Server 'active' but not loading on port 80. authbind possibly not working?

[Joseph]

Quick question. I have simply changed the '18080' to '80' in the init.d file and conf/server.xml  files. When i run the command 'service webanno status' it says my server is active (displays it in the same way as when it is working on port 18080), however, it doesn't show up in my browser when using: http://localhost/webanno. 

My catalina.out file says:

At the bottom of the log file it says 'webanno.war has finished in XXXXms', and 'INFO: server startup in XXXXms', suggesting it has loaded. I assume it is working behind the scenes, but can't be accessed via a port. Is it possible authbind isn't working properly? It also says 'address already in use' but I have no other servers running....

Thanks,

J

Well, apparently you have. Try running "netstat -tnlp" as root to see which processes are running on which ports. That should help you finding out why port 80 is blocked.
