/** |

* {@link org.aopalliance.intercept.MethodInterceptor} for accessing RMI services |

* from JNDI.Typically used for RMI-IIOP, but can also be used for EJB home objects |
||||
* (for example, a Stateful Session Bean home). In contrast to a plain JNDI lookup, |
||||
* this accessor also performs narrowing through PortableRemoteObject. |
||||
* |
||||
* <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. |
||||
* |
||||
* <p>The JNDI environment can be specified as "jndiEnvironment" property, |
||||
* or be configured in a {@code jndi.properties} file or as system properties. |
||||
* For example: |
||||
* |
||||
* <pre class="code"><property name="jndiEnvironment"> |

* <props> |

* <prop key="java.naming.factory.initial">com.sun.jndi.cosnaming.CNCtxFactory</prop> |

* {@link FactoryBean} for RMI proxies, supporting both conventional RMI services |

||||
* 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. |

/** |
||||
* 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. |
||||
* |
||||
* <p>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 {@code java.rmi.Remote} or throw {@code java.rmi.RemoteException} |
||||
* on all methods, but in and out parameters have to be serializable. |
||||
* |
||||
* <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>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 {@code java.rmi.server.hostname} property to the |
||||
* JVM that will export the registry and/or the service using the "-D" JVM argument. |
||||
* For example: {@code -Djava.rmi.server.hostname=myserver.com} |
