While working on a WIX project, I encountered an issue with my REST-based web service not starting. After debugging, I discovered that the designated port was already occupied by another application. To troubleshoot, I employed the Java Socket class to check port usage. By initializing a Socket instance with the local host and the specified port, I could determine the availability of the port, which helped clarify the cause of my service startup failure.
To check if a specific port is in use, creating a new Socket instance with the local host and desired port can effectively confirm port availability.
The Java Socket class provides a simple way to test if a port is being used on the local machine, allowing developers to troubleshoot application issues.
