As you know, Axis2 assumes that every message it processes is
representable as XML (which is different from CXF where a message can
have different representations, depending on the phase that is
executed). Until now this has always been the case, even for plain
text and unstructured binary data. Are you going to drop that
requirement from the Axis2 architecture

Drop that requirement ( I would say initially Axis2 is designed like that but latter specially in all contract first approaches it has not followed this for performance reasons)  and make an efficient way to work with JSON. Then obviously this won't support WS-Security etc .. which are anyway meaningless for json.

If you look at how ADB works for non security (or non message building case) is similar to this. It stores the xml stream in the Axiom object (this feature has come from axiom differed building) and get that underline stream at the message receiver and directly build the java objects from that. Then at the response also it save the response in OMDatasource and directly serialize to the xml stream at the formatter.

So idea for this is to provide such a direct stream parsing serializing technique which performs well for POJO objects to communicate using json.

thanks,
Amila.
 
or else, what would be the XML
representation of a JSON message received by that message receiver?
