WAS 6.30 - First Web Dynpro application


I have just installed the Evaluation Version of WAS6.30 with the NetWeaver Developer Studio and I'm trying to go through the first tutorial, the WelcomeApplication. I can create the application, build the project without problems but when it comes to deploying and running the application the browser starts and I can not see anything. There is an error on the page:

          Line: 63

          Char: 303

          Error: Invalid argument

          Code: 0

          URL: http://a113972:50000/webdynpro/dispatcher/local/Welcome/WelcomeApplication

                  The dispatcher, the J2EE engine and the SDM are running and I have the following settings in Preferences:

                  <<SAP J2EE Engine>>

                  Remote Installation (unchecked) - a113972 / 3601

                  Local Installation (checked) - C11 / 0 / 1

                  <<Software Deployment Manager>>

                  localhost / 50018 and successful connection test

                  I have also installed the MS Loopback Adapter with the suggested settings, and made sure that my hosts file does have an entry with the following:


                  I would appreciate if someone could point out what else is missing.

                  Thank you,

                    I'm sorry, I forgot to mention that http://a113972:50000 works, it comes back with the J2EE start page.

                    Also, just out of curiousity I downloaded the WelcomeApplication tutorial ( and opened it as a new project, rebuilt it, deployed it and everything is OK. So, what did I miss when I built the project step by step based on the Developers' Guide?

                    Any help would be much appreciated.

                    Hello Gabor,

                    it is difficult to know what went wrong without looking at the code. Sometimes a blank in the jsp code can screw things up without to get any message from the compiler. You may want to check this?
