Ok,
But let's suppose that I want to invoke, inside an invoker, a different
operation from a component.
For this invocation chain:
1) add -> Interceptor for the add -> Interceptor for the addMethod ->
addMethod
Suppose that I want to invoke the addMethod2 instead of addMetdhod, and both
operation belong to the same component. In this way, I cannot use the
getNext().invoke(msg);
I am trying to create a different invoker:
RuntimeComponent component = msg.getTo().getComponent();
ImplementationProvider implProvider =
component.getImplementationProvider();
implProvider.createInvoker(*RuntimeComponentService arg1*, *Operation arg2*
);
However, I am having some problems to create a RuntimeComponentService and a
Operation for the addMethod2. Is it possible? Am I doing the right thing, or
there is another way to do it?
Thanks
