Local EJB, Hibernate and JTA?

[melsom]

Hi

I have the following configuration of my Hibernate sessionfactory and the JTA transactionmanager on Websphere.

!--Transaction manager-->
<bean id="rep.pen.jtaTransactionManager" class="org.springframework.transaction.jta.WebSphe reTransactionManagerFactoryBean"/>

<!-- Hibernate SessionFactory Definition -->
<bean id="rep.pen.sessionFactory"
class="org.springframework.orm.hibernate3.annotati on.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="rep.pen.dataSource" />
</property>
<property name="jtaTransactionManager" ref="rep.pen.jtaTransactionManager"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.DB2400Dialect
</prop>
<prop key="hibernate.query.jpaql_strict_compliance">
true
</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.connection.pool_size">50</prop>
<!--
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQ LDialect</prop>
-->
</props>
</property>
<property name="entityInterceptor">
<ref bean="persistentDomainObjectHibernateInterceptor" />
</property>
<property name="eventListeners">
<map>
<!-- This event listener should be removed as soone as lazy loading is handled properly -->
<!-- <entry key="post-load"><bean class="no.nav.repository.pensjon.util.EagerLazyLoa ding"/></entry>-->

</map>
</property>
<property name="annotatedClasses" ref="rep.pen.annotatedDomainClasses"/>
</bean>

I want to use local SLSB to wrap a POJO that dows my logic (using hibernate). The session is opened using OpenSessionInView.

When doing this I get the following exception in my log:

Any ideas? Anye help would be appreciated.

Please use [ code][/code ] tags (without the spaces) when posting code, that way your code remains readable.

Which version of Websphere are you on?

[melsom]

Hi

Thanks for your tip ;-)

I am using Websphere 6.1 and Spring 2.0.1. I have changed to using the JtaTransactionManager and not the Websphere specific one. Now getting this error

Caused by: java.lang.IllegalStateException: Either 'userTransaction' or 'userTransactionName' or 'transactionManager' or 'transactionManagerName' must be specified

when I change to using ...jta.JtaTransactionManager.

[Marten Deinum]

If you use websphere 6.0 or higher it is recommended to use the WebSphereUowTransactionManager.

[melsom]

Ok, but what if I cannot upgrade spring for a while and need to test my transactions.

[Marten Deinum]

I assumed you where on Spring 2.5, which obviously isn't the case.

The WebSphereTransactionManagerFactoryBean you used should work. You might try the configuration where the use the combination of the JtaTransactionManager and the WebSphere FactoryBean as explained in the javadoc.

Next to that you might have a classloading issue, make sure that there is only 1 version of the jta.jar (or the classes in there) on your classpath.

I now have this config and error message

<bean id="rep.pen.jtaTransactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">

This can typically be a classloading issue?

[Marten Deinum]

I expect it to be a classloading issue, a small search points to this thread which removed the jta.jar from the library (jta.jar is also/already provided by WebSphere and shouldn't be included in your app). Also playing around with the classloading order (PARENT_FIRST or LAST might help).

However I expect it to be a classloading issue especially the 'incompatible with' message points in that direction.

[melsom]

It was classloading issues. jta.jar was in two different versions (one in tha application) and one in the server. Removed it from tha application, and it seems to be working now...

Thanks!
