Null Pointer exeption during Stanbol Autotagging #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Installed Alfresco module and share module
2. Setup Stanbol Server and configured Modules to use specific Stanbol server
3. Try to Autotag Document

The Webscripts say "Document successfully Autotagged", but the semantic tags 
are not available. The tomact logfile shows me some Nullpointer error like the 
one below.

I'm using Alfresco 4.2d with Tomcat 7.0 and Linux.

Has anybody discovered a similar error? How can I proceed with debugging?

Best regards..
Sebastian
