Exception occured in J2EEC Phase

[AFinlo...@googlemail.com]

Hi I am trying to use GWT and J2EE in netbeans version 6.
I am able to deploy and run my server side ebj, but when I try to add
the GWT frame work to the web project, and then try deploying the
application again the following exception appears.

- Thanks in advance.
