To support Oracle Tuxedo application and Web service application integration, the SALT gateway converts SOAP messages into Oracle Tuxedo typed buffers, and Oracle Tuxedo typed buffers into SOAP messages. The message conversion between SOAP messages and Oracle Tuxedo typed buffers is subject to a set of SALT pre-defined basic data type mapping rules.

When exposing Oracle Tuxedo services as Web services, a set of Tuxedo-to-XML data type mapping rules are defined. The message conversion process that conforms to Tuxedo-to-XML data type mapping rules is called “Inbound Message Conversion”.

When importing external Web services as SALT proxy services, a set of XML-to-Tuxedo data type mapping rules are defined. The message conversion process that conforms to XML-to-Tuxedo data type mapping rules is called “Outbound Message Conversion”.
