Unable to open debugger port in IntelliJ IDEA

Question

I have a problem that I can not set up my application in debug mode with IntelliJ IDE, but run mode is OK.

My OS is Windows 7, IDE is IntelliJ IDEA, web container is Tom

Answer 1

This happens when you have application running on the same port number. One way to do this by killing the process forcefully. Open command prompt as an admin. Run command 'taskkill /IM "java.exe" /F'. This worked for me in Windows. Let me know if this works.
