Default Transaction Attribute for EJBs

Question

Guys,
Can you tell me the default transaction attributes if any in Weblogic 7.0 i.e.
the attributes used
if not explicitly specified for a bean method when using in CMT ?
For CMP entity beans,
MDBs,
Other beans (?) :
thanks for your help
regards
Ved

Hello Mr. Woollen,
As always, thank you for your excellent insight into the internals of BEA WebLogic.
I now have a better understanding of what happens "by default" in WLS. I do agree
that changing this now would definitely break existing applications. It's always
difficult to decide when to officially deprecate a "feature" or to leave it in
forever.
Best regards,

I say for better or worse because I would have liked to change it to
always require the user to set a default transaction attribute.
Unfortunately we have many customer's applications who depend on this
behavior, and I believe if we change it we will break all of them.
Regardless, I would not recommend depending on our default tx attribute
and instead always set one for '*'.
In general, entity beans should run as Required or Mandatory. Session
beans are usually required or notsupported. MDBs are required or
notsupported.
