At first I had some problems but after executing rmiregistry 1099 the
server started successfully.

I have already added the user and the password. All the available
projects show up in the list when executing WebProtege.

I 'll do that on Monday and get back to you (it's the dawn of Saturday
in Greece :-)).

I will also zip and e-mail the logs.

Thanks again!
