Method Detail

destroyVM

void destroyVM()
        throws RemoteException,
               ActivationException

Cause the hosting VM to exit. This method should (in effect) spawn a separate thread to do the actual work asynchronously, and make a reasonable attempt to let this remote call return successfully. As such, a successful return from this method does not mean that the VM has been destroyed. Although the service should make a reasonable attempt to let this remote call return successfully, the service must not wait indefinitely for other (in-progress and subsequent) remote calls to finish before proceeding to destroy its hosting VM. Once this method has been called, the service can, but need not, reject all other (in-progress and subsequent) remote calls to the service.

Throws:

RemoteException - if there was a problem communicating with the shared group object

ActivationException - if there was a problem creating an activatable shared group instance
