User: mnf999 Date: 01/11/14 08:43:19 Added: src/main/org/jboss/invocation Invocation.java Log: The new Invocation object, it is just a generalized invocation that carries Transaction and security with it. Then we keep some variables directly but it should really work through the payload. The payload is just a map of objects that the invocation carries around. The old MethodInvocation is now an extension of this guy. The Invocation also carries a list of mbeans that he is supposed to go through. This will be interesting when we move to the "router" view of the JMX base and the Invocations are just stand-alone objects that travel through the base. The EJB view here is secondary. Note: I have left "funky" constructors to provide backward compatibility with the old codebase and way of doing things.
