Back to Basics – Fresh new start
I remember almost 5-6 years back when I started learning many programming languages, .Net (1.1) was one of my favourite framework and C# was the language of choice. The event based programming model, readymade suite of components with ASP.Net was definitely an interesting way to develop web applications.

I am not addicted to Coffee
Almost 7 years back when, I joined first organisation, inspite the fact of knowing languages like Visual Basic 6.0, ASP, Java 1.2, PHP 4, C, Shell Script, Oracle PL/SQL, MySQL [and little bit .Net] etc., I started working on HTML and JavaScript.

Codemodel – Java Code generation library
I was looking out for a utility/library which can be used to generate Java Source code. Initially I thought of using source code templates and generate Java Files from it. But fortunately I came across an interesting library CodeModel. This library is used by most of the popular code generators including JAXB. The library provides [...]

IBM Websphere – Worst NiGhTmArE (NoClassDefFoundError – com.sun.org.apache.xerces.internal.dom.DocumentImpl)
Last week, I was trying to deploy CXF 2.X webservice application on Websphere 6.1.0.X. Everything worked well and no error at the time of deployment. But while invoking webservices, we were getting an error java.lang.NoClassDefFoundError: com.sun.org.apache.xerces.internal.dom.DocumentImpl After googling, we found that this class is integral to JDK 1.5 and ships along with it. We were bit [...]

Do we have right community?
I recently interviewed one technical guy who is supposed to be a good resource in his project. Since the guy has spent most of the time working on Messaging, I thought of asking some questions on Messaging and threats that exist for messaging (No I haven’t worked much on messaging, but as a habit I [...]
Apache Common Chain
There is always a need to develop component based architecture with a flexibility to have loosely coupled units. While it is perfectly valid that a component may be dependent upon an output produced by another component, it shouldn’t be aware of how and from where the data is retrieved. The task of fetching data and [...]
Apache CXF – Code First – Schema validation demystified
In my previous article, I talked about how you can use schemaLocation property to override default CXF behaviour for Code First approach. But the approach had one major problem – Defining entire schema structure in one XSD file. After spending few hours finding an option to get rid of this problem, I could finally found [...]

The introductory video gives a good overview of framework and features listed in documentation has really created some curiosity. I am planning to explore it. Has anyone used this framework, if yes [...]
