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. Object orientation
(OO) brought in concepts of inheritance, encapsulation, and polymorphism that
could be applied to define relationships between classes. With the prevalence

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.
With the proliferation of an XML-based informa... (more)
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.
In this article we will use a hypothetical scenario in which we configure a
portal search portlet with user-defined categories. We will create
user-defined categories in which the search results will be con... (more)
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.
A Brief Recap
