Re: [Virtuoso-users] Blank node usage via Sesame
Hi Timo,
This is odd as the version you are getting from CVS which works is data Feb
2010, which was the date of Virtuoso 6.1.0 open source release and would
explain why you are not getting the version information. The one you downloaded
and the one from the Virtuoso 6.1.2 open source release which do give the
version information as expected are the same, but you are saying these are
problematic for you. We shall look into this and report back ...

Hi Hugh.
The jar in CVS (virt_sesame3.jar) works perfectly well, and the sources
seem fine as well, but the jar on the Download page causes the Exception.
It seems that for some reason the used ValueFactory doesn't contain a
BNodeFactory.

Re: [Virtuoso-users] Blank node usage via Sesame
Hi Hugh.
I used the Sesame 3 adapter and JDBC 4 driver from this page :
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VOSDownload
The Sesame dependencies I use are from the 3.0-alpha-1 version via this
Maven repository :
http://repo.aduna-software.org/maven2/releases
Are the sources for the Virtuoso Sesame 3 adapter available for
download? This way I could debug the problem more easily.
Best regards
Timo Westkämper.
Hi Timo,
Yes, Virtuoso does support blank nodes as does the Virtuoso Sesame Provider.
How exactly are you compiling and attempting to run the application containing
the code snippet you provided below ?
Best Regards

Blank nodes are not supported with OpenLink Virtuoso?
