Seeking to advance its Web services strategy, IBM
Tuesday launched the IBM WebSphere Software Developer Kit (SDK)
for Web Services, intended to bring Windows and Linux developers into the Java-based Web services fold.
Big Blue also made a point of displaying its continued support of the open source movement by contributing two of its Web services
technologies to the Apache Software Foundation.
Based on core Web services standards like XML
new WebSphere SDK combines technology, tools and core runtime infrastructure which can be deployed on open Web services platforms.
It includes a Java runtime environment based on WebSphere, the IBM Java SDK, an entry level data base, command line development
tools and examples.
IBM said the SDK runs on both Linux and Windows operating systems, adding that future versions will support reference profiles and
scenarios released by the Web Services Interoperability Organization (WS-I).
“By taking advantage of the WebSphere SDK for Web Services, developers can easily generate functional Web services applications for
use across heterogeneous computing environments, including WebSphere,” said Scott Hebner, director of marketing for WebSphere
The newly donated open source code includes the Web Services Invocation Framework (WSIF) and Web Services Inspection Language for
Java (WSIL4J) specifications.
WSIF, currently used by the WebSphere infrastructure software and development tools, is a technology for invoking services described
in WSDL across network protocols like SOAP, JMS and RMI
. IBM said the specification is expandable, allowing it
to support additional transport protocols like instant messaging, and noted that it supports multiple programming models.
WSIL4J will be incorporated in IBM’s upcoming WebSphere Studio version 5. It allows application developers which use Java to access
and process Web Services Inspection Language (WS-Inspection) — jointly developed by IBM and Microsoft — documents on a Web site.
The WebSphere SDK for Web Services is available for download via IBM developerWorks. Both WSIF and WSIL4J are available via the Apache
Software license at the Apache Software Foundation.
