{{Update|date=January 2018}}{{Short description|Open-source web service}} '''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).<ref>{{cite web |title=Web Services Interoperability Technology Features |url=http://java.sun.com/webservices/interop/features/index.jsp |archive-url=https://web.archive.org/web/20070128103821/http://java.sun.com/webservices/interop/features/index.jsp |archive-date=2007-01-28 |quote=Web Services Interoperability Technology (WSIT) provides interoperability between Java Web Services and Microsoft's Windows Communication Foundation. }}</ref>
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.<ref>{{cite web |title=Web Services Interoperability Technology Features |url=http://java.sun.com/webservices/interop/features/index.jsp |archive-url=https://web.archive.org/web/20070128103821/http://java.sun.com/webservices/interop/features/index.jsp |archive-date=2007-01-28 |quote=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. }}</ref>
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.{{Citation needed|date=March 2026}}
WSIT implements the WS-I specifications, including: *Metadata **WS-MetadataExchange **WS-Transfer **WS-Policy *Security **WS-Security **WS-SecureConversation **WS-Trust **WS-SecurityPolicy *Messaging **WS-ReliableMessaging **WS-RMPolicy *Transactions **WS-Coordination **WS-AtomicTransaction
