Stuck with jbpm3, seam 2.2 - ungooglable exception
Hi,
I'm new to seam, and I have a problem with jBPM. Maybe you can skip the rest and point me to some documentation on how to use jbpm3 with seam. But I've really been googling and I read the included docs.
What I get is an exception from jBPM when deploying any process, even empty, like
<?xml version="1.0" encoding="UTF-8"?> <process-definition xmlns="urn:jbpm.org:jpdl-3.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:jbpm.org:jpdl-3.2 http://jbpm.org/xsd/jpdl-3.2.xsd" name="emptyprocess"> </process-definition>
What I did:
installed jboss-5.1.0.GA;
installed jbpm-installer-3.2.6.SP1.jar with MySQL
;configured mysql and all needed -ds.xml files;
Got Jboss tools and all
In the project, I've put hibernate.cfg.xml and jbpm.cfg.xml, which I found somewhere. Diffing to dvdstore versions, I have a different datasource name and the sql dialect and create-drop is changed to update.
Basically, I have no idea how Seam works with jBPM - will Seam adnotations in beans deployed with jpbm-console along with the process work?
Anyway, when deploying the EAR of a small app, I get an exception. I tried cleaning the DB and various other things. jbpm-console works, if user data is imported. The jbpm section:
<bpm:jbpm> <bpm:process-definitions><value>board/processes/test1/emptyprocess/processdefinition.xml</value></bpm:process-definitions> </bpm:jbpm>
The exception:

I tried various things, but I'm out of hints where to look.
Thanks,
