(2) Why do I want to do this:
Most of the participants in our workflow process are computers, not humans. The
process is about ingesting video on demand movies, having them encrypted on one
machine, after this informing a middleware server on another machine, after
this store the encrypted movie on a VOD server etc... This is an automatic
process in which each step can take hours. We do not want to have to restart
the encryption when something fails on the VOD server, we want to be able to
resume the process from the last sucessfull step.
We are using a system like this based on jbpm 2.0 (it is running in the field
now for more than a year, with success). In this system, we had the
participating computers poll jBPM to see if there were states in a process on
which they had to act (just like humans would in a GUI).
What I wanted to achieve now, is replace the polling mechanism by calling the
computer participants from the jbpm process. (create a task for the computer
system, assign it to that system and call the system to perform the task). If
this is unproper, i will stick to the polling mechanism.
Besides, I thing that there is another reason why I should stick to polling. As
far as I can see, only tasks have priorities, and we should be able to give
certain movie ingests priority over other ones. In the polling scenario, we can
have the computer systems scan their task list and pick out the task with
highest prio to start with. From what I understand , the jbpm process itself
does not do much with the task priorities itself, am I correct in this?
(1) There are 2 scenarios:
a) The process is started by a seam componenent (metadataIngesterBean) that is
called from a JSF page and the process calls this component from jbpm. In this
case there is no stack trace, but the @EndTask is not executed. The process
does not continue.
b) The process calls another seam component (metadataIngesterBean2 , not the
one that is called from the JSF page) and then I get a stack trace Here is the
trace of the whole web request):
