java.lang.Object org.springframework.remoting.jaxrpc.LocalJaxRpcServiceFactory org.springframework.remoting.jaxrpc.JaxRpcPortClientInterceptor
public class JaxRpcPortClientInterceptor
Interceptor for accessing a specific port of a JAX-RPC service. Uses either LocalJaxRpcServiceFactory's facilities underneath, or takes an explicit reference to an existing JAX-RPC Service instance (for example looked up via JndiObjectFactoryBean).
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.
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.
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.

public void setServiceInterface(Class serviceInterface)
Calls on the specified service interface will either be translated to the underlying RMI port interface (in case of a "portInterface" being specified) or to dynamic calls (using the JAX-RPC Dynamic Invocation Interface).
The dynamic call mechanism has the advantage that you don't need to maintain an RMI port interface in addition to an existing non-RMI business interface. In terms of configuration, specifying the business interface as "serviceInterface" will be enough; this interceptor will automatically use dynamic calls in such a scenario.

public Class getServiceInterface()
public void setPortInterface(Class portInterface)
The interface must be suitable for a JAX-RPC port, that is, it must be
an RMI service interface (that extends java.rmi.Remote
).
NOTE: Check whether your JAX-RPC provider returns thread-safe port stubs. If not, use the dynamic call mechanism instead, which will always be thread-safe. In particular, do not use JAX-RPC port stubs with Apache Axis, whose port stubs are known to be non-thread-safe.

enforced through overriding alwaysUseJaxRpcCall

each can be post-processed via postProcessJaxRpcCall

Default is "false"; if an RMI interface is specified as "portInterface" or "serviceInterface", it will be used to create a JAX-RPC port stub.
Can be overridden to enforce the use of the JAX-RPC Call API, for example if there is a need to customize at the Call level. This just necessary if you you want to use an RMI interface as "serviceInterface", though; in case of only a non-RMI interface being available, this interceptor will fall back to the Call API anyway.
