[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

Do you have any idea what i'm doing wrong?

Re: [Bigdata-developers] Blazegraph custom function problem

[Bryan T. <br...@sy...>]

Andreas,

The basic issue here is that the custom function registrations are not
sticky.  They need to be made within the server each time the server
starts.  For applications that embed blazegraph, you just do this from your
code when you start the server and before submitting any queries.  For the
server version, you do this by extending the
BigdataRDFServletContextListener and specifying your version of that class
(which must extend ours) in web.xml.  Your version just overrides
contextInitialized().

Igor is going to update the documentation to further clarify this as it has
lead to some confusion recently.

Thanks,
Bryan

Re: [Bigdata-developers] Blazegraph custom function problem

[Brad B. <be...@sy...>]

I've also updated   We've updated
https://jira.blazegraph.com/browse/BLZG-1485 with a work-around and will
add a new example.

For now you can either try the workaround in the ticket for the
NanoSparqlServer or your same code but using Blazegraph embedded such as
with
https://github.com/SYSTAP/blazegraph-samples/tree/master/sample-sesame-embedded
.

Let us know how it works out.

Thanks, --Brad

Are you calling that from client code?  It needs to be called on the
server, usually when the server is initialized (see
BigdataRDFServletContextListener::contextInitialized).
