JBoss -> GlassFish: Packaging of classes at the top level in a WAR

In JBoss, the classes can be packaged at the top level in the war file. The ear/war will fail verification by GlassFish verifier. So, move the classes to to WEB-INF/classes directory.

Example:

// JBoss Packaging
    app.ear
    ... app.war
        ... ToDoBean.class

   // GlassFish Packaging
    app.ear
    ... app.war
        ... WEB-INF/classes/ToDoBean.class
