I was going through the documentation of Spring Roo, version 1.0.1 while preparing a talk for JDC 2010 about the Spring Roo .. No need to mention the Roo is awesome, amazing and not Magic :-) Ben Alex , Stefan Schmidt did a great job really in this project. Smart architecture! "The automated startup-time scan is also very useful as you upgrade to newer versions of Roo. Often a new...

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. Forewords 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. The...

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...

Over the past decade, OpenSource became a big hype. At the peak of the hype, big stakeholders like IBM, Oracle and Sun (and even Microsoft and SAP) turned a lot of their previously proprietary code into OpenSource. While they tell us that they do it because they are so noble and like to exploit the community's knowledge, typically the open sourced software is only for free in part or is still...

This new refcard discuss the following items:   Introduction to GlassFish application server v3. GlassFish v3 versions, installation and directory structure. Glassfish v3 daily administration tasks. Glassfish v3 Restful interface for monitoring and administration. GlassFish...

I would like to show you how you could extend your javadoc to include samples directly into the javadoc without extra work. What I don't like about javadoc is the lack of code sample. Something is can be hard to find the starting point of a new framework. Let's show a example, it will be easier to understand, and so simple. [prettify]

GUI

In my famous company innoQ I currently have the opportunity to work on a real cool tool: Bundle-Bee. It claims to be able to take any OSGi bundle and distribute the computational load to an ad-hoc grid (e.g. all machines in an office) without special setup or configuration. We just released version 0.5.3 which is still very restricted and far from feature complete - we don't even...

J2EE

According to the PrimeFaces website, "PrimeFaces is an open source component suite for Java Server Faces featuring 70+ Ajax powered rich set of JSF components. Additional TouchFaces module features a UI kit for developing mobile web applications.". Since it is an OpenSource JSF implementation that is very close to releasing JSF 2.0 compliant components, I figured it was time to try it...

Hope you have read my last blog on using SailFin CAFE with web applications. Mohit has added an entry on how to enable Communication capabilities in JSPs. The approach is exactly same except that the CommunicationSession object is available as a session attribute. Take a look!

EJB

In the past few month several Java EE 6 related JSRs (Java Specification Requests) have been finalized. The final ballot for them ended on November 30 and all were approved. Today, December 10, 2009, Java EE 6 and GlassFish v3, THE reference implementation of Java EE6, are released. Four and a half year after the release of Java EE 5 we enter the next Java EE era. GlassFish v3 is the first...

NetBeans 6.8 released coordinated with GlassFish v3 today. NetBeans 6.8 can be considered a fine step ahead of NetBeans because Sun is officially supporting the NetBeans RCP platform as a product from now on. NetBeans 6.8 features are as follow: Java Enterprise Edition 6 support Web Projects with JavaServer Faces 2.0 (Facelets) JavaFX 1.2.1 support Kenai.com: Connected Developer Full support...

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...

Open Source

The scoop of these days is the “climagate” - a hacker stole and then published on the web a bunch of e-mail messages and documents from a British university and those documents allegedly affirm, among other things, that some data sets used to proof the Anthropogenic Global Warming (AGW) have been “massaged” way beyond the legit terms. Depending on the country you live in, you'll find a widely...

Preparing the architecture for a software system means not only...

Servlets

So far I have described how create server applications that handle call, conference and IM using SailFin CAFE. In this edition lets take a look at how to add communication capabilities to web applications in a (very) simple way. I like to start with the code. So, here is some code that implements making a phone call between two parties from the web application. package my.test;import javax....
