JCard kit is a solution for Java Card development, supporting developers using Eclipse or NetBeans with supported smart cards or simplely using a card simulator.

For the Messaging chapter in San Gria, I needed a good example for our Twitter clone, hubbub. The one I ended up with was a simple Jabber gateway.

In the same vein as my recent article on how to know the variables which are bound or not in a script, a user asked how he could list in order the properties defined in a class. Unfortunately, using MyClass.metaClass.properties won't guarantee the order in which properties were created.

There were significant improvements in code completion for Groovy in NetBeans during the last few days. The code completion is now more accurate and reliable.

Here are some Swing links that you might have missed during the last week:

Time and time again, users complain about an application crashing on them or otherwise not working. They don’t provide you any info and it’s hard to repeat. You check out the log, but there’s thousands (or millions) of entries and you have no clue where their error occured. Worse, if you are deploying a RIA, the log may be on their computer and not available.

A brief overview of Behaviour-Driven Develpment with easyb, a new BDD testing framework for Java and Groovy applications built on Groovy.

The main purpose of the Java Wikipedia API (Bliki engine) is the rendering of the Wikipedia (aka Mediawiki) syntax into HTML.

With three proposals vying for inclusion in Java 7, understanding closures and the arguments for and against their inclusion in the Java language is essential.

Through the previous articles (Part 1 and Part 2) we've covered the Jasper introduction, architecture, environment, and finally we managed to run a sample report. Today we're going to work with visual report design tools and enhance our sample application to receive run-time parameters.

10 Different charting solutions for the web using JavaScript, Flash, Silverlight, and Java. Surprisingly no mention of Google Charts.

Welcome back to Java Reporting series. For those who didn't read the introductory article; have a look here before we get started. Today we're going to have a quick tour in JasperReport architecture, development lifecycle, report definition files, and finally we're going to set up our environment and start work in a sample application.

This Dilbert comic strip reminded me of a drawing I did a while back to try and explain the critical nature of our bug tracking system, and how all the various systems we have and use connect back to the bug database. Granted, right now the JDK team is using an internal bug tracking system (that will change someday), and the visibility is limited to what you can see via http://bugs.sun.com/.

The following documentation has been updated to reflect the latest stable drop of 5.0dev: * Skin overview document, along with sample screenshots and code snippets from existing core Substance skins. * Skinner primer that describes how applications can use Substance skin APIs and painters to provide custom application painting that is consistent with core Substance visuals. * Documentation of gradient painters, decoration painters, highlight painters and border painters. * Documentation of watermarks. ...

In this presentation from QCon San Francisco 2007, Jason Rudolph gives an overview and demonstration of Grails.

A quick tutorial on XML processing using Groovy.

There are a number of similar JDBC-Excel driver out there, but most seem to be nearly abandoned. Moreover, they all either use native pieces, are read-only, or do disconcerting things with in-memory databases, none of which work for me. SQLSheet is a JDBC driver which allows you to interact with Microsoft Excel spreadsheets using SQL statements.

Recently many blog postings related to NetBeans with Groovy and Grails integration appeared on groovyblogs.org. See Guillaume Laforge's Groovy / Grails support in NetBeans and GlassFish blog entry for a complete summary and links to related postings.

One View to Highlight them All, One View to Filter them All and in SwingX Bind them. Centralize the filtering and highlighting in a View that is dispatched in all his registered components.

Auto-scrolling is a feature that can be found in most mainstream modern applications. Pressing the middle mouse button transfers the application into the auto-scrolling mode. In this mode, moving the mouse down starts scrolling down the contents even when the mouse is no longer moving. This article introduces an effective approach to achieve auto-scrolling in Swing applications.

When you create a new project you can specify the source level and the JDK to use with it. This is an important fact because depending on the source level the GUI builder matisse will use new classes available in JDK6 or not. This must be taken into account if you want to create GUIs that must run in older version of JDK and not only in JDK6.

Hello guys, just to point you out this new update for Java SE 6 update N b13. It works flawlessly.

While developing around now or then one wants something printed out at the console of his/her IDE. Well, with Groovy, it's easy: println "Hello World!". But when it comes to some serious development and logging you must meet some requirements

The literature on Drop Down Buttons in Swing, as this search of Google reveals, is not extensive. And what there is is dated. Here I give a brief overview of the existing resources and... provide a completely new and undocumented alternative that has existed since almost one year ago.

Mike Brunt, of Alagad, discusses how he tuned an application by working with the myriad of JVM settings. Examples complete with charts and config settings.
