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

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!
