Metro WSIT

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
  • WS-Security
  • WS-SecureConversation
  • WS-Trust
  • WS-SecurityPolicy
• Messaging
