I am trying to deploy jbpm console and human task on Amazon EC. And there are several issue that I didn't catch when do the same step on my local PC. I build from source jbpm console client, server and human task wars. Changes that I made: 1. Replace persistence properties to work with MySQL. 2. Make sure that drools-*, knowledge-* and jbpm-* jars have the same version in all WARs. 3. Disable to use default evaluation process example. When I logged on to console using krisv/krisv and click on the Processes tab I got the next error: Hi.   I am trying to deploy jbpm console and human task on Amazon EC.
