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,...

The usual Java EE BoF at DevoxxUK was another chance for community members to meet and discuss the past, present, and future of Java EE. The gathering happened on the first anniversary of Java EE 7 and so allowed us to focus on what happened in the past year and start focusing on what’s expected from Java EE 8.
Here are some notes:
Meetup started with the usual pet peeve of no official Java EE...

JBoss Tools is a set of plugins for Eclipse that complements, enhances and goes beyond the support that exists for JBoss and related technologies in the default Eclipse distribution.

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...

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...

In JSF you will see people from time to time use rendered="false". But what does it mean?
Well, because in JSF the actual request is page based it builds up a representation of the page when the page gets loaded. When it is building up this representation it builds up the entire page, even the parts that are not going to be rendered.

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...

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...

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...
