下面是EJB2.0对SessionContext的文档，来自SUN The SessionContext interface provides access to the runtime session context that the container provides for a session enterprise Bean instance. The container passes the SessionContext interface to an instance after the instance has been created. The session context remains associated with the instance for the lifetime of the instance. --------------------------------------------------------------------------------Method Summary EJBLocalObject getEJBLocalObject() Obtain a reference to the EJB local object that is currently associated with the instance.

Method Detail
getEJBLocalObject
public EJBLocalObject getEJBLocalObject()
throws java.lang.IllegalStateException
Obtain a reference to the EJB local object that is currently associated with the instance.
An instance of an entity enterprise Bean can call this method only when the instance is associated with an EJB local object identity, i.e. in the ejbActivate, ejbPassivate, ejbPostCreate, ejbRemove, ejbLoad, ejbStore, and business methods. An instance can use this method, for example, when it wants to pass a reference to itself in a method argument or result.
Returns:
The EJB local object currently associated with the instance.
Throws:
java.lang.IllegalStateException - Thrown if the instance invokes this method while the instance is in a state that does not allow the instance to invoke this method, or if the instance does not have a local interface.
EJBLocalObject getEJBLocalObject()
Obtain a reference to the EJB local object that is currently associated with the instance. EJBObject getEJBObject()
Obtain a reference to the EJB object that is currently associated with the instance. javax.xml.rpc.handler.MessageContext getMessageContext()
Obtain a reference to the JAX-RPC MessageContext. Methods inherited from interface javax.ejb.EJBContext getCallerIdentity, getCallerPrincipal, getEJBHome, getEJBLocalHome, getEnvironment, getRollbackOnly, getTimerService, getUserTransaction, isCallerInRole, isCallerInRole, setRollbackOnly
