Postgresql database created and populated according to simplified Wortschatz example,

Start jetty,
/Sparqlify/sparqlify-core$ ./bin/sparqlify -h localhost -u meteo -p meteo -d meteo -m ./Wortschatz.sparqlify -n 1000 -t 30 2>&1 | tee out.log

Navigate to,
http://localhost:7531/sparql

$ cat out.log

Most likely this issue is no longer relevant to the current sparql server.
