Sanjiva,
The proposal for saving the MessageContext is that the following context
classes implement the java.io.Externalizable interface:
- MessageContext
- OperationContext
- ServiceContext
- ServiceGroupContext
- SessionContext
The ConfigurationContext class does not need to implement the
java.io.Externalizable interface.
Since only a subset of the MessageContext object graph is saved during
serialization, the deserialization of a saved MessageContext only
reconstitutes a subset of the MessageContext object graph. In order to
re-establish the full MessageContext object graph, the restored
MessageContext object needs to be called with an active
ConfigurationContext object that is appropriate for the AxisEngine where
the deserialization is taking place. This is the
MessageContext.activate(ConfigurationContext configCtx) method. The
MessageContext.activate() method uses some metadata that was saved/restored
to re-establish the links to the appropriate Axis* objects. The metadata
typically corresponds to the name associated with the Axis* object.

Re: [AXIS2] Proposal for saving the
message context
Please respond to

I read thru the Wiki page but am a bit unclear on what is proposed. Are
you proposing that:
- All the context classes implement externalizable
- add a method configContext.activate(MessageContext)
Does the externalization involve storing names of the Axis* objects so
that those links can be re-established?
What exactly does activate() do- I didn't see that documented.
Thanks,
Sanjiva.
