| <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>.) |
