Java EE 7 just around the corner

2013-06-02T20:03:00.003+02:00

Just a little more than one month ago the latest version of the Java EE specification got it's seal of approval and in just a few days the reference implementation (Glassfish) of Java EE 7 will be released to the public. So you know what you should look forward to let's have a look through the stuff that I find most exciting. JSF 2.2 Even though we're talking about a minor update JSF 2.2

Make JSF your friend again

2012-04-08T08:58:00.002+02:00

Let me start by saying that I quite like JSF so I have spent a fair amount of time using it, so I know well enough what’s good and what’s bad about it and while I don’t think it’s god gift to Java Developers, I believe there is a definite pro in using a framework based on a specification that all the players in Java EE have to support. What I find interesting lately is that I still get all the

JAXB, wsimport and the dreaded xs:date in a simpleType

2011-10-03T06:00:00.000+02:00

Every now and then you will have a Web Service that defines an operation's parameter as a complexType that contains a list of reusable simpleTypes which in turn have restrictions such as xs:int or xs:date. While this is a good idea for the sake of reusability and clearity to the business many of us encounter the problem that JAXB doesn't correctly infer the correct serialization for these

Fedora as IPSEC/L2TP VPN Server for Mac and Android

2010-11-02T22:53:00.001+01:00

Now this is probably one of the most unrelated posts one could think off (considering my other posts about programming) but I just have to write this down because I am almost a 100% certain that other people have exactly the same problem. Recently we reinstalled one of our office servers and we finally wanted to have a IPSEC/L2TP server as both Android, Mac and iPhones support it natively. The

E-Mail to Steve

2010-10-26T10:28:00.001+02:00

I can't believe how quickly the number of supports on PetitionSpot.com grew once Rick Ross from DZone posted the link to it on DZone's Twitter feed. My initial goal of 10.000 signatures is not that far away and to be honest, I was more less guessing what a "good number" of supporters would be. Having reached almost 4000 signatures already, I have now written a letter to Steve Jobs and I want to

Java for Mac, not Oracle's business [UPDATED]

2010-10-23T19:06:00.005+02:00

As many of you, I was surprised to read that Apple would be phasing out Java from Mac OS X and Steve Jobs is basically trying to push the responsibility over to Oracle. It didn't take long, but within hours message boards were filled with posts about this. The reason? Quite simple, many of those that buy a MacBook Pro, are Java Developers to begin with! They bought a Mac because they like the

James Gosling leaves Oracle, so what...

2010-04-10T22:52:00.001+02:00

You've probably heard the news already, but according to his most recent blog post, the father of Java is leaving Sun/Oracle. Personally, I believe that this may be a blessing in disguise. Gosling has always been the embodiment of a typical "techie" and getting sucked in to Oracle's all out corporateness probably isn't his thing. We will see, but I am already looking forward to reading the news

JavaOne 2010

2010-01-28T20:10:00.000+01:00

Great news my fellow Java-coders, Oracle announced that there will be a JavaOne 2010 after all. However, don't start packing your bags quite yet. JavaOne will be part of Oracle's yearly Oracle World/Develop conferences and thus it won't be in spring as we've gotten used to but will be rescheduled to September 19-23 of this year.

IntelliJ IDEA 9 is just around the corner

2009-10-15T23:26:00.000+02:00

Great news! It seems that IntelliJ IDEA 9.0 with an extended list of features is just around the corner; however, the greatest news of them all is that Jetbrains will be releasing IDEA as open source! Amongst the new features which will come in handy (at least for me) are: Support for Java EE 6 Support for Java SE 7 An improved Griffon/Grails plugin Android development-support For an extensive

One more "Architect"...

2009-06-08T17:32:00.000+02:00

This isn't big news, really. Still, I'd like to share my latest accomplishment. As of today I may call myself Sun Certified Enterprise Architect for Java EE 5.In fact, it's quite funny that I actually feel a little proud of myself... after all, I've real-world experience being an Architect for fairly complex mission-critical applications.Anyway, despite the proven fact that certifications do have

Happy Birthday!

2009-06-04T20:57:00.004+02:00

Bake a cake, take out the forks, brew a cup of coffee and light some candles! This month we are celebrating the 40th birthday of the UNIX operating system as well as the 50th birthday of the COBOL programming language.These two technologies affected the business world like few others did and to this very day we are still relying on Unix (and Unix-like) installations for our business critical

Are we Java Programmers done for?

