Hi Babis, We have an Inference Graph example (VirtuosoSPARQLExample13) in the Jena documentation at http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtJenaProvider?#Testing , does this run for you ?
Also please confirm the versions of the components being used with the following commands: virtuoso-t -? java -jar virt_jena.jar java -jar virtjdbc3.jar Best Regards Hugh Williams Professional Services OpenLink Software Web: http://www.openlinksw.com Support: http://support.openlinksw.com Forums: http://boards.openlinksw.com/support Twitter: http://twitter.com/OpenLink On 18 Aug 2011, at 11:22, Babis Doulaverakis wrote: > Hello, > > I am trying to use the Virtuoso-Jena provider to make an Inference Graph in > Jena using Virtuoso as a RDF backend but an exception is thrown.
