BPEL Unleashed

Fri, 30 Apr 2004 00:00:00 EDT

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 workflow, BPM (business process management), and related business integration projects.

Rise of the Standards-Based Integration Machines

Wed, 29 Oct 2003 00:00:00 EST

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 to address today's business integration and process automation challenges.

BPEL: Make Your Services Flow

Tue, 17 Jun 2003 00:00:00 EDT

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 makers opted to do nothing and wait.

Straight-Through Processing and Orchestration of Web Services

Mon, 21 Oct 2002 00:00:00 EDT

One word can describe the current state within financial organizations as far as straight-through processing (STP) is concerned: confusion.

Web Services in a Pervasive Computing Environment

Mon, 21 Oct 2002 00:00:00 EDT

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.

Building DB2-Based Web Services Using WebSphere, Part 2

Wed, 25 Sep 2002 00:00:00 EDT

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.

Web Services Orchestration

Mon, 23 Sep 2002 00:00:00 EDT

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 the business process is the application.

Web Services and Wireless Messaging

Tue, 27 Aug 2002 00:00:00 EDT

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 organizations, telecommunication operators, and equipment manufacturers responding to trouble reports.

Building DB2-Based Web Services Using WebSphere: Part 1

Wed, 21 Aug 2002 00:00:00 EDT

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 improvements to an existing system - as opposed to applying the technology for the sake of applying the technology.

XML Computation Trees

Wed, 31 Jul 2002 00:00:00 EDT

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 real-world problems: the traveling salesman problem, efficient routing of a package, network flows, and more - all are modeled as graphs and often solved by graph-based algorithms.

Developing Web Services with WebSphere Studio

Wed, 31 Jul 2002 00:00:00 EDT

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 invoking the service. You also saw how the UDDI Explorer is used to publish your service on a public registry so others can find and use it.

Developing Web Services with WebSphere Studio

Thu, 23 May 2002 00:00:00 EDT

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 interoperability possible.

Delivering SOA

Mon, 20 May 2002 00:00:00 EDT

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 architecture.

Welcome to Web Services

Wed, 24 Apr 2002 00:00:00 EDT

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.

Business Flows with BPEL4WS

Sat, 01 Jan 2000 00:00:00 EST

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 educating developers on how to put BPEL to work.
