This is embarrassing but I don't get it. I've configured $JENA_HOME and adjusted the PATH.
Now what classpath should I include when invoking the indexer? What I've tried so far: $ cd $JENA_HOME $ java -cp jena-spatial-3.8.0.jar jena.spatialindexer --desc=../fuseki-server/run/configuration/mm.ttl Error: Could not find or load main class jena.spatialindexer $ java -cp lib/*.jar jena.spatialindexer --desc=../fuseki-server/run/configuration/mm.ttl Error: Could not find or load main class lib.commons-cli-1.4.jar Thanks for your patience > Am 17.09.2018 um 11:38 schrieb Marco Neumann <marco.neum...@gmail.com>: > > yes correct, this looks good. now include the classpath during invocation > of the spatialindexer > > in addition it's always a good idea to properly configure jena along your > java runtime environment settings to avoid jdk / lib conflicts during > execution. > > https://jena.apache.org/documentation/tools/index.html > <https://jena.apache.org/documentation/tools/index.html> > > > > On Mon, Sep 17, 2018 at 10:28 AM Markus Neumann <mneum...@meteomatics.com > <mailto:mneum...@meteomatics.com>> > wrote: > >> 1.: what do you mean by indexer? >> Probably my biggest problem is, that I have no clue how to find out, where >> the jena.spatialindexer could be located except for asking here. >> >> Here is the content of the apache jena I downloaded: >> $ ls -lh ../apache-jena-3.8.0/lib >> total 17M >> -rw-r--r-- 1 process process 162K Oct 26 2017 collection-0.7.jar >> -rw-r--r-- 1 process process 53K Oct 26 2017 commons-cli-1.4.jar >> -rw-r--r-- 1 process process 328K Mar 5 2018 commons-codec-1.11.jar >> -rw-r--r-- 1 process process 576K Jun 25 09:59 commons-compress-1.17.jar >> -rw-r--r-- 1 process process 41K Mar 5 2018 commons-csv-1.5.jar >> -rw-r--r-- 1 process process 210K Mar 5 2018 commons-io-2.6.jar >> -rw-r--r-- 1 process process 425K Oct 26 2017 commons-lang3-3.4.jar >> -rw-r--r-- 1 process process 749K Jun 25 10:01 httpclient-4.5.5.jar >> -rw-r--r-- 1 process process 158K Jun 25 10:01 httpclient-cache-4.5.5.jar >> -rw-r--r-- 1 process process 318K Jun 25 10:01 httpcore-4.4.9.jar >> -rw-r--r-- 1 process process 65K Oct 26 2017 >> jackson-annotations-2.9.0.jar >> -rw-r--r-- 1 process process 315K Jun 25 10:01 jackson-core-2.9.5.jar >> -rw-r--r-- 1 process process 1.3M Jun 25 10:01 jackson-databind-2.9.5.jar >> -rw-r--r-- 1 process process 17K Oct 26 2017 jcl-over-slf4j-1.7.25.jar >> -rw-r--r-- 1 process process 2.9M Jun 25 11:03 jena-arq-3.8.0.jar >> -rw-r--r-- 1 process process 211K Jun 25 11:01 jena-base-3.8.0.jar >> -rw-r--r-- 1 process process 259K Jun 25 11:07 jena-cmds-3.8.0.jar >> -rw-r--r-- 1 process process 1.7M Jun 25 11:02 jena-core-3.8.0.jar >> -rw-r--r-- 1 process process 135K Jun 25 11:05 jena-dboe-base-3.8.0.jar >> -rw-r--r-- 1 process process 21K Jun 25 11:05 jena-dboe-index-3.8.0.jar >> -rw-r--r-- 1 process process 74K Jun 25 11:05 >> jena-dboe-transaction-3.8.0.jar >> -rw-r--r-- 1 process process 95K Jun 25 11:06 >> jena-dboe-trans-data-3.8.0.jar >> -rw-r--r-- 1 process process 135K Jun 25 11:01 jena-iri-3.8.0.jar >> -rw-r--r-- 1 process process 49K Jun 25 11:04 jena-rdfconnection-3.8.0.jar >> -rw-r--r-- 1 process process 2.8M Jun 25 11:01 jena-shaded-guava-3.8.0.jar >> -rw-r--r-- 1 process process 264K Jun 25 11:06 jena-tdb2-3.8.0.jar >> -rw-r--r-- 1 process process 512K Jun 25 11:04 jena-tdb-3.8.0.jar >> -rw-r--r-- 1 process process 1.6M Jun 25 10:01 jsonld-java-0.12.0.jar >> -rw-r--r-- 1 process process 232K Mar 5 2018 libthrift-0.10.0.jar >> -rw-r--r-- 1 process process 479K Oct 26 2017 log4j-1.2.17.jar >> -rw-r--r-- 1 process process 41K Oct 26 2017 slf4j-api-1.7.25.jar >> -rw-r--r-- 1 process process 12K Oct 26 2017 slf4j-log4j12-1.7.25.jar >> >> 2.: Turns out, I don't need the jts. after commenting out the affected >> lines, the server still runs fine.
