  • SmartClient installation on JBoss Gatein 3.5

    Hi,

    I am using evaluation version of SmartGWT and trying to deploy it on JBoss Gatein 3.5 Final version.

    The app works fine when run from eclipse in development mode. However, when it is deployed on JBoss Gatein server it gives following error:
