Modularity is the essential design and implementation consideration which every software architects and designers should have in mind to get an easy to develop, maintain and extend software.
GlassFish is an application server which highly benefits from a modularity system to provide different level of functionalities for different deployment and case studies. GlassFish fully supports Java EE...

Christmas holidays is one of my favourite moment in the year, I have time to see my relatives, read books, play with my kids and hack a little bit.
I think I don't like the most in the strawman proposal is that the syntax for function type and for lambda literal reuse the same symbol '#'.
It's something that I've observed when teaching C. The C syntax use * when you...

We can't live without Javadoc, but even if it useful, it's not complete. One missing thing is UML within the Javadoc.
To add UML to your Javadoc, is quite simple. You need to add Graphviz into your maven build.
First you need to download and install Graphviz. Go there Graphviz
After that you should add the variable GRAPHVIZ_HOME (that point to the installation folder) into your system.

I am very fond of FindBugz (indeed it has found its way into the QA process of most projects I work on....). When visiting the site to check Eclispe 3.5.2 compatibility I found they were working on a new tool.
Indeed a very interesting tool.
Looks like they have a specific tool for browsing the output of a findbugz; and sifting through the results in order to mark each issue. They have an example...

We use the Java programming language. If you want to do a similar task, have a closer look at our work. Since ODT is part of the ODF standard, which is well defined, XML-based and easy, this task should not be that complex - an so it is.
The work was done by Tim Schäfer, he used the ODFDOM API as an abstraction layer for ODF.
Have a look at our work at...

I just updated the Cejug-Classifieds Project to support Maven 2 builds and I added some new features, including a Shell Script able to configure the resources and also to deploy the the application in the Glassfish V3. The script creates all Java EE resources required by the application, like the DataSource, the JavaMail connection and the JMS Queues. In the next sections I will describe how to...

For meanwhile more than 25 years I am writing computer programs. More than a decade I spent with programs accessing databases, virtually always relational ones. I soon learned that this is rather hard work. Not only that you need to know about the theory behind RDBMS iself, but also you need to know the technical APIs (like ODBC, ADO, RDO, JDBC, JDO, JPA, CMP, ...), the structure of...

As I noted last week, the java.net Java Tools Community is attending and tweeting from the Campus Party Brasil event this week. Now, in my post last week, I pretended the event was just going to be a fun-filled affair. Now that the tweeting has begun, I decided to check in on the feed. Here's a sampling of the Java Tools tweets from Campus Party Day One (in time forward order):
You can watch...

I've finally managed to produce the Windows installer for Hudson, as originally raised by Håkan Reis. Please try it out and let me know how it works.
This one took much longer than the installer for any other platforms, and while I normally think of Microsoft technologies very highly, Windows installers and WiX are a real disappointment. For example, you write the description of the...

Given that Maven is much more complex than Ant, and it dinamically resolves dependencies, people are right to be concerned with having deterministic builds. But the vast majority of problems are solved by just three good practices:
version everything, including all Maven plugins
run once in a while mvn dependency:go-offline, that will download all the required stuff
routinely use mvn -o (offline...

This is a very basic review of active and available open source Java EE Application servers and Servlet container (Web containers) to let the community know which active containers are available and what is the general status of each container. The article can simply act as a start point for anyone need to select one of them for later use in development or product. Detailed comparison of these...

I recently got pointed to that link: http://java.dzone.com/news/ant-18-scanning-leaves-171
I read the news with some pleasure reminding me that I still like Ant based builds very much over Maven in many cases.
Of course there are a lot of well maintained projects on the web that work very well with Maven. You never know how many enthusiasts-hours have been spent to make that happen. However, in...

JavaFX 1.2.1 support

For many years I am using XSLT now for a lot of tasks in both, development and runtime environments: Source generation, creating HTML from XML data, or even rendering SVG vector graphics from XML finance data. But what really bothered me was that the XSLT transformer contained in Java (even in Java 6's latest release) was just able to do XSLT 1.0 but not XSLT 2.0. XSLT (and XPath) 2.0 comes with...

Happy New Year folks!
In 2002, I wrote a highly specialized, very small Q&D tool for my brother to support him in his oncological doctoral's practice. They are three physicians sharing a common room with some unique ultrasonic device. They needed something showing them at their desk wether the room is available or is currently occupied by somebody else. The name 'dokma' is a German pun....
