JAX-WS

The Java API for XML Web Services is a Java programming language API for creating web services. It is part of the Java EE platform from Sun Microsystems. Like the other Java EE APIs, JAX-WS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients...

WSIT is distributed under the terms of the CDDL open-source license, and is currently under development as part of project Metro.

WSIT is a series of extensions to the basic SOAP protocol, and so uses JAX-WS

and JAXB. It is not a new protocol such as the binary DCOM.

WSIT implements the WS-I specifications, including:
