    Posted Mon January 28, 2013 08:46 AM
    Hello everyone,

    Well it is a class loading issue. you can do a couple of simple and themore complex things.


    1. Change class loader from parent first to parent last may help identify the class loading conflict.

    2. Check the class loader viewer in console

    3. Put on tracing to see more information

    4. Check stdError.log

    5. Make sure that the EAR has been verified for that JDK vesion.
