Hi, I am making a maven based GAE project. It's a service that is supposed to serve some data to its clients. The project works perfectly on the local machine, but gives the NoClassDefFoundError when deployed to GAE. Here's the complete StackTrace:

) As you can see in the Platform.class.PNG screenshot, the class is present (At least at compile time. I don't know how it vanishes at runtime?), The dependencies are downloaded from the public Maven repo. Just one external JAR is included from my local repo using: <dependency> <groupId>com.mywork</groupId> <artifactId>emfjson</artifactId> <version>0.4.1</version> <scope>compile</scope> </dependency> All these Maven dependencies including the external JAR are packaged with the WAR file (as seen in Dependencies.PNG). Where could the problem lie? I have spent days but still cannot find where the problem exists.
