Pervasive computing is taking the world by storm. Industry analysts are predicting that mobile is the 'next paradigm shift,' and vendors (including IBM) are investing heavily in producing the best toolset for building applications for pervasive computing.
In my previous article (WSDJ, Vol. 1, issue 7), I gave you a glimpse of the Web Services Object Runtime Framework (WORF), a set of tools for implementing Web services with DB2 and WebSphere. WORF is deployed on WebSphere Application Server (WAS) and uses Apache SOAP 2.2.
In the past decade 'workflow' has become one of the most overloaded terms in the software industry. Almost every application is tagged as 'based on workflow.' While this doesn't always mean a lot, there is good reason for it; it involves recognition among software architects that t...
Field workforce management is an application segment responsible for scheduling resources working in the field, assigning work orders, dispatching work, and letting workers report from a mobile terminal. Among those using such systems are utilities, construction crews, maintenance orga...

So you've heard all about how great Web services are and how they are revolutionizing the way distributed systems are being developed. You've read all about how this new set of standards is changing the Enterprise Application Integration (EAI) space and how it's finally making inter...
Welcome to the newest addition to WebSphere Developer's Journal. This column is devoted to the subject of Web services within the WebSphere family of products.
IBM is one of the most dominant players in the push for Web services. It's therefore not surprising that much of the Web services work done by the company has been incorporated into their flagship product - the WebSphere Application Server. As of version 4, support for Web services is ...
