SAAJ 1.1

The SOAP with Attachments API for Java 1.1 (SAAJ) protocol enables applications to send and receive document-oriented XML messages using a pure Java API. SAAJ implements SOAP 1.1 so that developers can focus on building, sending, receiving, and decomposing messages for their applications instead of programming low-level XML communications routines.

See the JAXM/SAAJ Web site for more information.
