[protege-discussion] WebProtege ontology loading failure

Hello,

I have a problem concerning WebProtege. I am executing WebProtege from
the Eclipse IDE (in both hosted and web mode) and everything works
perfectly fine until I try to load an ontology where I get the error
"Load project Pizza failed. Message: The call failed on the server;
see server log for details". You can see the errors in the end of my
e-mail. I have tried both absolute and relative (to Protege server)
paths for the ontologies in the metaproject with no luck. I have also
made sure that the metaproject files are identical in both places.

I would really be grateful if you could help me out. Thanks you very
much for your help and effort.

Best regards,
Manolis Platakis
