Just relax - custom property functions work well in Fuseki 2. (which
is presumably something along the lines of what Trevor wants to add).
I tested a custom function with Fuseki 2 WAR deployed in Tomcat 7:
PREFIX arq: <java:arq.examples.propertyfunction.>
SELECT ?s ?name WHERE { ?s arq:localname ?name }
works perfectly.
I added localname.jar to WEB-INF/lib/ as Trevor suggests:
sudo jar -uf /var/lib/tomcat7/webapps/fuseki.war WEB-INF/lib/localname.jar
(You have to place the JAR in an empty subfolder WEB-INF/lib/first)
Tomcat should restart the application automatically when the .war is updated.
(I made localname.jar from the jena-arq/src-examples. I had to do the
last bit old-skool with javac and jar as there was no pom.xml for the
examples :( )
# fuseki dist
Installing custom JARs to fuseki 1 or in the Fuseki 2
jena-fuseki2/jena-fuseki-dist distribution seems to be a bit trickier,
as you have to edit the launcher scripts fuseki-server or
fuseki-server.bat to modify the java -classpath.
(Even then I could not get this to work, but I didn't try very hard).
