemented Interfaces:

Session

public class SessionImpl

extends java.lang.Object

implements Session

The default server-side implementation of the Session interface. A session context represents an application's session. A session object is instantiated for each root application module when the application module is activated (see ApplicationModuleImpl.activate()). The session object is garbage collected when the root application module is garbage collected.

This class may be extended by application developers who are interested in loading session specific context at session instantiation. For example, an application may extend the init method with logic to load application specific context like the local currency into the session context. Additionally, the getTransactionHandlerFactory may be overriden by an extending class to return a custom TransactionHandlerFactory.

Custom implementations of this interface may be identified to the framework with the SessionClass server property.

Since:

JDeveloper 3.0
