There is no language yet available to replace Java!

There is a perception created in the software development industry that Java is out-dated and Ruby, Python, Scala, etc. are going to take over Java’s position. Some “hyper-enthusiasts” are already left Java platform. Sun’s profit model collapse, Applet, Jini, EJB and JSF heavyweight framework failures added fuel to these campaigns. I still believe no language yet available in the market to replace Java. I don’t have to talk why Java is better because it is proven solution for more than a decade but I would like to talk about how false campaigns are created by “hyper-enthusiasts”. It is easy to fall into these false campaigns because as a developer we want new challenges and something new to learn. Read more of this post

Java – Object XML Mapping

Have you written 1000s of buggie lines of code to parse XML? Generating an XML is easy but when it comes to XML parsing/import it is hard. We have to think about many scenarios and deal with many combinations. I use to prefer XPath API for XML import because I can fetch required values as they way/order I want rather than iterating all nodes in DOM structure. XPath is better than DOM coding but is not the best solution. So I started looking for a solution similar to Hibernate for XML to Object translation. Read more of this post

Single-Sign-On (SSO) in Java Platform using Active Directory

Sorry guys it been long time writing in my blog.

Nowadays single-sign-on became a hot selling feature for all desktop and web-based products. In this article I talk about single-sign-on implementation in Java platform with Active Directory server.
