Hi Naresh,

Considering you're using an XMLPull parser for deserializing objects, 
you might want to look at using JiBX ( in 
combination with your framework. JiBX provides high-performance data 
binding using an XMLPull parser for unmarshalling. This should eliminate 
the need for users to write their own MessageReader and MessageWriter 
implementations in your framework (they'd need a binding definition, but 
that's generally a lot simpler to write and maintain than the actual code).

An ideal solution for message style would couple a data binding 
framework with the SOAP framework so that there are no added conversions 
to and from text. I think that's what's planned for the integration 
between JAX-RPC and JAXB coming down the line. I gather that both SMFW 
and the current Castor binding support actually go through multiple 
conversions to and from text (since AFAIK Axis always parses everything 
going in both directions, before converting back to text), which is 
going to really hurt performance.
