My environment consists of jBPM 5.4, using Java 1.7, JBOSS AS 7.2, running on RHEL 5.8. All of the web components of jBPM 5.4 appear to be working fine in this environment. However, one thing I've noticed when I first start the apps server with the jBPM components, and then login to jbpm-console, that it takes approximately 3 minutes before any process definitions show up in the Process Overview tab. I have configred the the console to get these process definitions from both the file system and from Guvnor, defaultpackage.
Below is an excerpt from the server log. The line with FormDispatcherPlugin is where I logged into jbpm-console, and the line with "Loading process..." is where the application finally loaded the first bpmn file. This is over 3 minutes later,

I had seen a post somewhere that indicated this should take maybe 10-15 seconds, but is clearly taking longer in our env. Given this, I had a few questions...
- Why does it take this long to start loading the processes?
- Is this time configurable in some way?
- Where in the jbpm-console (gwt) code would one find the logic that deals with loading processes?
In the jbpm user guide, there is a bullet that states the following:
- Currently, the console will load the process definitions the first time the list of processes is requested in the console. At this point, automatic updating from Guvnor when the package is rebuilt is turned off by default, so you will have to either configure this or restart the application server to get the latest versions.
How and where do I configure the console to automatically pick up changes form Guvnor. Currently I have to restart the server, and then wait 3 minutes after to see new processes.
