Interface SessionContext

All Superinterfaces:
EJBContext
public interface SessionContext extends EJBContext
The SessionContext interface provides access to the runtime session context that the container provides for a session 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.
Since:
EJB 1.0

    • getEJBLocalObject

      EJBLocalObject getEJBLocalObject() throws IllegalStateException
      Obtain a reference to the enterprise bean local object that is associated with the instance.

      An instance of a session bean can call this method at anytime between the PostConstruct or ejbCreate and PreDestroy or ejbRemove methods, including from within these 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 enterprise bean local object currently associated with the instance.
      Throws:
      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.
