jenkins slave on server with custom port

Question

I've installed jenkins on suse 12.1 and changed the port in the config to 8081

/etc/sysconfig/jenkins

JENKINS_PORT="8081"

The webinterface works without any problem on this port, but when I want to start the client with JNLP he gives me the standardport:

javaws http://192.168.1.137:8080/computer/192.168.1.190/slave-agent.jnlp

Now I tried to run it with the right port:

javaws http://192.168.1.137:8081/computer/192.168.1.190/slave-agent.jnlp

But after a short time I get an error:

java.io.FileNotFoundException: http://192.168.1.137:8080/jnlpJars/remoting.jar

He tries the wrong port. How can I change the port correctly?

Have you updated the URL via the configuration option under Manage Jenkins → Configure System → Jenkins URL?
