[transaction] transactional file access
Hello,
I saw that commons transaction provides an implementation of transactional file
access and an abstract implementation of javax.transaction.xa.XAResource. Now I
wonder why these two are not combined and the transactional file access
implementation does not exist as a XAResource. Is it so difficult, such a huge
step forward? Or was there just nobody missing it?
I might have some need for it ...
Thanks,
Jörg

Sounds correct to me.

Let me know when you have anything or want more discussion about the topic!

I guess it is less a question of correct working than of integration. We have
the need to run database updates, to execute Corba services and to modify the
filesystem in transactions. From what I get (it's my first real contact with
transactions not limited to databases) most of the TransactionManagers are based
on Sun's JTA which is again based on the XA specification. So wrapping an
existent transactional file access within a XAResource would be the simplest way
to go, wouldn't it?

Not yet :)

Hi Jörg,
I do not think it should be too difficult, but what would be the real
benefit? The XA resource would store files locally only and a real 2
phase commit does not work with the transactional file system.
Anyway, if you have a decent running implementation of that and want
to donate it to the commons transaction project, I'd be my pleasure to
add it.
