<h1>Supporting new/custom message types with MessageBuilder/Formatter</h1>
<p>Axis2 provides extended support for new or custom message types. This is done with
using a extension point in the Axis2 architecture, called message builders and formatters.
In Axis2 a builder is responsible of building the MessageContext by looking at the raw message
transmitted and the formatter is responsible of the inverse of that, which is to serialize a
MessageContext to the wire transfer format. Let's create a
custom MessageBuilder/Formatter to add the support for a new message type.</p>
<p>Send your feedback or questions to: <a class="externalLink" href="mailto:java-dev@axis.apache.org?subject=[Axis2]">java-dev@axis.apache.org</a>.
( Subscription details are available on the <a href="../mail-lists.html">Axis2 site</a>.)
Kindly prefix subject with [Axis2].</p>
