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...

The lambdas are without any doubt one of the most intriguing and attractive features in Java8, but sometimes instead of helping us writting a better and boilerplateless code, they can get us into trouble. And still, they are the better alternative to the anonymous classes for lots of reasons.
The anonymous classes were a nice way to achieve clojures in Java, but it was something natural to...

Runtime type information (RTTI) refers to the correct identification of the type of your objects at run time. When you write code, it is generally desirable to do so in a way that takes advantage of OOP features like encapsulation and inheritance to make your program easily extensible, by for instance, as much as possible manipulating references to base classes and letting polymorphism work for...

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...

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.

It took trains, planes, and automobiles to get there. I had heard Germany ran some great conferences, but JavaLand was promised to be outstanding. Kevin already did an interview with one of the organizers, Markus Eisele, about why JavaLand is different. (https://weblogs.java.net/blog/editor/archive/2014/03/01/java-conferences...) But, I got to see first-hand if they...

The entire point of SSE is to make it easy for the server to push messages to the browser, once the browser has first established a connection to the server. These messages are of the form "field: value" with...
