Hi,
I have to applications. One of them (A) is using JBPM inside to model some business
process. At some stage the execution is moved to other application (B). The user has to do
something in the second application. After it is done, I need to inform the first
application (A), that it can continue in executing - go to the next node.
The only thing I could come up with is this:
the first application (A) will use async=true and JmsMessageServiceFactory. when the async
node is entered, it will send email to the user with link to the second application (B).
He will log in, make work in the second application. After he finishes, JMS message will
be sent to queue, that A application will understand and will continue.
However I was not able to find out, which kind of message it should be and how can A
application restart its working. I've read many sources but haven't find
solution.
If somebody can help and show me the client code and how to do response in A
application...
Thanks a lot
Uwe

why not using state activity instead? I think it is perfect to put application A process
in wait after signaling application B. Once application B is done with its work it will
signal back application A to continue with the flow.
About JMS, jBPM 4.4 has support for JMS integration but only outbound traffic, so you
shall use another technique to trigger process to continue... For more information about
JMS activity take a look at dev guide

Actually we are using jbpm 3 with seam 2.2. :(
The application A is bundled with jBPM, but B is without.
Meanwhile I was able to prepare code that maybe could send JMS message from B to A. If
the message itself contains jobId, the JobListenerBean will execute the job. (discovered
from source code)
But I have 2 problems.
1. How to get know the jobId itself? (The app B doesn't know that. Maybe it could be
somehow handled with app A when creating the job, but that's also something I
don't know how..)
2. The A app cannot be deployed, because JmsMessageServiceFactory is not found. I found
it's it jbpm-enterprise.jar package and I tried to add it to the .ear as module, that
was successfull, but again when deploying, it fails with exception that it cannot find
java:/JbpmDS datasource ("type-mapping is not initialized: java:/JbpmDS was not
deployed or type-mapping was not configured.") That is correct as I didn't
specify any. I would like to specify it, but I don't know, where it should point to.
Should it be the same db as used in the app or another?
Thanks for suggestions
Uwe

Uwe, your design is unnecessarily complex because you are trying to incorporate jBPM
internals which are not meant for external usage. I would model the process as follows.
<process-definition name="callback">
<start-state>
<transition to="send-mail" />
</start-state>
<mail-node name="send-mail">
<transition to="wait-for-callback" />
</mail-node>
<state name="wait-for-callback" />
</process-definition>
Once the user performs the work indicated in the email, application B should send a plain
message to a queue with a long property set to the token ID. In addition you should code a
simple MDB that reads this message, loads the referenced token and signals it. That's
all. You should not try to involve JmsMessageServiceFactory.
