Hi, I've downloaded the jbpm-5.3.0.Final-installer-full.zip and have got it working fine on my localhost.

I'm now trying to deploy it on an Amazon EC2 Centos instance and having no end of problems.  Amazon EC2 is a NAT'd server, so the actual IP on the server is different to the IP accessible from the Internet.

I'm trying to get the JBPM-console working correctly. I can see the console and launch processes, but tasks never arrive for the users. Keep getting stack traces which I can share if required.

So, the things I've tried on the Final installer are:

1)  Modify build.xml so that the bind address is the NAT'd IP address on the server's primary interface.
2)  In standalone.xml I've changed the management and public addresses from localhost to (Listen on all interfaces)
3)  Then 'ant install.demo'  to push the changes

It is now accessible from the Internet and I can access drools-guvnor, jbpm-console etc.
Here are the listening ports:
[root at myinst2 data]# lsof -i -Pn|grep java|grep -i listen
java     29475        root    7r  IPv4 1416067      0t0  TCP *:9092 (LISTEN)
java     29536        root  161u  IPv4 1416083      0t0  TCP *:9999 (LISTEN)
java     29536        root  163u  IPv4 1416084      0t0  TCP (LISTEN)
java     29536        root  166u  IPv4 1416085      0t0  TCP *:9990 (LISTEN)
java     29536        root  170u  IPv4 1416087      0t0  TCP *:1090 (LISTEN)
java     29536        root  171u  IPv4 1416088      0t0  TCP *:1091 (LISTEN)
java     29536        root  799u  IPv4 1416111      0t0  TCP (LISTEN)

So what is the subtle difference between having a working JBPM-console on localhost vs live on the Internet?  
I tried modifying the war file for the jbpm-console as advised here:  http://docs.jboss.org/jbpm/v5.3/userguide/ch.console.html#d0e4624 http://docs.jboss.org/jbpm/v5.3/userguide/ch.console.html#d0e4624  but then JBPM-console wouldn't even start. All I did was add the NAT'd IP address for bpm.console.server.host=<NAT IP address> in WEB-INF/classes/jbpm.console.properties.

Any advice on how to deploy JBPM 5.3 on a Cloud server (using NAT - like they all do) would be appreciated.
