/**
* {@link org.springframework.beans.factory.FactoryBean} for a specific port of a
* JAX-RPC service. Exposes a proxy for the port, to be used for bean references.
* Inherits configuration properties from {@link JaxRpcPortClientInterceptor}.
*
* <p>This factory is typically used with an RMI service interface. Alternatively,
* this factory can also proxy a JAX-RPC service with a matching non-RMI business
* interface, i.e. an interface that mirrors the RMI service methods but does not
* declare RemoteExceptions. In the latter case, RemoteExceptions thrown by the
* JAX-RPC stub will automatically get converted to Spring's unchecked
* RemoteAccessException.
*
* <p>If exposing the JAX-RPC port interface (i.e. an RMI interface) directly,
* setting "serviceInterface" is sufficient. If exposing a non-RMI business
* interface, the business interface needs to be set as "serviceInterface",
* and the JAX-RPC port interface as "portInterface".
