Hi all, Using the formatter to do this is impossible because at the time formatter is getting called the HTTP status code has already been written to the transport.
I don't think we need an axis2 module to do this, it is just setting a property on the axis2 message context and we should not be adding another handler into the axis2 handler chain to do this. I would improve the Fault mediator to be aware about hessian than going for a new module, but there might be a few cases, which will fail by doing that for example if you want to do a protocol transformation from hessian any other. (though this is not possible for the moment because the hessian message builder keeps the binary message as it is and is not going to build the message).
