Examples of org.springframework.remoting.RemoteAccessException

org.springframework.remoting.RemoteAccessException
Generic remote access exception. A service proxy for any remoting protocol should throw this exception or subclasses of it, in order to transparently expose a plain Java business interface.
When using conforming proxies, switching the actual remoting protocol e.g. from Hessian to Burlap does not affect client code. Clients work with a plain natural Java business interface that the service exposes. A client object simply receives an implementation for the interface that it needs via a bean reference, like it does for a local bean as well.
A client may catch RemoteAccessException if it wants to, but as remote access errors are typically unrecoverable, it will probably let such exceptions propagate to a higher level that handles them generically. In this case, the client code doesn't show any signs of being involved in remote access, as there aren't any remoting-specific dependencies.
Even when switching from a remote service proxy to a local implementation of the same interface, this amounts to just a matter of configuration. Obviously, the client code should be somewhat aware that it might be working against a remote service, for example in terms of repeated method calls that cause unnecessary roundtrips etc. However, it doesn't have to be aware whether it is actually working against a remote service or a local implementation, or with which remoting protocol it is working under the hood. @author Juergen Hoeller @since 14.05.2003
