How to view which apps are using a port?

[iluvdeal]

I'm trying to run a web server (tomcat) but keep getting the message:

java.net.BindException: Address in use: JVM_Bind

So apparently port 8080 is in use. Is there a way I can view which app is using it? It worked fine before. I do have some apps (irc, ftp) downloading in the background but in the config I don't see 8080 anywhere so I don't know if they are the ones using it. Thanks!

/usr/sbin/lsof | grep 8080

As root:

netstat --inet -ap | grep LISTEN
