This happened on jBPM 4.0. Initially I defined a normal timer in my process definition, it worked well but after I changed it to a repeat timer (by adding repeat="30 seconds"), I encountered the following exception:
 
Mar 4, 2010 5:40:35 PM org.jbpm.internal.log.Jdk14Log error
SEVERE: exception while executing 'timer[23|2010-03-04 17:41:05,391|TimeoutEvent]'

Here's my timer definition:
 
<
 
custom expr=+"#{customWaitActivity}"+ name=+"Custom Wait"+ g=+"411,174,126,52"+>
 
<on event=+"TimeoutEvent"+>
 
<!--<timer duedate="30 seconds" />-->
 
<timer duedate=+"30 seconds"+ repeat=+"30 seconds"+ />
 
<event-listener class=+"jbpm.demo.wf.spring.SpringEventListenerDelegate"+>
 
<field name=+"beanName"+>
 
<string value=+"timerExpireHandler"+ />
 
</field>
 
</event-listener>
 
</on>
 
<transition name=+"timeout"+ to=+"Do Something"+ g=+"47,-8"+ >
 
<timer duedate=+"7 business days"+></timer>
 
</transition>
 
</custom>
 
Spring is used to control all the transactions in my project. All the other functions work fine so I think this may be a Spring integration bug of Timer. Here's my Sping Transaction config:
 
<
 
tx:annotation-driven transaction-manager=+"transactionManager"+ />
 
 
 
<bean id=+"transactionManager"+ class=+"org.springframework.orm.hibernate3.HibernateTransactionManager"+>
 
<property name=+"sessionFactory"+ ref=+"sessionFactory"+/>
 
</bean>
 
 
<bean id=+"sessionFactory"+ class=+"org.springframework.orm.hibernate3.LocalSessionFactoryBean"+>
 
<property name=+"dataSource"+ ref=+"demoDatasource"+ />
 
<property name=+"exposeTransactionAwareSessionFactory"+><value>true</value></property>
 
<property name=+"hibernateProperties"+>
 
<props>
 
<prop key=+"hibernate.dialect"+>org.hibernate.dialect.DB2Dialect</prop>
 
<prop key=+"hibernate.format_sql"+>false</prop>
 
<prop key=+"hibernate.show_sql"+>false</prop>
 
<prop key=+"use_sql_comments"+>false</prop>
 
<prop key=+"hibernate.hbm2ddl.auto"+>none</prop>  

</props>
 
</property>
 
<property name=+"mappingLocations"+>
 
<list>
 
<value>classpath:jbpm.execution.hbm.xml</value>
 
<value>classpath:jbpm.repository.hbm.xml</value>
 
<value>classpath:jbpm.task.hbm.xml</value>
 
<value>classpath:jbpm.history.hbm.xml</value>
 
<value>classpath:jbpm.identity.hbm.xml</value>
 
</list>
 
</property>
 
</bean>
 
And jbpm.cfg.xml is properly set up according to the jbpm doc as below.
...
<
 
job-executor threads=+"2"+ idle=+"20000"+ lock=+"2400000"+ auto-start=+"true"+ init=+"immediate"+ />
 
 
<!-- Here we needed to change the transaction interceptor -->
 
<command-service>
 
...
 
<spring-transaction-interceptor />
 
</command-service>
 
 
<!-- Added spring as read-context -->
 
<script-manager default-expression-language=+"juel"+ default-script-language=+"juel"+ 
read-contexts=+"execution, environment, process-engine, spring"+ write-context=+""+>
 
<script-language name=+"juel"+ factory=+"org.jbpm.pvm.internal.script.JuelScriptEngineFactory"+ />
 
</script-manager> 
 

... 
 
 
<transaction-context>
 
...
 
<hibernate-session current=+"true"+ />
 
</transaction-context>
...
 
Could anyone help to take a look? Thank you very much in advance!
