Hi Rancher,

I just a simple question,

Its true about that in the new specification the old JAX-RPC2.0 become JAX-WS ?

And if thats is true (i think that is), why the change, I mean, (i dont know nothing about web services), that change is complety diference about the two, o what? just want to know a brief about that.

Thank you in advance

First of all, there was no JAX-RPC 2.0 and there isn't one. And, it didn't become JAX-WS. JAX-WS is evolution of JAX-RPC. It has some features and provisions that JAX-RPC didn't have. I am not going to go over 'what is new in JAX-WS' but here are some new things in JAX-WS:
1. New programming model - annotation based
2. New packaging model - webservices.xml, jax-rpc mapping files are gone
3. New binding mechanism JAXB based as opposed to JAX-RPC binding
3. Support for new standards SOAP 1.2, REST, JSON binding, MTOM and more
4. Support for new features such as asynchronous invocation

Use this as your starting point if you want to learn more: - Coming soon!

It's correct to say that there was never a released JAX-RPC 2.0. There was a planned JAX-RPC 2.0 however, which was renamed to JAX-WS before the final release.

One of the reason for that was that web services evolved from being mostly about RPC, and became more general in nature (more document-oriented).
I agree. Here's the link:

It's not a secret anymore!
