Hi sjachym,
Adding export to WAR functionality to the Eclipse plugin has been reported
and is planned for inclusion in a future release (see Issue # linked below).
This means that worst case, you can at least generate the .war file and add
it to your EAR project.
Issue #3584:
Hy, i try GWT 1.6, but, because my new project is Web Application
Project (created by Google Eclipse Plugin) instead of Dynamic Web
Project, my EAR not contain the .war (there is only include the .jar)
How to publish an EAR including a Web Application Project (Google) ?
