A Methodology for Service Modeling and Design

Thu, 04 Sep 2008 14:45:00 EDT

When the programming model shifted from the traditional procedural model to that of object-orientation, a major paradigm shift occurred in the world of IT development. The focus was on encapsulating the state and behavior of entities and calling that encapsulation a class. Instances of a class were called objects, which occupied some space in the memory.

From Business Modeling to Web Services Implementation

Part 1 of this article illustrated how to use WBI Modeler 5.1 to model a business process. We used the example of a simple 'Web Order' business process and showed how it can be modeled in a BPEL-compliant mode. The artifacts created in Part 1 were exported into the file system for use as the input to the business process implementation - the topic of this article.

From Business Modeling to Web Implementation

A software development lifecycle begins by trying to understand the system you want to build. One of the de facto ways to understand a system is to model the business processes that collectively constitute its functionality. Each business process is an effort to streamline an enterprise's operations and functions. System architects and designers then use these business process models to come up with a system architecture and implementation that realizes the business processes.

In Part 2 of this two-part series (Part 1 appeared in Vol. 9, issue 4) I shall try to construct an XML Schema, take you through the steps required to convert an XML document into its corresponding Java classes and interfaces, and also show how to generate an XML document (by using the generated Java classes and interfaces) from a Java object tree, in a programmatic fashion.

Using the Search Capabilities of WebSphere Portal v5 Part 2

Tue, 26 Oct 2004 00:00:00 EDT

The first article (Vol. 3, issue 9) in this series on WebSphere Portal Servers (WPS) search capabilities introduced you to some basic capabilities of the native search features of WPS.

Using the Search Capabilities of WebSphere Portal V5 - Part I

Portal applications usually require a search capability. Portal designers usually look into search engine products like Lotus Extended Search or open source implementations like Lucene in order to satisfy the search requirements.

Using JAXB in Enterprise J2EE Applications

Mon, 05 Apr 2004 00:00:00 EDT

It has been well proven over the past few years that the best form of information exchange (in a typical B2B and B2C environment) is through XML. There are various XML-based standards (schema) for both the horizontal and vertical market sectors and there are ongoing efforts to move toward a standardized format in the various industry sectors.

Using JAXB to Develop Enterprise Applications

JAXB (Java Architecture for XML Binding) provides a convenient way to bind an XML Schema to a representation in Java code and makes it easy for developers to incorporate XML data and processing functions into applications based on Java technology without having to know much about XML itself.
