|

* result objects. Uses Java serialization just like RMI, but provides the |
|
||||||
* same ease of setup as Caucho's HTTP-based Hessian and Burlap protocols. |
|
||||||
* |
|
||||||
* <P>HTTP invoker is a very extensible and customizable protocol. |
|
||||||
* It supports the RemoteInvocationFactory mechanism, like RMI invoker, |
|
||||||
* allowing to include additional invocation attributes (for example, |
|
||||||
* a security context). Furthermore, it allows to customize request |
|
||||||
* execution via the {@link HttpInvokerRequestExecutor} strategy. |
|
||||||
* |
|
||||||
* <p>Can use the JDK's {@link java.rmi.server.RMIClassLoader} to load classes |
|
||||||
* from a given {@link #setCodebaseUrl codebase}, performing on-demand dynamic |
|
||||||
* code download from a remote location. The codebase can consist of multiple |
|
||||||
* URLs, separated by spaces. Note that RMIClassLoader requires a SecurityManager |
|
||||||
* to be set, analogous to when using dynamic class download with standard RMI! |
|
||||||
* (See the RMI documentation for details.) |
|
||||||
* |
|
||||||
* <p><b>WARNING: Be aware of vulnerabilities due to unsafe Java deserialization: |
|
||||||
* Manipulated input streams could lead to unwanted code execution on the server |
|
||||||
* during the deserialization step. As a consequence, do not expose HTTP invoker |
|
||||||
* endpoints to untrusted clients but rather just between your own services.</b> |
|
||||||
* In general, we strongly recommend any other message format (e.g. JSON) instead. |

/** |
|
||||||
* {@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> |
|
||||||
* <prop key="java.naming.provider.url">iiop://localhost:1050</prop>

|

|

* <p>Typically used for RMI-IIOP (CORBA), 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 {@link javax.rmi.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. |

* {@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. |

/** |
|
||||||
* 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} |
