Re: [Virtuoso-devel] Virtuoso Bug?

Hi Steve,

What is:

1. The version for the Virtuoso server being used which can be obtained by running the following command from the bin directory of your Virtuoso installation:

	./virtuoso-t -?

2. What is the version of the Virtuoso RDF4J Provider being used which can be obtained with the command:

	java -jar virt_rdf4j.jar

3. Does the query run when executed against the Virtuoso /sparql endpoint ie http:/hostname:portno/sparql  or if run directly via the Virtuoso “isql” command line tool ?

Best Regards
Hugh Williams
