Answer 1

I prefer JAX-WS (with JAXB 2.1 databinding) over the other liberaries I've used (JAX-RPC, Axis 1 and 2, but not XFire). The JAXB 2 databinding uses generics, which makes for a pleasant mapping of properties with a maxoccurs > 1. JAX-WS itself is reasonably well documented and provides a reasonably good API. The method and parameter annotations can get a bit out of hand in some cases - XML hell in annotation form. It usually isn't so bad.

One of the nice aspects of the JAX-WS stack is project Metro, which Sun co-developed with Microsoft and interoperates well with the web service support .NET 3.0, going so far as to implement MTOM in a workable fashion.
