public abstract class ServantLocatorPOA extends Servant implements ServantLocatorOperations, InvokeHandler
The ServantLocator stub is an optional base for the servant locators. It cannot serve remote invocations, as methods in {@link ServantLocatorOperations} take POA as one of parameters. Both JDK 1.5 API and OMG specifies that POA is a local object that must not be transferred to the remote invocation target.
You do not need to derive your servant locator from this stub, it is enough to implement the {@link ServantLocator} interface. But you may choose to do this if you need its functional {@link org.omg.PortableServer.ServantActivatorPOA.delegator#_ids()} method or want to keep default behaviour during pre- or post- invokcations.
