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 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 ServantLocator interface. But you may choose to do this if you need its functional delegator method or want to keep default behaviour during pre- or post- invokcations.
