In troubleshooting an application installation issue on WIX, the author identified that an application service was unable to start due to a port number conflict with another application. To resolve this, they utilized the Socket Class in Java to check the status of the specified port. If the host parameter is null, the Socket defaults to the loopback address, allowing for local port validation, which is valuable in pinpointing the source of the conflict before attempting to restart the service.
Using the Socket Class in Java can help identify if a specific port is in use, which is crucial when resolving application startup issues.
When the host is set to null while using the Socket constructor, it defaults to the loopback address, effectively allowing local port checking.
