Can anyone determine where the problem is? I also had problems trying to create a GWT application and a Python App Engine project.

Possible duplicate: DevServer crashes after upgrading to java 6u31

However, this problem is apparently documented (with a solution) here: http://code.google.com/p/googleappengine/issues/detail?id=6928

From the site:

Workaround - Run GAE with the following JVM parameter:
-Dappengine.user.timezone = UTC

(use eclipse to go to "run configuration", on the "Arguments" tab add "-Dappengine.user.timezone = UTC" to the VM argument string. Using maven-gae-plugin add -Dappengine.user. timezone = UTC to the configuration plugin). Good luck, and hopefully Google will soon support the JDK u31.

In this article, my problem with GWT was resolved: The fix failed to restore the previous time Zone to GWT .
