Hi Don,
It would be very nice if we can have generic
persistency layer for axis2 so that other modules can utilize it.
However IMHO if we try to persist a message once
the entire content hierarchy is completed then we may end up with lot of
unnecessary work. What I also feel is if we can save the messages as an when
they are arrive then we only need to save the SOAP content and the transport
specific properties. We used this approach when we develop the initial version
of Sandesha. However when we have the security in place we should let the
security to run first and then we can save the messages after that.In this
case we may need to save some security related properties as
well.
I would also like to give some help as well.
Thanks,
Jaliya

Hi Don,
This is nice. We were planning to develop a
similar functionality for the RM Module. If you develop this module we can
certainly use it.
Some points,
Axis2 has a context hierarchy.
So messages coming in and going out of the system will have some properties
saved in those as well. So you may have to persist some information in other
contexts as well (to make sure that the message could be affectively reused
later). But initially we can start by saving only the message context.
When security module is engaged, it will be the first to eccept
incoming requests and verify them. So make sure that the persistent handlers
of your module are placed after that. If you try to persist before the
security handlers , that may pave the way for a DOS attack.
My
personal view is that this functionality should be a part of the core axis2
distribution. So that not only RM, but other modules also will be able to
use that (e.g. Transaction). So I believe a persistent module should come
with Axis2 (like addressing). (But may not be engaged by
default.)
Thanks,

Happy
new year, folks.
I am planning to develop a module for persistence
the messages and
messaging contexts in and out axis2. I wonder if there
is already such
efforts that have been made, or some good reference
that I can turn
to. Or any suggestions?
Thank
you,
