Spring's WebSphereUowTransactionManager & 'application class loader first'

In my application, I am using Spring's (version 2.5) WebSphere specific PlatformTransactionManager class. The full class name is: org.springframework.transaction.jta.WebSphereUowTransactionManager

My spring bean xml file contains the following:

+<!-- Transaction Manager when using JNDI datasource --> +
+ <bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"/> +

+ <!-- enable the configuration of transactional behavior based on annotations -->+
+ <tx:annotation-driven transaction-manager="transactionManager"/>+

When I deploy my application on WebSphere 6.1 all works well. However, when I change the class loading policy from the default '+classes loaded by parent class loader first+' to '+classes loaded by application class loader first+', I run into java.lang.VerifyError: com/ibm/websphere/uow/UOWSynchronizationRegistry.registerInterposedSynchronizat ion(Ljavax/transaction/Synchronization;)

The full exception trace is shown below:

I realized that the spring configuration in my previous post was not displayed correctly. So here it is again.

My spring beans xml file contains the following:

.....

<!-- enable the configuration of transactional behavior based on annotations -->
<tx:annotation-driven transaction-manager="transactionManager"/>

<!-- Transaction Manager when using JNDI datasource -->
<bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"/>

thanks,

tsc

Apologies for the previous posts. In the preview tab, all seems to be ok but when I post the message, I noticed that the characters were replayed with plus symbols.

Once last time, I'll try it again. I have removed the angle brackets just in case.

My spring beans xml file contains the following:

.....

tx:annotation-driven transaction-manager="transactionManager"

bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"

thanks,

Hi,

The fact that you have to change the classloader strategy to application-first is a good hint towards the solution. Most probably you have a jar in your ear / war that is causing the conflict.
I had the same problem and it was caused by jta.jar (1.1 in my case) in the ear file.

Regards,

Hello.
We have the same problem.:confused:

[B]Websphere Application Server 7.0.3 (2-cells cluster)
Spring 2.5.6[/B]

CODE<tx:jta-transaction-manager/>[/CODE]
CODE
<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup"/>[/CODE]

ear application hasn't libraries
all libraries are placed in shared library with isolated classloader

there are many shared libraries except our, but they are isolated too, and they don't used in our application

320 string is

I changed different configurations with classloaders, but there is no solution.
Help please

I need to update the class loading policy to application-first due to the an issue with Commons logging.

Any help is much appreciated!
