Dear Hugh,
I apologize, I sent you the version of the virtjdbc4.jar and not of the
virtjdbc3.jar that I am actually using and is the exact same version you
listed.
I believe I have the most recent versions of all the components.
Anything else I should check?
Thank you,
Paolo

Hi Paolo,
Looking at the version of your JDBC driver it seems quite old, as the latest
version is:
$ java -jar virtjdbc3.jar
OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 3.x [Build 3.62]
$
available for download from:
Hi Hugh,
I am running basically the code of that example, trimmed down to the ASK
(the full example run fine though).
The ASK in my case is simply to verify the existence of a graph
I am using
Virtuoso Open Source Edition (Row Store) (multi-threaded)
Version 6.1.8.3127-pthreads as of Jan 22 2014
I am trying to check for the existence of a graph and if I execute this
query in the Conductor
ASK { GRAPH http://example.org/tests/graph/001 { ?s ?p ?o . } }
returns 'false' when the graph is not there.
However, if I run the same query with Jena and the Virtuoso Jena Provider I
always get back
Hi Paolo,
Have you tried the Example9 program which demonstrates the use of ASK queries
in the Jena Provider documentation at:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtJenaProvider
Also, please confirm the version of the Virtuoso server, Jena Provider , Jena
