Building Web Services Using Windows Workflow Foundation

Tue, 06 Jun 2006 11:00:00 EDT

Microsoft Windows Workflow Foundation (WF) serves as a framework for integrating a workflow engine into applications. The same framework can be used to coordinate information flow between multiple Web Services. This allows developers to create long-running Business Process using WF workflows and expose them as Web Services to be consumed by external applications. Doing this provides a complete environment that provides tracking, state management, transaction support, concurrency constructs, and rules support for expressing business constraints. The goal of this session is to show developers how you can use the WF to support SOA-enabled services.

What Is Windows Workflow Foundation?

Mon, 23 Jan 2006 08:45:00 EST

Most businesses require processes to function properly. There are different types of processes. Some processes are human-intensive, others machine-intensive, and the last type is a combination of the first two. Some examples of business processes are payroll, new product introductions, new employee hiring, etc. In most cases, these business processes require intervention from multiple entities and thus, are normally long running.

The Problem with XML-Based Storage

Fri, 22 Feb 2002 00:00:00 EST

As Java and XML continue as the de facto standard for developing enterprise applications, issues arise in using these technologies. For example, the need to store XML data, and the criteria for selecting the appropriate repository. Here's a real-world example of how applying XML to the wrong problem can lead to the wrong solution.

The Role of XML in Workflow-Based Applications

Sun, 03 Jun 2001 00:00:00 EDT

Process- or workflow-based applications are making a comeback. They ease the concept of plug-and-play functionality by separating application logic into discrete individual components that can be replaced at deployment time by existing infrastructure logic. This type of approach allows us to develop software to the 80/20 rule. Using this rule, enough functionality can be provided out of the box to solve a specific problem (80%) without customization. Over time, the software can be enhanced and customized to leverage enterprise application data (20%) without modifying the overall business solution.

Can XML and XSL Coexist in the J2EE Blueprint

Mon, 08 Jan 2001 00:00:00 EST

When developers talk about the J2EE Blueprint and how it's going to solve world hunger, I get a little worried. Don't get me wrong. The framework has its merits and I agree with the principles outlined by the MVC pattern. What worries me is its total focus on Java. This month's column discusses the J2EE Blueprint and the XML and XSLT technologies that make the framework a true B2B solution.

When Should Java And XML Be Used For Messaging?

Mon, 16 Oct 2000 00:00:00 EDT

When does it make sense to use JMS (Java Message Service) and XML to support a heterogeneous messaging environment? Most buzzword-compliant people talk about JMS and XML when thinking about developing a messaging solution for their organization.

XML 'Programming'

Mon, 16 Oct 2000 00:00:00 EDT

This month I'd like to continue on the theme of technology reincarnation that Israel Hilerio introduced in October's editorial. Technologies undergo a life cycle. Some of the facets of this life cycle are repeated among the different technologies. XML is no exception. However, the challenge is accepting an entity, be it a technology or a person, for what it is. Everything has a natural place and order in this universe, including specific technologies. The origin of an entity plays an important role in determining its role in the computing universe.

Interview...with Paul Mitchell - President of CodeMarket

Sun, 01 Oct 2000 00:00:00 EDT

CodeMarket is a global software development network where software developers and development managers can find and purchase freelance development work and ready-to-run Java components. It recently formed a partnership with ParaSoft, a provider of software error-prevention and error-detection solutions. ParaSoft's Jtest, a Java unit testing tool, will be the standard tool by which all components outsourced or purchased through CodeMarket will be tested.

Reincarnation of Technologies

This month I'm sitting in Ajit Sagar's seat while he takes care of family matters associated with the recent death of his father.

Java, XML and the Command Patter

Fri, 18 Aug 2000 00:00:00 EDT

This month's column shows the advantages of using Java and XML to implement the Command Pattern. It also provides a brief illustration of how this pattern can be used to implement transaction integrity via compensating actions.

XML-RPCs and Java

Thu, 15 Jun 2000 00:00:00 EDT

Computer paradigms are cyclical - they come, go...and come back around. Remote procedure calls (RPCs) are one such paradigm. This month's column focuses on the promise of ubiquitous communications in the Internet using XML-RPCs and RMI.

Java and XML: The Promised Land

Mon, 28 Feb 2000 00:00:00 EST

Welcome to Java and XML - the promised land. In the context of these two technologies the promised land presents a series of solutions in which the marriage between Java and XML has provided an optimal answer for solving distributed multiplatform problems. But do XML and Java actually pave the road to data interchange nirvana? Let's embark on a journey to analyze and evaluate the hype and the reality of the solutions offered by the combination of these technologies. Throughout this journey we'll explore the architectural merits associated with deploying these solutions.

XML & Java: The Why and the How

Wed, 01 Sep 1999 00:00:00 EDT

Today the technical media talks a great deal about the Java platform and its importance in creating a ubiquitous Internet execution environment. While most of us have bought into this concept, other technologies that are emerging rapidly promise to smooth out the road to the computing promised land. XML is one of these technologies that needs to be taken seriously. There are many aspects of XML: Document Type Definitions (DTD), Style Sheets (XSL), Viewers, parsers, HTML 4.0 and data. Out of these, perhaps the most promising aspect of XML is its ability to represent data. Its ability to describe its document content via its markup mechanism allows it to behave like a universal data format for any number of applications.

URL ClassLoader

Thu, 01 Jan 1998 00:00:00 EST

One of the primary reasons for the success of Java has been its robust dynamic class loading mechanism. The Java Virtual Machine ClassLoader is a mechanism that Java uses to load classes at runtime. Techniques to take advantage of Java's dynamic nature and the interactive nature of the Web usually create a spark of interest in the Java community.
