jetty eclipse plugin 问题

http://docs.codehaus.org/display/JETTY/Jetty+Documentation

Hi,

I'm trying to use Jetty to debug a Java Web application. I installed the JST plugin like described on this page: http://docs.codehaus.org/display/JETTY/Web+Tooling+Support

Now I have a basic web application (tapestry5 archetype or eclipse default web application template) and I add it to Jetty server. Then I try to start Jetty and I get an error:

Publishing to Jetty6.x... (Time of error......)
Reason:
java.lang.NullPointerException
Could not publish to the server.

In the console, I have:

2008-03-25 18:31:58.627::INFO: Logging to STDERR via org.mortbay.log.StdErrLog
2008-03-25 18:31:58.783::INFO: jetty-6.1.8

2008-03-25 18:31:58.861::INFO: Started SelectChannelConnector@127.0.0.1:8080

And in Eclipse log file, I have:

!ENTRY org.eclipse.wst.server.core 4 0 2008-03-25 18:32:00.187
!MESSAGE Could not publish to the server.

This error is cause by Eclipse 3.3.2 and the plugin works ok on 3.3.0. If you can get hold of the Europa 'fall' release it will work for you. This issue is also logged as JETTY-577.

This is fixed with WST 2.0.2 which is available on the Eclipse update site. I searched for new features to install and drilled into patches and installed all the WST and JST 2.0.2 patches. It's now working for me. Looks like they found this on the day of the winter release... https://bugs.eclipse.org/bugs/show_bug.cgi?id=219627.

By the way, I'm also working on a variation of the Jetty eclipse plugin that runs the war exploded, and am reasonably confident this will work in most cases.

Sorry, I searched for updates to existing features – oops. Also, this affects all generic server plugins including JBoss and Glassfish.
