Debugging a query is more efficient if you print the query to the
command line first, and put it in the Virtuoso web interface - I suppose
that you use the offical DBpedia endpoint.
By the way, it's not clear why you call toString() on "x" .
I think you need to provide more information, before anyone can answer
your questions.
What is the actual endpoint or dataset you are executing on? What is
the code executing the query?

at the end I display it
System.out.println(soln.getResource("x".toString()));
*But it displays nothing (no error message but no output)*
*What is the problem in the code.*
