I cannot run Tomcat from Eclipse. It says that there?s other process that is running on port 8080, but I don?t know what is the process, and how to stop it from the Services manger in Windows. So here?s how you can kill and find out what is that process: To find out what PID 8080 was (hopefully not a trojan) I typed tasklist /FI ?PID eq 8080″ taskkill /F /PID 2600
0netstat -a -o -n | grep 8080 -
0netstat -lnptu
