Constructor Detail

StatefulHandleImpl

public StatefulHandleImpl(int objectName,
                          String jndiName,
                          Invoker invoker,
                          String invokerProxyBinding,
                          Object id,
                          Object invokerID)

Create an ejb handle for a stateful session bean.
Parameters:: objectName - - the session container jmx name; jndiName - - the session home ejb name; invoker - - the invoker to request the EJBObject from; invokerProxyBinding - - the type of invoker binding; id - - the session id

Method Detail

getID

public Object getID()

Returns:: the internal session identifier

getJNDIName

public String getJNDIName()

Returns:: the jndi name

getEJBObject

public javax.ejb.EJBObject getEJBObject()
                                 throws RemoteException

Handle implementation. This differs from Stateless and Entity handles which just invoke standard methods (create and findByPrimaryKey respectively) on the Home interface (proxy). There is no equivalent option for stateful SBs, so a direct invocation on the container has to be made to locate the bean by its id (the stateful SB container provides an implementation of getEJBObject). This means the security context has to be set here just as it would be in the Proxy.

Specified by:: getEJBObject in interface javax.ejb.Handle

Returns:: EJBObject reference.
Throws:: ServerException - Could not get EJBObject.; RemoteException

isLocal

protected boolean isLocal()

Returns wether we are local to the originating container or not.
