Thanks again Mauricio,
Unfortunately, my work environment is not on the Internet. My internet access is via an email/browser station with very limited functionality. Just importing files from the Internet is a tedious, administrative, and time consuming process. Exporting to the Internet is nearly impossible; I'm afraid I can't provide any code. I am using jBPM version 5.2.0.Final.
I appreciate being able to expose the task server bean as a JNDI resource, but for now, our plan is to have our one app be the one-stop-shop.
I see the LocalTaskService and LocalHumanTaskService classes in the org.jbpm.task.service.local package. Are these the classes I need to start a local task server inside my application? If so, I'll try to Google for examples. Are they independant, or do I need both? Will I still interact via a TaskClient?
Can I do this and still use the custom UserGroupCallback?
I'm sorry I was confusing about the user session info. The JEE realm will not provide me any information beyond HttpServletRequest.getRemoteUser(), and HttpServletRequest.isUserInRole("role_name"). The application/database doesn't know about provisioned users, it only knows the identity string of the current user within the context of a user's session. (It does know about roles/groups, as membership requirements are all over the application, granting access to pages, data, resources, etc.) So, in a session scoped bean, I could implement the UserGroupCallback as long as the only user was the current user. I suspect that won't be possible however, and I'll have to go outside the realm and use the external RESTful interface. I hope that's more understandable.
