      i dont know much of doing JSP..but have done this thing using Java..& this ERROR is very common..

      what i got thrugh ur code is that u are Making a DataBase Connection

      in this case when u are doing


      Code:
      while (colIterator.hasNext()) {
                u = (userForm)colIterator.next();
                String name=u.getName();
                String pwd=u.getPwd();
      this While statements Throws an Exception which in Java we can clear up with a Try- Catch Block..

      so i think u also need to do the same thing..but dont know how this is done in JSP...

      Take care..
      Cheerz!!!

          A NoClassDefFound Exception is thrown if a class is referenced with Java’s “new” operator (i.e. static loading) but the runtime system cannot find the referenced class.

          So I think your system is not able to find userForm class. I don't know much about struts framework, as I havn't worked on it, but I think you need to check out for the entry of userForm in your struts-config.xml file. (or may be any other setting).
