I've been studying about WSIT, a project to create a good interoperability between Java and .Net webservices.
According to documentation, we can use the WSIT libraries to add to webservices the MTOM, WS-Security WS-Trust, WS-Conversation, Ws-Adressing etc.
For WS-Security case I know that WSIT project is a good implementation choice, but to Addressing and Mtom cases, the specifications has a good and interoperable (I think) support in the JAX-WS. You don't need WSIT libraries to write interoperable MTOM and Addressing services (I suppose).
Am I right? To which tecnologies is the WSIT useful, in view of that the current JAX-WS specification provides interoperable suport to tecnologies like mtom and addressing.
