 /**
 * {@link org.aopalliance.intercept.MethodInterceptor} for accessing conventional
 * RMI services or RMI invokers. The service URL must be a valid RMI URL
 * (e.g. "rmi://localhost:1099/myservice").
 *
 * <p>RMI invokers work at the RmiInvocationHandler level, needing only one stub for
 * any service. Service interfaces do not have to extend {@code java.rmi.Remote}
 * or throw {@code java.rmi.RemoteException}. Spring's unchecked
 * RemoteAccessException will be thrown on remote invocation failure.
 * Of course, in and out parameters have to be serializable.
 *
 * <p>With conventional RMI services, this invoker is typically used with the RMI
 * service interface. Alternatively, this invoker can also proxy a remote RMI 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 RMI stub will automatically get converted to
 * Spring's unchecked RemoteAccessException.

 /**
 * {@link FactoryBean} for RMI proxies, supporting both conventional RMI services
 * and RMI invokers. Exposes the proxied service for use as a bean reference,
 * using the specified service interface. Proxies will throw Spring's unchecked
 * RemoteAccessException on remote invocation failure instead of RMI's RemoteException.
 *
 * <p>The service URL must be a valid RMI URL like "rmi://localhost:1099/myservice".
 * RMI invokers work at the RmiInvocationHandler level, using the same invoker stub
 * for any service. Service interfaces do not have to extend {@code java.rmi.Remote}
 * or throw {@code java.rmi.RemoteException}. Of course, in and out parameters
 * have to be serializable.
 *
 * <p>With conventional RMI services, this proxy factory is typically used with the
 * RMI service interface. Alternatively, this factory can also proxy a remote RMI
 * 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 RMI stub will automatically get converted to
 * Spring's unchecked RemoteAccessException.
 *
 * <p>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.

 * <p>Can be used to set up and pass around the actual Registry object to

 * object that needs to work with RMI is Spring's {@link RmiServiceExporter},
 * which either works with a passed-in Registry reference or falls back to

 *
 * <p>Also useful to enforce creation of a local RMI registry at a given port,
 * for example for a JMX connector. If used in conjunction with
 * {@link com.fr.third.springframework.jmx.support.ConnectorServerFactoryBean},
 * it is recommended to mark the connector definition (ConnectorServerFactoryBean)
 * as "depends-on" the registry definition (RmiRegistryFactoryBean),
 * to guarantee starting up the registry first.
 *
 * <p>Note: The implementation of this class mirrors the corresponding logic
 * in {@link RmiServiceExporter}, and also offers the same customization hooks.
 * RmiServiceExporter implements its own registry lookup as a convenience:
 * It is very common to simply rely on the registry defaults.
