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 contained. Once this portlet is created, installed, configured, and run, we will be able to see the results of the search displayed in one or more categories that we will create. We will be using the same IBM internet URL (www.ibm.com) that we used in part 1 as the site to crawl for content. Setting Up the Collection In this article we will customize the collection that we are going to create. We'll begin with a brief overview of the process involved in setting up the collection and t...

SOA Book Excerpt: A Methodology for Service Modeling and Design - Part 1

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 of the use of OO in the programming world, developers ... (more)

SOA Book Excerpt: Service Oriented Modeling and Architecture - Part 2

Service Oriented Modeling and Architecture (SOMA) is a modeling and design technique developed by IBM that provides prescriptive steps for how to enable target business processes by defining and developing a service-based IT solution. SOMA provides the communication link between the business requirements and the IT solution. It provides guidance on how to use business model and information as inputs to derive and define a service-based IT model. SOMA, as a methodology, addresses the gap between SOA and object orientation. This methodology approach provides modeling, analysis, des... (more)

SOA Book Excerpt: The First-Class Constructs of SOA - Part 3

Normal 0 false false false MicrosoftInternetExplorer4 In SOA, the main emphasis is on the identification of the right services followed by their specification and realization. Although some might argue that object-oriented analysis and design (OOAD) techniques can be used as a good starting point for services, its main emphasis is on microlevel abstractions. Services, on the other hand, are business-aligned entities and therefore are at a much higher level of abstraction than are objects and components. In Part 1 of this book excerpt, we discussed the different layers of an SOA ... (more)

Using JAXB in Enterprise J2EE Applications

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 information exchange, the industry is bound to write lots of Java code to consume XML Schema-based documents. Java Architecture for XML Binding (JAXB) provides a convenient way to bind an XML Schema to... (more)
