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.

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...

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...

When I started my career around 10 years ago, Struts MVC is the norm in the market. However, over the years, I observed the Spring MVC slowly gaining popularity. This is not a surprise to me, given the seamless integration of Spring MVC with Spring container and the flexibility and extensibility that it offers.
From my journey with Spring so far, I usually saw people making some common mistakes...

WildFly tooling is available in JBoss Developer Studio (Eclipse), NetBeans, and IntelliJ. While JBoss Developer Studio and IntelliJ provided in-built support for WildFly, and an extra plugin had to be installed for NetBeans. Not a big deal but NetBeans is more known for a seamless out-of-the-box experience. Starting with today's nightly, WildFly community is a step closer to that now!

Using the Java 8 Date Time Classes with JPA!
With the Java 8 SE release, developers get a splendid new best-in-class Date-Time API. Wouldn't it be nice if you could use it with JPA? Not so fast. JPA and for that matter JDBC know nothing about the new classes, and if you use them in your entities, JPA will map them to BLOBs in your database by default. This happens in DDL or database creation, in...

In an earlier blog entry I listed my picks for DevNexus 2014. This blog entry summarizes my notes from this show.
I corroborate the common wisdom about DevNexus being a very well run show. This was my first time presenting and I found the talk selection on the first day to have the right mix of diversity and depth for the working developer. The second day was much less compelling for me,...

Have you recently checked out your company’s web presence and thought to yourself that it was in dire need of an update? But then maybe you started imagining the pain of pushing new data there, and resigned at the mountain of work ahead.

On January 2nd I received a New Year's gift, my "Welcome to Oracle Cloud" email. I had requested a 30-day free trial back on October 17, when the Oracle Cloud was first announced, and had basically forgotten all about it. If you haven't already, request a trial account for yourself:
The Oracle Cloud integrates very nicely with Eclipse, NetBeans and JDeveloper, where you can develop and...
