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?

Have you already tried accessing the server in your web browser on port
3030 to see if it responds?

Hi there, I try to start Fuseki with the following instructions
FusekiServer server = FusekiServer.create()
.port(3030)
.add("/ds", dataset)
.build();
System.out.println("Fuseki is starting on port: " +
server.getHttpPort());
server.start();
The server starts on port 3030 but hangs on. The dataset is fine, and
the port is available. The debug logs include

Any suggestions what might be wrong? The help will be greatly
appreciated.
Thank you so much!
