StackOverflowError with @CreateProcess

[westdwestd.david.west.cusppoint.com]

Hi, I'm trying to use Seam's integration with jbpm to start a workflow

My method is:

@CreateProcess(definition="QaApprove")

public void startWorkflow() {

System.out.println("Starting new workflow");

}

I am getting a stack overflow error as shown below.  Any ideas what could cause this?  I'm using Seam 2.0.1GA and the jbpm jbpm.cfg.xml and hibernate.cfg.xml as in the dvd store sample.

The partial stack trace is:

Is there anything logged that's interesting/suspicious in the server.log prior to that output?

[westdwestd.david.west.cusppoint.com]

Thanks for the reply.

Yes there is something interesting

java.lang.IllegalStateException: Could not start transaction

Debugging the SeamPhaseListener.begin method I see the exception is caused by the  Transaction.instance().begin(); in the render response phase.

I am using postgres as my db, my jbpm.cfg.xml is:

  <jbpm-context>
    <service name="persistence">
       <factory>
          <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
             <field name="isTransactionEnabled"><false/></field>
          </bean>
       </factory>
    </service>
    <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />
    <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory" />
    <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory" />
    <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory" />
    <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory" />
  </jbpm-context>

The top of my hibernate.cfg.xml is:

    <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    <property name="show_sql">false</property>
  <property name="connection.datasource">java:/MyDataSource</property>
  <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
  <property name="transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
  <property name="cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
  <property name="hbm2ddl.auto">create-drop</property>

Any ideas what I might be doing wrong?
Cheers

After an exhaustive search of integrating a hello world type workflow application into my maven build and successively adding parts of my application, I narrowed it down to the spring integration, specifically the line in components.xml

<spring:spring-transaction platform-transaction-manager="#{txManager}">

I found the following article which I'm now going to follow:
