Hi Moritz, Could you try the following: - In your project properties, could you see what the App Engine SDK is set to (right-click project > Properties > Google > App Engine). Does it show an error on this page? If you click the Configure SDKs button, what is the path for the SDK? - In your project properties, can you go to Java Build Path , then Libraries tab, and see if there are any leftover JARs on your classpath? If there are, could you take a screenshot of that dialog (hopefully tall enough so all the entries are visible)?
