Hi Stefan,
Thanks for the response. It is a regular WebObjects Application but you can select on the New WebObjects Project Wizard on the "Add WebServices support" Screen which is the 6th screen for me. If I remove the line
"WOWebServiceRegistrar.registerWebService(com.dd.wstest.WS.class, false);"
I get a perfectly working Webobjects-App.
cheers
