Did you configure jbpm 4.4 with seam 2.2??, I have problems with the jbpm.cfg.xml config, it thrown an exception, I followed the same article, but I don't know what's wrong....
my jbpm.cfg.xml:
<jbpm-configuration>
<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>
</jbpm-configuration>
this is the exception
13:18:20,818 ERROR [STDERR] java.lang.NullPointerException
