The method I mentionned does not rely on any low-level Virtuoso connection, nor wrapping it in a local Jena model. It just connects to any SPARQL WebService (also called a SPARQL endpoint) and sends the query as an HTTP parameter. It retrieve the result data as XML, and wraps it into a ResultSet object. You can then iterate the resultSet.
Please note that if your query is not a SELECT but a CONSTRUCT, the returned data is not wrapped in a ResultSet object but in a Model object 2011/12/8 aliki aliki <[email protected]>: > Thanks for the quick reply.
