Active Ports from DeviceLock will help with this.
Another option is tcpview from Sysinternals (Microsoft).
Also, if you know the name or ip of the device you are connecting to you can use netstat and look in the foreign address field for the host you are connecting to with the application.

The issue with netstat is that it does not show what application is using a particular port. tcpview is a good tool for this purpose in that it shows the service or program and what port(s) it uses.

Thanks, I was able to determine that the port utilized by Visual Composer is the same port utililized by the Java Application Server. I prefer tcpview over Active Ports.
Thanks again for the help.
