Application "ATSSample1-new.ear" should be used with WAS z/OS V8,
or with later maintenance levels of WAS z/OS V7 if you experience
errors with a minor code of C9C2C3B.  

(ATSSample1-new.ear has a "TransactionAttribute" of NOT_SUPPORTED,
which overcomes the error caused by the default TX_REQUIRED being
put in play in cases where TX can't be done ... such as outbound
to a batch COBOL program as shown in the EXER3n samples of the Primer.)
