I recently installed LiveCycle ES4 on a new computer, and came across an issue I’ve had in the past but have not blogged about. The turnkey installation option installs all required LiveCycle components, including JBoss. A default JBoss installation uses port 8080 which I know was free on the machine, but when installing I received the error:
Turnkey Install Verification Error:
The following port(s) are required for the Turnkey JBoss instance, but are still in use: 8080
After confirming with netstat that the port was indeed not in use, I remembered that antivirus software can sometimes interfere with the installation process. By temporarily disabling the antivirus software and reattempting the installation, port 8080 was available, and I could continue the installation.
Hopefully this will save someone else some time in the future!
