Hi Hugh,
I modified the VirtuosoQueryExecution.java file. That appears to remove the
extra stuff being prepended to my query. Now my queries return data. I
modified the second constructor to now read:
public VirtuosoQueryExecution (String query, VirtGraph graph)
{
virt_graph = graph.getGraphName();
//modified this line:
virt_query = "sparql " + query;
virt_url = graph.getGraphUrl();
virt_pass = graph.getGraphPassword();
virt_user = graph.getGraphUser();
}
Just to be clear, is there a 64 bit version of the JDBC drivers? Is there
something else I need to change in my code?
Thanks,
Chuck
