/**
* {@link org.aopalliance.intercept.MethodInterceptor} for accessing a specific port
* of a JAX-RPC service. Uses either {@link LocalJaxRpcServiceFactory}'s facilities
* underneath or takes an explicit reference to an existing JAX-RPC Service instance
* (e.g. obtained via a {@link org.springframework.jndi.JndiObjectFactoryBean}).
*
* <p>Allows to set JAX-RPC's standard stub properties directly, via the
* "username", "password", "endpointAddress" and "maintainSession" properties.
* For typical usage, it is not necessary to specify those.
*
* <p>In standard JAX-RPC style, this invoker is used with an RMI service interface.
* Alternatively, this invoker can also proxy a JAX-RPC service with a matching
* non-RMI business interface, that is, an interface that declares the service methods
* without RemoteExceptions. In the latter case, RemoteExceptions thrown by JAX-RPC
* will automatically get converted to Spring's unchecked RemoteAccessException.
*
* <p>Setting "serviceInterface" is usually sufficient: The invoker will automatically
* use JAX-RPC "dynamic invocations" via the Call API in this case, no matter whether
* the specified interface is an RMI or non-RMI interface. Alternatively, a corresponding
* JAX-RPC port interface can be specified as "portInterface", which will turn this
* invoker into "static invocation" mode (operating on a standard JAX-RPC port stub).
