We are trying to run the Struts example application under WebSphere 3.5.3 but get the following exception. Any ideas of what this means or where to go from here?
Thanks Error 500 An error has occured while processing request:http://localhost/struts/editRegistration.do Message: Server caught unhandled exception from servlet [action]: Server caught unhandled
