Hi there.
I'm using the dosgi-cxf(rs) on eclipse 3.6.1.
I have register a exception/responseException Mapper, but i cannot get my
exception.
This exception comes from original CXF source code;
java.lang.reflect.UndeclaredThrowableException

I got only Invocation Exception resource throws my custom exception ,but it
works when i fix cxf source
code(org.apache.cxf.dosgi.dsw.handlers.ServiceInvocationHandler)
ServiceInvocationHandler.java

this.serviceObject = serviceObject;
introspectType(iType);
}
public Object invoke(Object proxy, final Method m, Object[] params)
throws Throwable {
if (OBJECT_METHODS.contains(m)) {
if (m.getName().equals("equals")) {
params = new Object[]
{Proxy.getInvocationHandler(params[0])};
}
return m.invoke(this, params);
}
