from the ejb-2.0 spec, it is a little unclear, but it says that putting a
deafault transaction attribute is ok, and the default will be used for all
methods that are not explicitly defined to have a different transaction
attribute.
so this should work, but if it does not, maybe orion interpreted the spec
differently or has not implemented it correctly....

I already replyed to this message but noticed that it never came through...
so here it is again...
Thanks for the earlier reply.
My reaction:
I understand what you do below, but how must I define all this, such that
- All me methods still have the "trans-attribute" set to Required (as
before).
- Only the new method B has the "trans-attribute" set to RequiredNew ?
So what I am looking for is, some kind of default "trans-attribute" for all
methods, if the trans-attribute" isn't defined for the method in the xml
file.
As in the example below, I need to specify the "trans-attribute" for ALL my
methods separately, which isn't a nice way, as I have a lot of methods, and
it is easy to forget one, especialy when you add a new method.
How do I do this ? (isn't there a way to set the "trans-attribute" property
for methods with a regular expression or something like that ??)
