[JBoss jBPM] - Re: How can i get inform about running tokens/processes.
by exe
My problem is the next:
First: load process instance send signal to token (now the node thread is running ... )
while the node is running i load the process instance from an other jbpm context and try to send an other signal i'll get an exception: "Error signalling token: An exception of type "org.hibernate.StaleObjectStateException" was thrown. " is it ok.
But how can i determine the process has a running unfinished process node (a running action thread in a remoteJbpm context) or not ?
I load the process instance and start a node execution but the node isn't persisted while the node execution is not finished. I need something like this: loadProcess lockProcess->token.signal but i need to list locked (running) intances.
I want to create a "process console" to monitor all process instances and send signal if it is possible
instance 1 (is in node2 wait state) [send signal to token1 t1]
instance 2 (node2)
instance 3 (is in node5 wait state) [send signal child token t1][send signal to child token t2]

[JBoss jBPM] - executing process with timer
by boxwala
I am encountering an error trying to execute a process that has a timer. I am running jbpm 3.2.1 in its app-server form, using the ear file, on jboss AS 4.2.1.GA.
The only change we made in the ear was to modify the hibernate config file since we switched the DBMS to MSSQL 2005. That seems to work okay when we execute processes without timer.
However, in trying to execute a process with timer, there is an issue with the TimerServiceBean not being found. I understand from the documentation that the jbpm-enterprise.jar includes the deployment descriptors for JBoss AS. Did I miss a configuration step in setting up ejb/LocalTimerEntityBean?
