Business Process with BPEL4WS: Understanding BPEL4WS, Part 1
The recently released Business Process Execution Language for Web Services (BPEL4WS) specification is positioned to become the Web services standard for composition. It allows you to create complex processes by creating and wiring together different activities that can, for example, perform Web services invocations, manipulate data, throw faults, or terminate a process. These activities may be nested within structured activities that define how they may be run, such as in sequence, or in parallel, or depending on certain conditions. This series of articles aims to give readers an understanding of the different components of the language, and teach them how to create their own complete processes. 		Articles 01 Aug 2002  
 
Business Process with BPEL4WS: Learning BPEL4WS, Part 7
In the previous article we examined correlation and fault handling in BPEL4WS. Now, we are going to extend the simple BPEL4WS process that we have been working with in the previous articles by adding the ability to communicate with a pre-existing process instance and to capture faults which may occur during its execution.

Business Process with BPEL4WS: Learning BPEL4WS, Part 6
The previous articles have covered the fundamentals of BPEL4WS, providing you with an understanding of the activities defined and how they can be combined together. In this article, we cover the advanced properties of the language that are essential to the definition and execution of a business process. 		Articles 01 Mar 2003  
 
Business Process with BPEL4WS: Learning BPEL4WS, Part 8
This article illustrates the use of three more BPEL activities: switch, pick, and compensate. In addition to showing how you can branch on conditionals using <switch>, we show how you can use <pick> to branch based on incoming messages or timeouts. A simple explicit compensation example is also presented to show how committed actions may later be undone. 		Articles 16 May 2003  
 
Business Process with BPEL4WS: Learning BPEL4WS, Part 5
The previous example in Part 2 of this series showed how to build a simple BPEL4WS process that invokes a web service. This article takes that example and expands it into the loan approval process that is included in the BPEL4WS specification and the BPWS4J samples. Links connect activities together, and allow the specification of a condition on each that determines whether or not that link should be followed. Conditions in BPEL4WS are XPath expressions, and this article shows how they can incorporate the process's container data. 		Articles 11 Mar 2003  
 
Business Process with BPEL4WS: Learning BPEL4WS, Part 3
The recently released Business Process Execution Language for Web Services (BPEL4WS) specification is positioned to become the Web services standard for composition. This series of articles aims to give readers an understanding of the different components of the language, and teach them how to create their own complete processes. The previous parts of the series gave an overview of the language, and took readers through creating their first simple process. This part will cover each of the activities in more detail. We will also cover how the various BPEL4WS constructs may be represented and manipulated in memory. 		Articles 01 Oct 2002

Discover the business logic of BPEL4WS
This tutorial illustrates the function and benefits of the BPEL4WS specification. The tutorial then explores the application of BPEL4WS in a real-world business process. 		Tutorials 20 Jun 2003  
 
Use RosettaNet-based Web services, Part 2: BPEL4WS and RosettaNet
Sir Isaac Newton once wrote, "If I have seen farther than others, it is because I was standing on the shoulders of giants". We should pay great care to this wisdom and ensure that Web services leverage existing knowledge and expertise to "see farther". The shoulders on which Web services can stand belong to "giants" like RosettaNet, which has already spent the past 5 years creating and implementing automated e-business dialogues between partners. Web services can take these efforts further by applying ubiquitous technologies to the e-business dialogue and bringing the e-business dialogue within affordable reach, enabling widespread use.

Use RosettaNet-based Web services, Part 3: BPEL4WS and RosettaNet
All you ever wanted to know about Web services choreography can be found in a regular dictionary. To do this, you must first realize that Web services are really e-business dialogues -- next, look up the word dialogue in a dictionary. For example, the Merriam-Webster dictionary defines dialogue as a written composition in which two or more characters are represented as conversing. Read the article as I explain how this simple and elegant definition reveals the need for choreography, choreography languages, digital representations, and much more. 		Articles 13 Aug 2003  
 
Use RosettaNet-based Web services, Part 1: BPEL4WS and RosettaNet
While Web services are a gentle evolution of existing technology, they are a revolution in the way business can be represented in software. However, we cannot realize the full potential of Web services, or see their revolutionary nature, unless we start constructing partner-to-partner e-business dialogues that conduct real business transactions. This series of articles demonstrates the creation of a real e-business dialogue by leveraging the industry leading e-business process specifications from RosettaNet, and translating them to Web services using the expressive and flexible BPEL4WS.

Use RosettaNet-based Web services, Part 4: BPEL4WS and RosettaNet
Simply sending SOAP based messages between machines is not really doing Web services -- this is a limited view which obscures the larger picture. To conduct business electronically, you need technology that encourages you to think and act in ways in which business is conducted in the physical world. Web services are an important first step to encourage such thinking and, in this article, Suhayl describes how executable business processes can be created using BPEL4WS. 		Articles 30 Sep 2003  
 
Conversational Support for Web Services: The next stage of Web services abstraction
A new series of Web services protocols -- BPEL4WS, WS-Coordination, and WS-Transaction -- aim to abstract groups of services into easy-to-handle processes. While most developers are just starting to use these technologies, Santhosh Kumaran and Prabir Nandi, two researchers at IBM's T.J. Watson Research Center, are already studying how to take Web services to the next level of abstraction. In this article, you'll learn about Conversation Support for Web Services (CS-WS), an experimental technology from IBM's alphaWorks. You'll learn how conversations can hide the implementation details involved with collecting multiple Web services into real-life business exchanges. Once you finish here, you can download the project's code from alphaWorks and get in on the ground floor of development. 		Articles 01 Sep 2002  
 
Business processes in a Web services world
BPEL4WS allows the definition of both business processes that make use of Web services and business processes that externalize their functionality as Web services. This short paper introduces the basic language elements of BPEL4WS based on a simple example. The concepts underlying the language are briefly explained: establishing bilateral partnerships, correlating messages and processes, defining the order of the activities of a business process, and handling exceptions via long-running transactions. We'll also look at the resulting programming model, and the usage of BPEL4WS in pure B2B scenarios. 		Articles 01 Aug 2002  
 
Build Web sites with BPEL business processes
This tutorial explains how to create a Web site that uses business processes to perform daily business operations. With this example, you build a Web site that takes pizza orders. If the customer has a good credit history, the order is placed, and the time needed for pickup or delivery is calculated and shown on the confirmation page. If the customer has bad credit, an order cannot be placed and the customer is informed. 		Tutorials 01 Jul 2004

From UML to BPEL
This article describes a new tool from part of the Emerging Technologies Toolkit version 1.1 (ETTK) released on alphaWorks which takes processes defined in the Unified Modeling Language (UML) and generates the corresponding BPEL and WSDL files to implement that process. This capability is used to highlight some of the benefits of the Object Management Groups (OMGs) Model Driven Architecture (MDA) initiative: raising the level of abstraction at which development occurs, which, in turn, will deliver greater productivity, better quality, and insulation from underlying changes in technology.
