I'm trying to configure this environment, I'm using jbpm4.4, seam 2.2, I followed this instructions: http://www.lunatech-research.com/archives/2010/03/09/jbpm4-and-seam-worki... http://www.lunatech-research.com/archives/2010/03/09/jbpm4-and-seam-worki... but there is something missed. I'm getting this exception: java.lang.NullPointerException 13:18:20,818 ERROR [STDERR]     at org.jbpm.pvm.internal.processengine.ProcessEngineImpl.checkDb(ProcessEngineImpl.java:152) 13:18:20,818 ERROR [STDERR]     at org.jbpm.pvm.internal.processengine.ProcessEngineImpl.<init>(ProcessEngineImpl.java:105) 13:18:20,818 ERROR [STDERR]     at org.jbpm.pvm.internal.cfg.ConfigurationImpl.instantiateProcessEngine(ConfigurationImpl.java:100) 13:18:20,818 ERROR [STDERR]     at org.jbpm.pvm.internal.cfg.ConfigurationImpl.buildProcessEngine(ConfigurationImpl.java:92) 13:18:20,818 ERROR [STDERR]     at org.jbpm.api.Configuration.getProcessEngine(Configuration.java:126) 13:18:20,818 ERROR [STDERR]     at xx.xx.xx.jbpm.Jbpm.init(Jbpm.java:37) It is related with jbpm.cfg.xml file: <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> What is wrong???
