When people ask me what am I doing, my immediate response is IT. Even though, the answer is not very specific, it is the easiest to understand and it still helps to describe what we are doing. In fact, it doesn't matter what programming languages we use, our responsibility is to build the information system, which deliver information to end-user. Therefore, we should value information more than...

When I started my career as a Java developer close to 10 years ago, the industry is going through a revolutionary change. Spring framework, which was released in 2003, was quickly gaining ground and became a serious challenger to the bulky J2EE platform. Having gone through the transition time, I quickly found myself in favour of Spring framework instead of J2EE platform, even the earlier...

Once upon a time, I published one article explaining the principle to build Stateless Session. Coincidentally, we are working on the same task again, but this time, for a multi-tenant application. This time, instead of building the authentication mechanism ourselves, we integrate our solution into Spring Security framework.
This article will explain our approach and implementation.
