Doron Sherman is the CTO of Collaxa, Inc., a Web Service Orchestration Server vendor and a BEA Partner located in Redwood Shores, California. He has been involved with Java since its early days and pioneered application server technology while being a founder and chief scientist at NetDynamics.
BPEL (Business Process Execution Language) makes business processes and composite Web services first-class citizens of the Java and .NET platforms, while preventing vendor lock-in. The result is a drastic reduction in the complexity, delivery time, and cost associated with implementing...
It occurs to me that my choice of title for this guest editorial may be at least partially influenced by the recall-induced elections in California (can you see the Arnie connection?). But this column is not about politics; it's about a new, industry-standard ecosystem built around XML...
Until now, the options available for implementing business flows in a typical enterprise-computing environment were daunting. IT project managers had to choose between complex high-end EAI/BPM solutions and high-risk application development projects. More often than not, IT decision ma...
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...
I've been involved with Web services for more than a year now. After the initial fascination and learning curve that are part of any new technology comes the part where you roll up your sleeves and start applying it for the sake of solving real problems or making architectural impr...
Every computer science undergraduate program in the world has two important foundation courses: data structures and algorithms. Open any book on these subjects and you'll see immediately that almost a third of it is devoted to graphs. Graphs are used to model a very large number of rea...
In my last article (WSDJ, Vol. 1, issue 4) I showed you how to use WebSphere Studio Application Developer (WSAD) to develop and publish a Web service. You saw how to use the Web services wizard to wrap an existing Java method as a Web service and expose the metadata required for invoki...
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...
With the rapid adoption of Web services standards and increasing support for asynchronous and XML-based messaging in the J2EE specification (JMS, MDB, JAXM, JAXRPC), it's time to address the challenges involved in building business applications based on a service-oriented architect...
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.
BPEL4WS is now moving rapidly into becoming the de facto standard for Web service orchestration with most platform vendors following in IBM and Microsoft footsteps after the submission of the specification to OASIS. This increased momentum and visibility will drive a great need for edu...
