VerifyError in Websphere

When deploying my application in Websphere 7.0 I got the following error. It is somehow related to class loading.
I could resolved the comflict by removeing the jta.jar file from the dependencies of my war file.

Caused by: java.lang.VerifyError: com/ibm/websphere/uow/UOWSynchronizationRegistry.registerInterposedSynchronization(Ljavax/tranhttp://www.blogger.com/img/blank.gifsaction/Synchronization;)V

The basic problem is that you should not provide classes that are already provided by Websphere.
The basically remove all "javax" package classes from you war.
