Sorry, now i understand your question. Do you want to acess any data in a
virtuoso graph? If yes, you can try this query:

Yes, but Jena doesn't accept the FROM clause inside the nested SELECT 
and that's what my question is about (probably to Andy).

Thanks

SELECT *
WHERE
{
        SERVICE <http://example.org:8890/sparql>
         {
               SELECT ?s ?id

               WHERE {
                      GRAPH ?g{?s a <http://ex.com/resource/Batch> .
                                       ?s <http://ex.com/resource/id> ?id .}
                }
     }

The following query is not valid (verified with Jena 2.7.3):

SELECT *
WHERE
{
    SERVICE <http://example.org:8890/sparql>
    {  SELECT *
        FROM <http://ex.com/base>
        WHERE
        {   ?s a <http://ex.com/resource/Batch> .
             ?s <http://ex.com/resource/id> ?id .
        }
    }
}

The parser complains about the FROM. Is this supposed to work, or are we
limited to using GRAPH instead?

Thanks
Holger
