Jetty Startup Fails - Address in Use

问题:

I recently tried jetty on Amazon Ec2; when I try to start; I get 'Address already in use' error.

I am certain that no other servers are running on the this system.

I even try changing the ports to something other than 8080 to 8090

Still the same thing.

Here is the stacktrace. Any ideas how to solve?

You probably need to kill the process. Run ps -ef|grep jetty to get the process number, then kill it. Make sure you kill the process that is running the app server (859 was the process number on my machine).

$ ps -ef|grep jetty

Check that you don't have jetty-ssl.xml referenced twice.

I had this problem when I provided the start.jar with my own config, but had left the start.ini in the jetty root folder. That made some extra test-stuff be deployed that I hadn't indented. Removing the start.ini file from the Jetty directory solved the problem.
