Hi Andy, thank you for the quick response. I am running Windows and the latest
Fuseki and Jena available for download 5.1.0 version.
Thank you!
Regards, Neli.

If you find there is a Fuseki alkready on 3030, it may be because Fuseki
has background threads so just returning from application "main" does
not exit the JVM.
Either
Systrem.exit(0)
or
server.start();
try {
....
} finally { server.stop(); }
For general information
- which OS are you running on?
- which version of Fuseki is this?
