---------------------------------------------
Hi Charith,
I have checked in the basic message store API and the in-memory message store
impl. I also checked in the JMX MBean and the sample you have provided. We can
go ahead with those stuff for the 2.0 release. We'll keep the JMS message store
for a later release. It would be great if you can provide some basic test cases
for the configuration stuff.
Thanks,
Hiranya

> Currently when Synapse attempts to send a message and if it fails, following
> actions can be configured to deal with the error:
> * Execute a fault sequence and handle the failed request gracefully
> * Fail-over to a different endpoint
> In addition to these, Synapse ESB should support the "dead letter channel"
> enterprise integration pattern to deal with various errors that might occur
> during mediation or while sending. With the dead letter channel, the failed
> message will be put into a message store in the ESB. Later the ESB can retry
> to send the messages in the message store.
> We should be able to have multiple implementations of the actual message
> store and should be able to configure which store to use for a particular
> scenario. Users should be able to implement their own message stores and plug
> into the ESB easily. To start with we can have a simple in-memory message
> store and a persisting store based on JDBC or JMS.
