All Implemented Interfaces:

Advice, InitializingBean, Interceptor, MethodInterceptor

Direct Known Subclasses:

BurlapProxyFactoryBean

public class BurlapClientInterceptor

extends CauchoRemoteAccessor

implements MethodInterceptor

Interceptor for accessing a Burlap service. Supports authentication via username and password. The service URL must be an HTTP URL exposing a Burlap service.

Burlap is a slim, XML-based RPC protocol. For information on Burlap, see the Burlap website

Note: Burlap services accessed with this proxy factory do not have to be exported via BurlapServiceExporter, as there isn't any special handling involved. Therefore, you can also access services that are exported via Caucho's BurlapServlet.
