Hi Andra,

What  version and build date of the following components are being used:

1. The Virtuoso Server :

        virtuoso-t -?

2. The Virtuoso JDBC Driver

        java -cp virtjdbc3.jar virtuoso.jdbc3.Driver

3. The Virtuoso Jena Provider:

        java -jar virt_jena.jar
or
        java -jar virt_jena2.jar

depending on which provider you are using for the Jena Framework version being 
used ...

Best Regards
Hugh Williams
