[AXIS2] Saving the message context
Hi,
I am investigating how to save and restore the message context in AXIS2.
This is functionality that would be used, for example, by
WS-ReliableMessaging to recover from a server/engine restart. This would
also involve having a plugpoint for handlers to be able to save and restore
their message context-related data (for example, the security handler might
need to save a certificate or to re-establish a credential/token).
I have noticed that many of the classes involved with the MessageContext
reference java.io.Serializable although few actually implement it. Has
there been any thoughts or work regarding this?
Thanks,
Ann

I can remember Chamikara from WS-RM team did some thing like this. You
can either wait for him to see this or ask in Sandesha-dev list.

We avoid this in Sandesha by storing the message instead of the message
context. Please ask on sandesha-dev and I'm sure someone will explain
how its done.

Yes, don't do it :). We should remove the Serializable markers- those
were left over from an attempt a while back. Saving the entire context
hierarchy and bringing it back via serialization just doesn't work.
