Transaction Rollback Exception
Hi,
I'm using container managed transaction of Jboss 3.0 integrated with Tomcat 4.0.3. We are using the Struts framework and Castor.
When i try to modify an existing object, the first time it works fine. the next time it throws the
exception given below. Again the third time it works,4th time exception and so on..
However if we try to modify different objects there is no problem.
In the Deployment descriptor, ejb-jar.xml, <tran-attribute> under <assembly-descriptor> tag is set to "Required". We also tried using "RequiresNew".
