Can anyone point me a simple way to share data between handlers in different flows?

[José Ricardo da Silva]

Hi, I've searched on the list archive and found only quite old
conversations about sharing data between handlers.

I was wondering if someone could point me a very simple way to store
data (objects) when a message arrives (InFlow) and possibly read it
when a message is sent (OutFlow) or when an AxisFault arrives.

Thanks in advance,

José Ricardo.
