[Andy Seaborne]

Paul,

How are you running your code in the Fuseki server?

Thanks, Bruno for your response.  Yeah, I've looked at them.  They seem to
work ok when the context of the model is known.  But not sure how to
integrate it with fuseki.  It might be because I am setting the model
through configuration.  Cant find many examples though. : (

Hi Paul,

I haven't used listeners with Jena. Have you had a look at the docs
already?

I am new to this and struggling to find any information relating to
configuring fuseki so that I can listen to the events when inserting into
the triple store.  I have the following code which I can see is running
from the logs.   But the listener doesn't seem to be triggered.  Any help
would be appreciated.

public class Listener {

     public static void init() {
         System.err.println("Starting process...");
         Model m = ModelFactory.createDefaultModel();

         m.register(new ChangedListener() {
             @Override
             public void addedStatement(Statement statement) {
                 System.err.println("New statement added: " + statement);
             }
             @Override
             public void removedStatement(Statement statement) {
                 System.err.println("Statement removed: " + statement);
             }
         });

         System.err.println("Registered ChangedListener 0...");

}
