Application Servers have changed a lot: consuming less memory, being faster at startup time… Now it’s time to change the way we package our applications: from Ears, to Wars, and now to executable Jars. This is what I explained in this “Just Enough App Server” talk I gave at few conferences lately. So if you want to know more about Application […]
The developers’ world is a mixture of evolutions and reinventing the wheel. When I was doing EJBs 1.0 back in 1998, I was doing Micro Services. But I had to wait 2014 for someone to give it a name, and 2016 to see it officially arriving in Enterprise Java. So here we are: a Micro Profile has been announced for Enterprise Java. […]
Updated Thanks for your comments. I’ve added Undertow to the test ( “Servlet-Only Distribution” on the WildFly download page), corrected some mistakes, but more important, I’ve changed the memory benchmark: I now take a memory usage measure at startup, I then perform GC and wait a bit for memory to stabilize. This gives a nice min and max memory usage. Damn, I’ve […]
Are you going to JavaOne? Well I’m not! But instead I’ll be doing some talks in October and November in Europe and Morocco. Four years ago I toured central Europe giving CDI talks. Next week I’ll start another tour with CDI and Forge talks. Here is my schedule : Tuesday 20th of October – JUG Frankfurt (Map) : Talk on JBoss Forge […]
If you are interested in JBoss Forge, you should check out this 50 minutes talk I gave at Devoxx UK. You can also get the slides and the code. Talk in English Slides 50 new features of Java EE 7 in 50 minutes from Antonio Goncalves
Who cares about toString performance? Nobody! Except when you have huge amount of data being processed in a batch that does plenty of logging using toString . Then, you investigate why it’s slow, realize that the toString method is mostly implemented using introspection and can be optimized. But first, let’s have a look at the Javadoc to remember what a Object.toString should […]
If you want to learn about CDI you can read the 4 articles I wrote in the Java Magazine : Part I : Using strong typing in dependency injection (May/June 2015). This article covers basic dependency injection with CDI, @Inject, Qualifiers and Alternatives. Part II : Integrating third-party frameworks (July/August 2015). Covers Producers, InjectionPoint API and Diposers Part III : Loose coupling (September/October […]
