I was looking at IntelliJ 7.0 new features list and noticed that JAXB/WS support is there, so I gave it a try.

First when you create a project, it asks for the toolkit that you want to use. GlassFish/JAX-WS combo is the default.

IDEA now comes with the built-in sun-jaxws.xml editor with auto-completion and what not.

You can also create a new web service (which creates a skeleton class and updates necessary entries in sun-jaxws.xml), or create a client (which invokes wsimport internally.)

It is IntelliJ's first shot at web service support and it shows — The UI is crude and there are some rough edges. But nevertheless it's great that web service support is spreading. (And I should also note that all in all NetBeans web service support is much better)
