Hi all,
I have followed a training at the SAP Training Centre in Belgium, and back from this training I installed the NetWeaver CE 7.1 on my computer.
I have followed the "Developing your first Web Dynpro application" tutorial step-by-step, I have compiled it and deployed it on the server, but I'm having trouble when trying to run this "Welcome" project: I get an error:
500 Internal Server Error
SAP NetWeaver Application Server/Java AS

Any idea of what causes this problem?
