All Implemented Interfaces:

FactoryBean, InitializingBean

public class RmiProxyFactoryBean

extends RemoteProxyFactoryBean

Factory bean for transparent RMI proxies. Behaves like the proxied service when used as bean reference, exposing the specified service interface. The service URL must be a valid RMI URL like "rmi://localhost:1099/myservice".

Transparent means that RMI communication works on the RemoteInvocationHandler level, needing only one stub for any service. Service interfaces do not have to extend java.rmi.Remote or throw RemoteException on all methods, but in and out parameters have to be serializable.

This proxy factory can only access RMI objects that got exported with a RemoteInvocationWrapper, i.e. working on the RemoteInvocationHandler level.

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.
