Hi,
When you are done with the file, you should close your manager.
I believe should do the trick:
public void endRDF() throws RDFHandlerException {
manager.close();
}
// NOTE: I don't know the specifics of RDFHandler, but it sounds like endRDF()
is the method called when the file handler is complete. ?
This way, the last triples inserted, but not committed, are committed.
Perhaps that is your problem? ... you are missing the tail end of your RDF file.
However, if you are simply calling a SPARQL query within the same thread then
the uncommitted triples should be visible to your code.
What are your thoughts on the matter?,
Marko.
