[jboss-user] [JBoss jBPM] - Running Seam and JPBM in a separate schema

[Bas Rutten]

Hi,

I'm using Seam 2.0.1.CR1 together with JBPM 3.2.2 and JTA. I want to keep the JBPM files in a separate database schema. 

I've set up two persistence units (one for my application tables and one for JBPM) and this all seems to work fine; the JBoss 4.2.1 application server deploys my EAR file without any problems, and my jbpm process definition is correctly deployed to the database. 

 However, when I try to invoke any function that uses JBPM, I get the following error:

Caused by: org.jboss.util.NestedSQLException: Could not enlist in transaction on entering meta-aware

I'm not sure what goes wrong here but it seems I cannot open a transaction or connection to the database that contains the jbpm files. 

I tried to change the "isTransactionEnabled" attribute in the jbpm.cfg.xml file from "false" to "true" but if I do this Seam complains that I should change it back to "false". 

My question: is it at all possible to use Seam + JBPM + JTA and have the JBPM data stored in a separate database schema? If so, how do I need to configure the configuration files like "jbpm.cfg.xml"???
