org.springframework.remoting.rmi.RmiServiceExporter
RMI exporter that exposes the specified service as RMI object with the specified name. Such services can be accessed via plain RMI or via {@link RmiProxyFactoryBean}. Also supports exposing any non-RMI service via RMI invokers, to be accessed via {@link RmiClientInterceptor} / {@link RmiProxyFactoryBean}'s automatic detection of such invokers.
With an RMI invoker, RMI communication works on the {@link RmiInvocationHandler}level, needing only one stub for any service. Service interfaces do not have to extend java.rmi.Remote or throw java.rmi.RemoteException on all methods, but in and out parameters have to be serializable.
The major advantage of RMI, compared to Hessian and Burlap, is serialization. Effectively, any serializable Java object can be transported without hassle. Hessian and Burlap have their own (de-)serialization mechanisms, but are HTTP-based and thus much easier to setup than RMI. Alternatively, consider Spring's HTTP invoker to combine Java serialization with HTTP-based transport.
Note: RMI makes a best-effort attempt to obtain the fully qualified host name. If one cannot be determined, it will fall back and use the IP address. Depending on your network configuration, in some cases it will resolve the IP to the loopback address. To ensure that RMI will use the host name bound to the correct network interface, you should pass the java.rmi.server.hostname property to the JVM that will export the registry and/or the service using the "-D" JVM argument.
