Hi Henrik, Well, it seemed that RDF4J did not load the path to the template virtuoso.ttl. Then, I added the file virtuoso.ttl to the directory
core/repository/api/src/main/resources/org/eclipse/rdf4j/repository/config/ and the Virtuoso drivers to the pom.xml file for the compilation process. BTW, I modified the template because there was a bug (two semicolon were missing) Best, On Mon, Jun 26, 2017 at 11:16 AM, Henrik Schmidt <h...@informatik.uni-kiel.de> wrote: > Hi Adam, > > can you explain why your solution was necessary and it did work without > it for me ? > > Best > > Henrik > > Adam Sanchez schrieb am 23.06.2017 um 13:57: >> Hi Hugh, >> >> Finally I found my own solution.
