Hi, using the Virtuoso Sesame HTTP Repository following this tutorial: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository At the point where I like to add a new Virtuoso repository via openrdf-workbench I do get a Nullpointer exception.
I'm using virtuoso open source version (Version: 06.01.3127), openrdf in the newest version (2.7.9), tomcat7 catalina.out gives the following information: > Jan 21, 2014 11:45:07 AM
