SOA Integration SOA Style

The purpose of this whitepaper is to provide a brief introduction to SOA and why organizations need to think about implementing SOA based solutions. It then discusses how SOA can help solve some of the key integration challenges that most companies face. This paper is meant for organizations that are facing application integration challenges and have a need to share business logic and reuse existing applications, and for technical readers who want to provide SOA based solutions to organizations that have such a need.

Unified Authentication & Validation Unified Authentication

Unified Authentication (UA) can protect Internet users from identity theft better than with a scheme that uses regular username and password. A strong authentication mechanism such as UA involves something that the legitimate user already has; this is also called two-factor authentication, the user is required to have confidential information as well as in possession of a physical token. However, how can one prove having such an object on the Internet? Since only information can be transmitted on the Internet, the object can vouch for itself by transmitting information only it possesses. However if the transmitted information is the same each time then it is no better than a regular password. A scheme must be created in which the information transmitted must be different each time; however the authenticator must recognize legitimate transmitted data from illegitimate one.

Code Coverage Code Coverage

The primary deliverable of any software application is the code. This code wires all the application logic that, as we all know has to deliver to an extent that it can be considered reliable enough to automate a business process. The reliability of any system primarily depends on its ability to perform in all possible conditions that the system is designed to work. It is this idea that encourages makers or builders of the system to test it in all possible conditions so as to ensure no or less surprises for the system to handle. This whitepaper highlights the importance of ‘testing the tests’ and profiles some of the Code Coverage products available today.

Source Code Management Source Code Management

A Source Code Management (SCM) repository is perhaps one of the most important data stores a software development organization maintains. One would expect that since developers work with source code every single day, they would understand source control and related concepts extremely well. Our experience, surprisingly, is that developers struggle with source control. This article attempts to explain the basics of SCM and also takes a trip to the console to demonstrate practical usage of two common source code management tools — Rational Clearcase and CVS.

Struts 1.1 vs. 1.2 - Comparison Struts 1.1 vs. 1.2 – Comparison

There have been a considerable amount changes in the Struts framework between versions 1.1 and 1.2 which are significant.
This whitepaper discusses the following:

  • Point out the most significant changes between the two versions
  • Look at changes involved in migrating applications from Struts 1.1 to 1.2

Annotations Annotations

In case you’re unfamiliar with what an annotation is, examining Javadoc is a good place to begin. As most Java developers are aware, Javadoc provides a framework to generate documentation for code by tagging sections of code with certain predefined tags. Each tag is preceded by an @ symbol. This article traces the history of annotations and provides an insight into upcoming implementations of annotations.
