    Hi Anup,

    From the error, it looks like there is some issue with JCo.

    Check that the JCo destination is created on the 7.1 server (steps little different than in older releases) with the same name as you have given at the time of Import of Adaptive RFC model in NWDS.

    Try restarting the server, then deploy new archive & run the application.

    Kind Regards,

    Nitin

    Hi Anup,

    It seems I overlooked the note & went into the below exception details.

    I feel reading somewhere that NullPointerException (or ClassCastException) for the classes which are available is due to corruption of the WD metadata (may be there is a SAP Note)

    Kindly close the NWDS, delete the config folder in your workspace (Do Not Delete the .ini file) and restart the IDE (better to start in a fresh workspace).

    Hope this works for you.

    Kind Regards,

    Nitin
