[Bigdata-developers] Blazegraph custom function problem

[andreas81_81 <and...@o2...>]

Hi all,
I have blazegraph 1.5.2 running on my machine (Windows, bundled version) and I've written sample java application (based on the information on blazegraph wiki page) but it does not work. My custom function is exactly the same as provied on the page (security filter), the function is registered, the query seems to be correct ... but blazegraph is unable to find the registered function. I'm running blazegraph with the following command:
java -classpath d:\dev\Blazegraph\org.lhasalimited.blazegraph\target\classes\ -server -Xmx4g -jar bigdata-bundled.jar
(the directory contains class with my custom function). After running a sample application which calls:
FunctionRegistry.Factory factory = new MyFunctionFactory();
URI myFunctionURI = new URIImpl("https://www.ebi.ac.uk/chembl/chox#validate");
FunctionRegistry.add(myFunctionURI, factory);
The application throws:
java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: org.openrdf.query.QueryEvaluationException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.Exception: task=ChunkTask{query=2125bb5c-9355-4482-8b52-c3036fe60744,bopId=1,partitionId=-1,sinkId=3,altSinkId=null}, cause=java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.UnsupportedOperationException: unknown function: https://www.ebi.ac.uk/chembl/chox#validate
