    the classpath did look like this:

    I then added TankDiskServer/build/TankDiskServer.woa/Contents/
    Resources/Java manually as classpath variable like this:

    but that did not help the cause. Btw, the Maven Classpath Container
    is provided by the Q4E plugin: http://code.google.com/p/q4e/ http://
    q4e.googlecode.com/svn/trunk/updatesite/ if that is of any importance
