All Implemented Interfaces:

ISession

public class DetachedSession
extends java.lang.Object
implements ISession

The DetachedSession is an ISession. It allows access to a specific application with all its properties but has no connection to the server or other server objects. It has no builtin support for the SessionContext. The DetachedSession is not bound to a DefaultSessionManager and does not fire session created or destroyed events. It is also not validated against the configured security manager.
