Hi Martin,
I don't see anything Virtuoso specific in the logs provided. Was the
openrdf-workbench working prior to making the changes to for Virtuoso ie could
you create a repository for one of the defaults support for Sesame Native, In
memory, MySQL, Postgres etc ?
What is the exact version of the Virtuoso Server, Sesame Provider and JDBC
Driver being used ?
virtuoso-t -?
java -jar virt_sesame2.jar
java -jar virtjdbc4.jar
Best Regards
Hugh Williams
