bryanthompson added a comment - 10/Sep/15 2:51 PM Do this for the embedded use case. Note that for the server you would have to hook the BigdataRDFServletContextListener.contextInitialized() method by overriding web.xml. Please link the new example and information about how to hook the BigdataRDFServletContextListener to the CustomFunctions wiki page.

Brad Bebee added a comment - 14/Sep/15 1:09 PM There are two modes for this embedded and with the NanoSparqlServer (NSS). The current Wiki instructions capture the Embedded. For the NSS, you must override the BigdataRDFContextListener contextInitialized method to add the function registry. Then the web.xml must be updated to use the overridden context listener in the web.xml listener. MyBigdataRDFContextListener extends BigdataRDFContextListener { contextInitialized( final ServletContextEvent e) { super .contextInitialized(e); URI myFunctionURI = new URIImpl( "http: //www.example.com/validate" ); FunctionRegistry.add(myFunctionURI, myFactory); } } web.xml update <listener> <listener-class>MyBigdataRDFServletContextListener</listener-class> </listener> It should be possible to do this in the executable jar using the jetty overrideWeb descriptor. This needs to be tested and validated. java -cp /path/to/my/classes -server -Xmx4g -Djetty.overrideDescriptor=/path/to/my/updated/web.xml -jar bigdata-bundled.jar

Brad Bebee added a comment - 14/Sep/15 1:41 PM Thanks. I've updated the Wiki with a link to this ticket for the NanoSparqlServer instance: https://wiki.blazegraph.com/wiki/index.php/CustomFunction .

Brad Bebee added a comment - 22/Sep/15 2:04 PM Initial embedded tests look OK. Please add a unit test and non-embedded example. https://github.com/SYSTAP/blazegraph-samples/pull/9#issuecomment-142298248
