1. First you need to check which two processes running on same port number 8080 (for tomcat). First, identify which Process is binding the desired port by running this from the Command Prompt: You can use 

netstat -o -n -a | findstr 8080

 

to find the PID and check what process it is.
You should get an output like this.

2. Next, use the ProcessID (value in the last column) to kill the process which is holding the same port:

taskkill /F /PID 7844