2009-04-30T16:34:00.004+02:00

I do realize that the continuous stream of Oracle+Sun articles might bore you, however, I feel that I have to add my 2 cents to the subject as the last couple of weeks have been fairly interesting in my professional life.It started out when one of my former colleagues asked me to check a popular Swedish page on IT. The first article on the page put me in shock: "Oracle buying Sun", it said in

Caller identity propagation in JBoss

2009-03-11T20:43:00.012+01:00

Recently I was asked by a client of mine how they would go about to propagate a JAAS Principle from one layer of their Java EE application to the next. Basically, the problem they had was that they needed to get some information about the logged on user from the Web Layer to the EJB Layer. Initially I was surprised because I thought that it is rather self-explanatory... apparently, if you haven't

New stuff for JBoss in the Maven EAR plugin

2009-02-22T16:33:00.005+01:00

It's been a number of years ago that I contributed to some open source project. To be more accurate, it was some four years ago that I submitted some bug fixes and features to OpenSymphony's WebWork 2 (which is now known as Struts 2.0).After all these years I once again modified an open source project to do something I needed, and this time it was Maven's EAR Plug-in.On release of version 2.3.2,

Adding endorsements to Maven's plugins

2009-02-09T14:10:00.008+01:00

Since Java 1.6 a number of libraries come piggybacking with the JDK installation. These are namely JAXB and JAX-WS, amongst others. Great in a way, however, if you previously built your project with Maven on Java 1.5, you may get worrying runtime exceptions when executing the build artifacts.If you, just like me, ran into these obvious class path problems you will have to tell Maven to endorse

Artifactory 2.0 on JBoss

2009-01-13T22:55:00.007+01:00

Today I ran into some trouble getting Artifactory 2.0 (a great repository service for Maven) to work on JBoss AS 4.2 (and EAP 4.3, for that matter). After some investigation the root cause of the problem was Apache Derby which comes packaged with Artifactory. It starts a JMX Management Server which conflicts with JBoss and depending on what platform and version you try to run it on you get

Happy holidays and a prosperous 2009!

2008-12-24T13:10:00.001+01:00

Honestly, I thought I'd manage to release another article in December, however, this hasn't happened. Anyway, I want to wish all my readers happy holidazs and a - despite recession and financial crisis - a prosperous 2009!A couple of articles which I started to write and which you will be able to read in 2009 are about OpenID, .NET and J2EE interoperability as well as building your own process

Are we there, yet? Yes, we are!

2008-12-05T20:37:00.007+01:00

After waiting for such a long time Red Hat's JBoss division has finally released the JBoss Application Server 5.0 and for me personally, it's a feeling of better late than never.While you are downloading Red Hat's newest baby, you may want to know what's new and hot in the 5.0-release...First of all, Red Hat provides an updated JMX console and shortly there should be an update for their embedded

The cost of the 64bit JVM

2008-11-06T08:17:00.004+01:00

Running out of heap is never fun, and as applications grow, both in terms of usage and size, this has become a problem for many companies hosting big applications. A number of years ago, when EM64T/AMD64/x86-64 (or whatever you want to call it)-capable servers entered the ring, the most common way to overcome the 1,n to 2,n GB limit (depending on the OS) of the 32bit JVM was to install a 64bit

The new and improved Java SE

2008-10-16T22:46:00.003+02:00

Great news! The long awaited Java SE 1.6u10 has finally been released.Besides a long list of bug fixes, this new version also sets the stage for JavaFX by making Java modular. Users don't need to download the entire JRE, instead, only the modules needed for your Applet (i.e. a JavaFX RIA), will be downloaded. Should any of the Java applications executed on the user's machine need additional

Reliable monetary calculations

2008-10-07T16:02:00.014+02:00

As you all probably know, reliable and correct monetary and scientific calculations in Java aren't as easy as it may seem. Many Java newbies and in some cases even intermediate Java developers, frequently use the data type double for monetary calculations. What's worse, for scientific applications there is no support worth mentoining, at all.Now, if you build a small scale web page, you may never

Java EE Profiles ... aka ... Problems Ahead

2008-09-14T07:21:00.002+02:00

Today I want to share my thoughts about the upcoming Java EE 6, or more specifically, one part of the JSR-316: Profiles.Up to this day we've gotten used to the fact that if we are using a J2EE/JEE-compliant server, we can also use the features Java EE provides. In the future, this is not so clear-cut. You may find yourself coding a Java EE-app and realize too late that you accidentally slipped in

Groovy for Java Developers

2008-08-21T20:15:00.003+02:00

Last month I attended The Server Side Symposium in Prague. After listening to Ted Neward's session titled The Busy Java Developer's Guide To Scala I got inspired to produce a similar presentation on Groovy.After writing a couple of slides, something struck me: "Could Ted Neward already have done this?" Thus, I checked Google and I was pleasantly surprised to find that indeed, he did!If you want

KDE 4.1 hits the "shelfs"

2008-07-29T17:05:00.007+02:00

If you use Linux and happen to use KDE as your window manager, you may be excited to hear that KDE 4.1 has finally been released.And if you run Kubuntu, you can already upgrade to KDE 4.1 by performing these simple steps:Type sudo vim /etc/apt/sources.listAdd the line deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy mainSave and exit (:wq! ... just in case you are not a "vimmer")

Google versus Microsoft

2008-07-27T14:54:00.006+02:00

Now that headline probably caught your attention. Nevertheless, the content is not quite as exciting, but it's nonetheless a funny and somewhat ironic observation that I made and that I want to share with you.A couple of days ago I watched a webcast from the Google I/O developer days where Aaron Boodman from Google talked about standards and HTML 5.0 in Google Gears.After watching it, I decided
