Are you getting any errors in your console log? Do you see two lines that looks like this:
2009-11-20 12:03:28,485 INFO [Http11Protocol] (main) Starting Coyote HTTP/1.1 on http-127.0.0.1-8080
2009-11-20 12:03:28,516 INFO [AjpProtocol] (main) Starting Coyote AJP/1.3 on ajp-127.0.0.1-8009
They should appear right before the "started in xxx seconds" message.
What OS are you using? And which version of JBoss AS? See if this helps:
Check if any other application is configured to the same port.
Like your proxy or any other web application.
We again had this issue, it happened 3 times in a year on 3 different machines.
Jboss port 8080 which was listening from a year suddenly stops listening(we do restart instances atleat once a month), of course restart of the instace will resolve the issue.
These servers only have Jboss, and no other services are installed which might try to occupy 8080 port.
Do any one have any idea what might be the root cause?
