The JAXWS project in the WebTools incubator has made its way into the light of day on the latest and greatest 3.1M5 release update site. Point your Eclipse update site manager to http://download.eclipse.org/webtools/milestones to get the plug-ins. One thing to note is that while this release uses the most recent I-build of the WTP frameworks, the code is intended to work with the Eclipse 3.4.1 release too.
When you access the update site, you should see the CXF Web Services (Incubator) feature available in the site listing.
Thanks to David Williams for setting up the build and Shane Clarke for the awesome code construction!
