I downloaded the EME 1.2.1 and tried for hands-on on my laptop. The Protocol Proxy failed to start on port 80. I am not sure what service is listening on my laptop on port 80. “netstat –an” showed the port was in listen mode. I updated the Tomcat’s server.xml and changed the port from 80 to 8080. The Protocol Proxy started up fine.

Next, I started up the EME and logged in. So far so good. However, things started failing when I created a trading partner with HTTP 500 error. I believe this is due to the fact EME is failing to communicate to Protocol Proxy on port 8080.

How to correct?
