Thread-topic: Problems executing OSLC4JBugzilla from the OSLC tutorial

Dear all,

I have been redirected from the Open Services for Lifecycle Collaboration
forum to this mailing list. Here's my problem:

I’m trying to follow the instruction in the appendix of the tutorial
(http://open-services.net/resources/tutorials/integrating-products-with-oslc/appendix-running-the-examples/).

When I execute the OSLC4JBugzilla Adapter, I get some Java errors on the console (see attachement).
Trying to access the service at 

    http://localhost:8080/OSLC4JBugzilla/services/catalog/singleton

results in the following response:

    HTTP ERROR: 503

    Problem accessing /OSLC4JBugzilla/services/catalog/singleton. Reason:

    Service Unavailable
    Powered by Jetty://

I tried to fix this problem using the tips given at

    http://open-services.net/forums/viewthread/77/

but they have not worked for me.

Does anyone have a clue what's wrong? Maybe even the Java environment?

Best regards

    Marc.
