[jboss-user] [JBoss Seam] - Re: seam annotations in components called from a jbpm proces

(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
