How to use seam 2.2 with jbpm 4.4?
I want migrate my old application with seam 2.2 and jbpm4.4. Current version is seam 2.0.1 and jbpm3.I am using http://www.lunatech-research.com/archives/2010/03/09/jbpm4-and-seam-working-together approach to migrate my application. While configuring my application with given option, i am getting following exeption.

My jbpm.cfg.xml looks like below:
<jbpm-configuration>
<import resource="jbpm.default.cfg.xml"/>
<import resource="jbpm.tx.hibernate.cfg.xml"/>
<import resource="jbpm.jpdl.cfg.xml"/>
<import resource="jbpm.bpmn.cfg.xml" />
</jbpm-configuration>
I am trying to resolve the issues but still unable to get the root cause of this exception. I guess internally Jbpm.class is getting called of seam's jbpm.jpdl jar is the problem.
Any idea about this error or a way to migrate jbpm4 with seam 2.2 is highly appriciated.
Thanks in advance
