Hi Hoan,
Virtuoso has a JDBC driver so you can make as many connections as you want from
Java.
You asked this question regarding materialisation of RDFViews as physical
triples last month and the following tip was created as a result:
How can I create multiple connection to virtuoso from java? The scenario is
that I want to take a query result from RDF Graph views to be an input of
another physical graph. While virtuoso still does not support join rdf views
and physical graph so I can not put into one query.Any help?
Thanks.
