Hello all,

I'm new to OGSA-DAI and I have a problem when creating my own resource. This
resource wants to access an OWL ontology as a resource. The problem I have
is when I try to deploy it in a Globus container because I get an exception
like the one that is at the end of the email. I've been looking at Section
17 of the OGSA-Dai's user manual
(http://www.ogsadai.org.uk/documentation/ogsadai3.0/ogsadai3.0-gt/ServerConf
igFilesCH.html) and I think I've configured everything properly. I also
attach the resource file I created.

Thanks a lot!

Carlos
