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:

Re: Spring's WebSphereUowTransactionManager & 'application class loader fir Posted: Jul 29, 2008 03:14:12 PM in response to: tsc's post Reply 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,

Re: Spring's WebSphereUowTransactionManager & 'application class loader first' Posted: Sep 03, 2008 05:32:19 AM in response to: tsc's post Reply 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, Erik-Berndt

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!
