Hudson will not start on Windows 7? JNLP slave agent listener started on TCP port

I'd like to setup Hudson to work with Ant. I 开发者_StackOverflowam using it for the first time, and when I try: java -jar hudson.war it starts doing something, but stops on the line:

INFO: JNLP slave agent listener started on TCP port 59204

I am running Windows 7, also the Java Web Start for hudson does not start.

Check if that port is actually reachable from the node. At the node you can try to telnet MASTER_IP 59204. The Hudson master machine may have a firewall that's currently blocking such access.

Hudson by default uses a random port number for each node to connect via JNLP. You can configure it to use a fixed port number. This works well if you have a firewall and only want to expose a limited number of ports for connection from the outside. Go to Manage Hudson and change TCP port for JNLP slave agents to a fixed port number.
