27  * FactoryBean for a specific port of a JAX-RPC service.
28  * Exposes a proxy for the port, to be used for bean references.
29  * Inherits configuration properties from {@link JaxRpcPortClientInterceptor}.
30  *
31  * <p>This factory is typically used with an RMI service interface. Alternatively,
32  * this factory can also proxy a JAX-RPC service with a matching non-RMI business
33  * interface, i.e. an interface that mirrors the RMI service methods but does not
34  * declare RemoteExceptions. In the latter case, RemoteExceptions thrown by the
35  * JAX-RPC stub will automatically get converted to Spring's unchecked
36  * RemoteAccessException.
37  *
38  * <p>If exposing the JAX-RPC port interface (i.e. an RMI interface) directly,
39  * setting "serviceInterface" is sufficient. If exposing a non-RMI business
40  * interface, the business interface needs to be set as "serviceInterface",
41  * and the JAX-RPC port interface as "portInterface".
