I was performing a Sun Java Messaging Server migration in the Philippines for a government agency.
As the Communications Express (UWC) was still running on port 82 during the new Messaging Server installation, I need to use port 80 temporarily for the new UWC instance.
When the migration was performed and the old UWC was brought down, the following is what I did to configure the new UWC instance running on Port 80 to point to Port 82.
# vi /var/opt/SUNWuwc/WEB-INF/config/uwcauth.properties
Then I log in to the Sun Web Server Administration Console to change the Port from 80 to 82.
The last step is to redeploy the web application again (by clicking on the Deployment Pending hyperlink).
Short and sweet!
