SAAJ is a convenient API that allows applications to exchange SOAP messages containing information encoded in XML, together with arbitrary data held in message attachments. Although it is useful on its own, SAAJ is also the basis for JAX-RPC and for the Java API for XML Messaging (JAXM). This chapter looks at the features that JAXM adds to SAAJ and describes how to configure and use the JAXM reference implementation.

The examples in this chapter can therefore only be used with the JWSDP. JAXM may be integrated into a future release of J2EE, but at the time of this writing, there is no commitment on Sun’s part to do this.
JAXM Overview
SAAJ allows you to construct SOAP messages and send them directly and synchronously to a web service. JAXM builds on SAAJ to provide a higher-level API with the following additional features:
- Messaging profiles
The SOAP messages returned by the SAAJ
MessageFactoryconsist of an empty body and an empty header. However, there are established uses of SOAP that make use of message headers to convey information from the message sender to the receiver, or to intermediate nodes that the message might traverse along its delivery path. JAXM provides the concept of messaging profiles , where a profile represents a specific and standardized way of constructing a SOAP message, such as the ...
