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
Hugh Williams

Hi.
I am using Sesame 3 with the JDBC 4 driver to access a Virtuoso database
and I am having problems creating blank nodes through it :
Repository repository = new
VirtuosoRepository("localhost:1111", "dba", "dba");
repository.initialize();
RepositoryConnection conn = repository.getConnection();
try{
conn.getValueFactory().createBNode();
}finally{
conn.close();
repository.shutDown();
}
This is the stacktrace I get :
java.lang.UnsupportedOperationException
at
org.openrdf.model.impl.ValueFactoryImpl.createBNode(ValueFactoryImpl.java:86)
...
Blank nodes are not supported with OpenLink Virtuoso?
