Hi,

I want to use Maven integration in my GXT project. Therefor i followed the tutorial "GWT GXT and Maven howto" (http://www.extjs.com/learn/Tutorial:GWT_GXT_and_Maven_howto).

When I run my project using "mvn gwt:run" the GWT hosted browser starts. But when I want to use the launch configuration I have created using "mvn gwt:eclipse" I get the following errors:

- Right click on the launch configuration file -> Run as -> Web Application: java.lang.NoClassDefFoundError: com/google/appengine/tools/development/DevAppServerMain

- When I open the Run configuration it get the following error message: " Project does not use GWT or GAE"

Can someone tell me what I'm doing wrong?
Thanks in advance!
