this error is minor and does not have any impact on overall functionality of jbpm console - it is bug in application server with concurrent access to singleton ejb bean and was addressed in upcoming 6.2 version. Anyway application should be completely up and running.
Thank You Maciej,
In the demo configuration where can I change the bind ip-address, I think that has been the problem as it was listing on the internal ip-address by default. I did try to change it in the build.xml file bind address, which does seem to fix the address and now netstat shows it listening on that ip-address. The problem now I can only connect form the local machine and not any external hosts. I did check and there is no firewall enabled as I thought it was just the firewall blocking the port.
I can reply to my own thread to close it out, I now understand there is a new firewall inside of Fedora. Once I read-on on getting the ports to close I was able to get in from my remote machine. Thanks!
