    D2RQ and D2R Server / Mailing Lists

    sourceforge.net | 3 months ago
    de.fuberlin.wiwiss.d2rq.D2RQException: No d2rq:Database defined in > the mapping (E1) Fine, that's what I expected. The d2r launcher launches an endpoint that > has one graph, that graph being a d2r graph initialised by the parameter. > It simply doesn't take a general JENA assembler as input. So lets have a look at the joseki that's inside d2r. The various files > in the joseki installation are not present. There is a joseki.jar in the > lib directory and that's it. Let's try launching joseki using the same method that rdfserver in the > full installation launches it. The launch in the full installation is: exec "$JAVA" $JAVA_ARGS -cp "$CP" $LOG joseki.rdfserver "$@" JAVA_ARGS is just "-server -Xmx1G" , which we can ignore. LOG is -Dlog4j.configuration=${LOGCONFIG}, which we can also ignore And CP will have to be all the lib files in the joseki directory $ CP=$(find lib -name *.jar | while read j ; do echo -n "$j:" ; done) $ java -cp $CP joseki.rdfserver simpleconfig.ttl Exception in thread "main" java.lang.NoClassDefFoundError: > org/mortbay/jetty/Connector
