SOMERS, NY - 27 Jun 2002: -- IBM today announced the IBM WebSphere* Software Developer Kit (SDK) for Web Services to promote the adoption of Java(TM)-based Web services among Windows and Linux developers. In addition, IBM has contributed two Web services technologies to the Apache Software Foundation to advance the development and adoption of Web services in the open source community.

The new WebSphere Software Developer Kit (SDK) for Web Services will make it easier for developers to take advantage of the latest in Web services technology to design and create Web services for integrating companies, customers, suppliers and employees over the Internet in heterogeneous environments.

This "starter kit" complements IBM's flagship WebSphere software development portfolio. Applications designed and built using the WebSphere SDK for Web Services can be used and deployed easily in IBM's WebSphere application server and Studio development tools.

IBM's WebSphere SDK for Web Services combines basic software components - technology, tools and core runtime infrastructure - needed for developers to design, build and test Java-based Web services. These can be deployed on open Web services platforms, such as IBM's WebSphere infrastructure software. The WebSphere SDK for Web Services is available at no cost via developerWorks, IBM's online resource for developers, and the WebSphere Developer Domain.

Based on open standards such as XML, SOAP, UDDI and WSDL, the WebSphere SDK for Web Services includes:

The WebSphere SDK for Web Services runs on both Linux and Windows operating systems. Future versions plan to incorporate new Web services features and functions in support of the Web Services Interoperability Organization's (WS-I) upcoming reference profiles and scenarios. The WS-I is an open, industry organization chartered to promote Web services interoperability across platforms, operating systems and programming languages.

WebSphere Technologies Open Sourced
In addition, IBM has donated the source code for two additional Web services technologies to the Apache community of open-source software projects.

The two IBM WebSphere technologies -- called the Web Services Invocation Framework (WSIF) and Web Services Inspection Language for Java (WSIL4J) -- complement existing Web services technologies in Apache and will further promote the development of Web services in the open source community.

IBM's WebSphere infrastructure software and development tools currently use WSIF. IBM will use the WSIL4J code in the recently announced WebSphere Studio Version 5.

Web Services Invocation Framework - WSIF is a technology for invoking services described in Web Services Description Language (WSDL) across a variety of network protocols, such as Simple Object Access Protocol (SOAP), JMS and RMI. It provides the ability for Web services to be deployed in a flexible way. WSDL describes a Web service and its capabilities.

WSIF is expandable and can easily support additional transport protocols, such as instant messaging. It also supports multiple programming models and enables developers to interact with Web services applications, regardless of how the Web service is implemented and accessed.

Web Services Inspection Language for Java - Application developers who use the Java programming language can use WSIL4J to access and process Web Services Inspection Language (WS-Inspection) documents on a Web site. The WS-Inspection specification, co-developed by IBM and Microsoft and published in late 2001, defines how an application can inspect a Web site for available Web services.

WS-Inspection complements the Universal Description, Discovery and Integration (UDDI) global directory technology by facilitating the direct discovery of available services on Web sites that are not listed in the UDDI registries.

WSIF and WSIL4J has been open sourced via the Apache Software License. The technologies can be downloaded from the Apache site at: More information about WSIF and WSIL4J can be found on the IBM developerWorks Web Services zone at and the WebSphere Developer Domain at

IBM's past open source contributions to Apache include Simple Object Access Protocol for Java (SOAP4J) in June 2000 and XML4J in November 1999. IBM also offers the source code for the Universal Description, Discovery and Integration for Java (UDDI4J) and Web Services Description Language for Java (WSDL4J) specifications on the developerWorks Open Source Zone.

"IBM is committed to promoting and easily facilitating the adoption among developers of the open technologies necessary to realize the value of Web services development," said Scott Hebner, Director of Marketing, IBM WebSphere Software. "By taking advantage of the WebSphere SDK for Web Services, developers can easily generate functional Web services applications for use across heterogenous computing environments, including WebSphere. In addition, contributing WSIF and WSIL4J to Apache further illustrates IBM's commitment to truly open and extensible Web services technologies and the open source community in general."
