==>> Why its not casting (org.jboss.tm.usertx.client.ServerVMClie
ntUserTransaction cannot be cast to javax.transaction.UserTransaction)
as ServerVMClientUserTransaction is implementing javax.transaction.UserTransaction.

Thank,

Do you have any jta.jar or any other jar which is packaged with your application? If yes, then remove them. I would recommend, you go through the following articles and configure a classloader for your application, so that you dont run into similar issues later:

JBossClassLoadingUseCases

ClassLoadingConfiguration

ClassCastExceptions

Thanks Jaikiran.. it works. now.. getting another error

. let me fight with it otherwise will back to you

once again thanks a lot...
