Moose is a framework for getting XML into and out of Java software. It integrates easily with Spring, Spring Web Services, or plain Java applications. It will generate an XML schema which describes your mapping configuration. Spring Web Services can wrap Moose's schema generator, creating a nice stack for simple, rapid development of SOAP Web services in Java.
XmlPlus xsd2cpp is a tool that compiles an XML schema into C++ data bindings. When invoked on an input XSD file, it generates the C++ sources (implementation/headers) for the supplied XML schema, a main.cpp template to demonstrate how generated sources can be consumed, and the automake/autoconf files for building the generated source.
