    classloading problems of a custom principal

    Marco Zanker Newbie

      I'm getting the following error if I'm trying to call a server method of my application.

      The custom principal class is in a simple jar-file. This jar-file is placed in the ear module (lib directory).

      During deployment the classes in this package are found by the deployer, because I didn't get any errors and some of the classes in this package are also part of

      the interfaces in this module.

       

      This method is working fine in jboss 5.0 because, I haven't any problems with this solution.

      If I'm deploying the jar-file as a simple jar file in the deployment directory of jb6 or if I copy the simple jar file in the default/lib directory it works.

      But this solution is not good, because the jar files are part of the application und should'nt be accessable by any other applications.

      Is it a bug or any ideas deploying the principal class in a application context in jb6.

      Thx and best regards,

      Marco
