Accessing spring-deployed RMI service with a non-spring client

[liangjh]

Hi,

The server has deployed an RMI-based service using spring remoting.

Is there a specific way for a non-spring client to call these services? Does the client have to look up a specific spring interface ?

Thanks.

This depends on whether the server exposes a traditional RMI service (implementing the Remote interface, declaring RemoteException) or a Spring "RMI Invoker" service (any business interface as service interface).

In the traditional RMI case, simply perform a standard RMI Naming lookup on the client side. There are no Spring specifics involved then.

MyService proxy = (MyService) Naming.lookup("rmi://localhost:1099/myService");

In the RMI Invoker case, you need to build a Spring-specific RMI proxy like as follows:

RmiClientInterceptor rmiClient = new RmiClientInterceptor();
rmiClient.setServiceUrl("rmi://localhost:1099/myService");
MyService proxy = (MyService) ProxyFactory.getProxy(MyService.class, rmiClient);

which involves the Spring-specific AOP ProxyFactory and RmiClientInterceptor classes. This is the equivalent of a RmiProxyFactoryBean definition in a Spring application context.

Hi,

If I have deployed the service via HTTP, would the code from a non-spring client be similar along the lines of the following:

--//--

HttpInvokerClientInterceptor remoteClient = new HttpInvokerClientInterceptor();
remoteClient.setServiceUrl(serviceUrl);
remoteService = (MyRemoteService) ProxyFactory.getProxy(MyRemoteService.class, remoteClient);

--//--

This keeps telling me that it can't find the service at the URL. I'm pretty sure that the service is deployed properly. Any ideas ?

Thanks
