jBPM Web Application in Tomcat with MySQL

[marinav]

Hello Community,

I try to develop a jBPM Web Application with persistence enabled. I want to run this Web Application in a Tomcat 7 server.

For that I created a new dynamic web project in eclipse.

As a maven dependency I added jbpm-bpmn2 and the jbpm-runtime-manager:

<dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-bpmn2</artifactId>
     <version>6.0.0.Final</version>
</dependency>

<dependency>
     <groupId>org.jbpm</groupId>
     <artifactId>jbpm-runtime-manager</artifactId>
     <version>6.0.0.Final</version>
</dependency>

If I now start my server I get this error which is causes by a dependency from the jbpm-runtime-manager:

SCHWERWIEGEND: Exception sending request initialized lifecycle event to listener instance of
class org.jboss.seam.transaction.TransactionServletListener

java.lang.NullPointerException

I has something to do with the seam-transaction.jar.

Did I forget to configure something in my Tomcat 7?

Can maybe someone provide a step by step tutorial about the configurations to run a jbpm web application in a Tomcat 7 server?

I only found tutorials on how to deploy the jBPM-console on a Tomcat.

I hope someone can help me.

Greetings
