Web Services Interoperability Technology (WSIT) is an open-source project started by Sun Microsystems to develop the next-generation of Web service technologies. It provides interoperability between Java Web Services and Microsoft's Windows Communication Foundation (WCF).[1]
It consists of Java programming language APIs that enable advanced WS-* features to be used in a way that is compatible with Microsoft's Windows Communication Foundation as used by .NET. The interoperability between different products is accomplished by implementing a number of Web Services specifications, like JAX-WS that provides interoperability between Java Web Services and Microsoft Windows Communication Foundation.[2]
WSIT is currently under development as part of Eclipse 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:
- Metadata
- WS-MetadataExchange
 - WS-Transfer
 - WS-Policy
 
 - Security
 - Messaging
- WS-ReliableMessaging
 - WS-RMPolicy
 
 - Transactions
- WS-Coordination
 - WS-AtomicTransaction

Interoperability is accomplished by implementing a number of WS-*specifications and holding plugfests where Sun and Microsoft engineers work together testing our respective implementations of those specifications. As an extension to JAX-WS, WSIT provides additional interoperability between Java Web Services and Microsoft's Windows Communication Foundation. It focuses on enterprise class features such as security, reliable messaging, and atomic transactions.
