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...

Until now, early builds of JBoss Tools were released at a regular cadence leading up to the release of a particular version. Anybody could download, integrate the plugins in Eclipse, test, and provide feedback....

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! This means...

Open Source

This year, more more apache based company, I mean that a company that repackage, retest or make a bundle of Apache product, selling product in Indonesia. And as we know, the ecosystem, like tech guy, expert in our region Asia Pasific, i never see.. but pre-sales and salesman, and industry leader, all over the country. I make a small theory about this, because most of their product are based on...

Community

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,...

Tech Tip #25 showed how to configure WildFly on Raspberry Pi. Tech Tip #27 showed how to setup WildFly on two Raspberry Pis in managed domain mode. This tech tip will show how to setup a WildFly cluster over those two hosts. WildFly supports mod_cluster out of the box. There are several advantages of mod_cluster: Dynamic configuration of httpd workers Server-side load balance factor calculation...

They are organized and supported by the community and meet on a regular basis to discuss new technologies, development methodologies, interesting use cases, and other technical topics. The common goal is to provide education, help, and social events for the community and to promote open source....

Testing

Behaviour Driven Development is an increasingly popular Agile development practice that turns testing on its head. It turns automated acceptance testing from a verification activity, done once the development work is done, to a specification activity, with tester involvement starting from the word go. In this talk, we will look at how Behaviour Driven Development radically changes the traditional...

Behaviour-driven development (BDD) started as an improved variation on test-driven development, but has evolved to become a formidable tool that helps teams communicate more effectively about requirements, using conversation and concrete examples to discover what features really matter to the business. BDD helps teams focus not only on building features that work, but on ensuring that the...

Web Applications

I’m happy to report that the 2014 edition of the Web Framework Smackdown is shaping up to be a good one. This year we have a solid lineup, and for the first time we are going beyond Java with the inclusion of Misko Hevery representing AnguarJS and Pete Hunt representing React. Representing a more Java-centric approach to UI we have myself (representing JavaEE and JSF) and Joonas Lehtinen...

J2SE

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...

Programming

Unlock productivity is one of the bigger concerns for any person taking management role. However, people rarely agree on the best approaches to improve performance. Over the years, I have observed different managers using the opposite practices to churn out best performance of the team they are managing. Unfortunately, some works and other don't. To be more accurate, what does not increase...

Recently, there is a heaty debate regarding TDD which started by DHH when he claimed that TDD is dead. This ongoing debate managed to capture the attention of developers world, including us. Some mini debates have happened in our office regarding the right practices to do testing. In this article, I will represent my own view. How many kinds of tests have you seen? From the time I joined industry...

Databases

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...

Accessibility

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. Or maybe your mind turned to even more pressing problems with the site - maybe it doesn’t render correctly on mobile, or no updates get pushed into social media...

Deployment

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...
