There is no default transaction attribute for an EJB.?!?
From the EJB 3.1 specification:

"If the transaction attribute type is not specified, it is assumed to be REQUIRED. The absence of a transaction attribute specification on the bean class is equivalent to the specification of TransactionAttribute(REQUIRED) on the bean class"
