Spring AOP + Quartz + WebSphere issue

[tlovasic]

Hi there,
We have a bunch of spring beans that we are running under WebSphere 6.1. We are also using AOP for transaction advice, and things are running well. The issue that we do have is with trying to implement a simple scheduling. We have tried quartz as well as java native timer and both with the same result.
Essentially, we want to use MethodInvokingJobDetailFactoryBean to periodically invoke a method on a bean. As long as that bean does NOT have any transaction advice (and thus does not access a db, but rather just does some println) things work fine. As soon as I wrap the bean into txAdvice so that I may do some db actions as required (or access another bean) I get the following exception:

org.quartz.core.JobRunShell run Job DEFAULT.synchronizerJobDetail threw a JobExecutionException:
org.quartz.JobExecutionException: Invocation of method 'doIt' on target class [class hr.combis.comcon.scheduler.Syncer$$EnhancerByCGLIB $$18bdc41d] failed [See nested exception: java.lang.NullPointerException]

At first I thought this is because of quartz using it's own thread pool, but I have since added taskExecutor which uses WebSphere threadPool, but that did not result in improvements.

Here's our spring config relevant to scheduling:

<bean id="syncer" class="hr.combis.comcon.scheduler.Syncer" parent="baseService">
<property name="actionManager" ref="actionManagerImpl"/>
</bean>

<bean id="synchronizerJobDetail" class="org.springframework.scheduling.quartz.Metho dInvokingJobDetailFactoryBean">
<property name="targetObject" ref="syncer" />
<property name="targetMethod" value="doIt" />
<property name="concurrent" value="false" />
</bean>

<bean id="synchronizerTrigger" class="org.springframework.scheduling.quartz.Simpl eTriggerBean">
<property name="jobDetail" ref="synchronizerJobDetail" />
<!--10 seconds-->
<property name="startDelay" value="60000" />
<!-- repeat every 50 seconds -->
<property name="repeatInterval" value="50000" />
</bean>

<bean class="org.springframework.scheduling.quartz.Sched ulerFactoryBean">
<property name="triggers">
<list>
<ref bean="synchronizerTrigger" />
</list>
</property>
<property name="taskExecutor" ref="taskExecutor"></property>
</bean>

<bean id="taskExecutor" class="org.springframework.scheduling.commonj.Work ManagerTaskExecutor">
<property name="workManagerName" value="wm/default"/>
<property name="resourceRef" value="false"/>
</bean>

And here's our txManager definition:

<bean id="txManager" class="org.springframework.transaction.jta.JtaTran sactionManager">
<property name="autodetectTransactionManager" value="false"/>

</bean>

Any help is appreciated. Thanks!

Can you

1. Post your transaction configuration (you only posted your transactionmanager!).
2. Post the code for your service bean.

[tlovasic]

My apologies. Here's more info:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSes sionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mappingResources">
<list>
...list of tables here...
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Orac leDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.default_schema">some schema</prop>
<prop key="hibernate.jdbc.use_scrollable_resultset">true </prop>
<prop key="hibernate.transaction.factory_class">org.hibe rnate.transaction.JTATransactionFactory</prop>
<prop key="hibernate.transaction.manager_lookup_class">o rg.hibernate.transaction.WebSphereTransactionManag erLookup</prop>
<prop key="jta.UserTransaction">java:comp/UserTransaction</prop>
<prop key="hibernate.cache.provider_class">com.opensymph ony.oscache.hibernate.OSCacheProvider</prop>
<prop key="hibernate.generate_statistics">true</prop>
<prop key="hibernate.cache.use_structured_entries">true</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
</props>
</property>
</bean>

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/dsname"
proxy-interface="javax.sql.DataSource" resource-ref="true"/>

<aop:config>
<aopointcut id="syncerMethodsPointcut" expression="execution(* example.scheduler.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="syncerMethodsPointcut"/>

<bean id="baseService" abstract="true" class="example.AbstractTransactionalService">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
</aop:config>

<bean id="syncer" class="example.Syncer" parent="baseService">
</bean>

The method doIt inside Syncer just does a println. If I remove the pointcut, all is fine, with pointcut, we get the exception listed before.

Thanks again.

At least your transaction manager looks off.. You are mixing hibernate transaction management and the spring transaction management.

Judging by your stacktrace and configuration the problem is your transaction configuration. You don't specify anything on your bean, you disabled automatic lookup, but don't specify a UserTransaction to use...

[tlovasic]

I am not sure what you mean here. I agree that the problem seems to be a transaction configuration. The problem, however, is only present while running a scheduler. Scheduler inevitably does access the thread pool and that makes it different than the other beans in the system.
I do not specify anything on the bean as it is but a sample bean, and it does inherit all session info via baseService, like all our other beans.

Thanks.

[Marten Deinum]

<bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager">
  <property name="autodetectTransactionManager" value="false"/>
</bean>

No autodetecting but also no explicit configuration so what to use?

<property name="hibernateProperties">
  <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.Orac leDialect</prop>
    <prop key="hibernate.show_sql">true</prop>
    <prop key="hibernate.default_schema">some schema</prop>
    <prop key="hibernate.jdbc.use_scrollable_resultset">true </prop>
    <prop key="hibernate.transaction.factory_class">org.hibe rnate.transaction.JTATransactionFactory</prop>
    <prop key="hibernate.transaction.manager_lookup_class">o rg.hibernate.transaction.WebSphereTransactionManagerLookup</prop>
    <prop key="jta.UserTransaction">java:comp/UserTransaction</prop>
    <prop key="hibernate.cache.provider_class">com.opensymph ony.oscache.hibernate.OSCacheProvider</prop>
    <prop key="hibernate.generate_statistics">true</prop>
    <prop key="hibernate.cache.use_structured_entries">true</prop>
    <prop key="hibernate.cache.use_query_cache">true</prop>
  </props>
</property>

Hibernate is accessing the transaction stuff here, not spring...

Your Syncer, doesn't use hibernate, no transaction, no transaction configuration, no transaction... Error...

You seem to be using Websphere, change the JtaTransactionManager to WebSphereTransactionManagerFactoryBean and remove the transactional stuff from hibernate. If you are using spring 2.5 you might want to use the WebsphereUowTransactionManager instead.

[tlovasic]

Many thanks Marten. Your suggestion worked.

To recap, the session now looks like this:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"/>
		<property name="mappingResources">
			<list>
                        ...list of tables here...
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
				<prop key="hibernate.default_schema">some schema</prop>
				<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</prop>
           		<prop key="hibernate.transaction.manager_lookup">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</prop>
				<prop key="hibernate.cache.provider_class">com.opensymphony.oscache.hibernate.OSCacheProvider</prop>
				<prop key="hibernate.generate_statistics">true</prop>
				<prop key="hibernate.cache.use_structured_entries">true</prop>
				<prop key="hibernate.cache.use_query_cache">true</prop>
			</props>
		</property>
	</bean>

And the txManager is now:

<bean id="txManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager">
		<property name="autodetectTransactionManager" value="false"/>
	</bean>

Thanks again.

[Marten Deinum]

Your welcome. Glad it is working now.

Hi,

We are getting similar problem.

We are invoking a spring bean through webservice skeleton and getting the below exception. But when invoking the same spring bean through stateless session EJB the call works fine.

Well I had the same config, everything was working OK with
spring 2.5.2 and hibernate 3.2.6GA (spring commonj websphere 6.1.0.13 UOW tasks) .
Moving to spring 2.5.5 and hibernate 3.3.0GA, it cannot seem to find comp/UserTransaction even though the error still seems to be originating from webspheres j2ee context.

Anybody out there able to confirm this?
