Java Enterprise

It's been a while since I've blogged last (ok, it's been a year), but I recently came across a question that I have a little insight into, and I thought I'd tackle it briefly. The question was simple:  "How do I test my JSF application?" I've used two different test frameworks to do so, and besides being two of the most popular, they also offer a good example of the two different patterns used...

While we work on the release notes and get ready to prepare a release bundle, I wanted to push this quick blog entry out as soon as I could. I just committed the integration of Mojarra 2.1.0 build 10 to the GlassFish 3.1 HEAD, it will be in the next promoted build of GlassFish. If you want to get the Mojarra installation standalone, you can either wait for me to post it on the official Oracle...

End of the last year and beginning of this I've spent trying to get Magnolia work with ModeShape. There were issues with both of the apps. On one end, Magnolia had issues with the Modeshape session data refresh strategy, on the other one, Modeshape was sometimes stricter then JCR spec required it to be when it came to queries. All of those were elementary issues that were relatively easy to...

Hello guys, I have just released a plugin for Scripting in Grails. It basically let you create Groovy scripts as CRUDs, so you can use them for dynamic behaviors. This is a first release, so feel free to send feedback for future improvements. http://www.grails.org/plugin/scripting If you want to learn more about how to create plugins for Grails, check this link.

This blog shows how to programatically change the log levels of a particular logger in Embedded GlassFish. I did a search on the internet for information on how to change the log levels of a particular logger in Embedded GlassFish. The only information I could find was http://docs.sun.com/app/docs/doc/821-1208/gjlfe?l=en&a=view which requires changing $JAVA_HOME/jre/lib/logging.properties....

Apache maven is supposed to solve the classpath hell; or so I´ve been told... Started using maven 2 in a multi-pom project. One of the requirements is to be able to deploy EAR files to Weblogic. After looking around it seemed like the most stable way of doing this with maven and Weblogic 10.x is to use the Weblogic Ant task. Not ideal since we are migrating away from Ant, but still okay. So...

Last week, I sent a code review request to the Mojarra dev list. As you can see, no-one responded, but when a good friend and longtime Mojarra comitter (the winner of this contest) popped into the JSF IRC chat room, I asked him to review the changebundle. We played IM tag for a while and when he finally caught me he brought a potential issue to my attention. The issue hinges on the answer to...

As you may have noticed, Oracle’s java.net collaboration site is undergoing an infrastructure provider change. More details on this can be found on Sonya Barry’s blog. For Mojarra JSF, this transition is only partially complete. I plan to publish a new entry (and update the Spec and Mojarra JSF FAQ files) when it’s all done describing everything you need to know to...

Automated functional tests are key to ensure the quality of large applications in incremental development processes. In contrast with unit tests where each test is supposed to be independent from the outside environment, functional tests are really integration tests: in order for them to run properly the process must start from a well known state. The majority of enterprise applications use a...

I had originally planned to write a blog post per day during JavaOne 2010. That being my first JavaOne I was of course completely unprepared for the hectic routine of sessions, meetings, parties and more sessions. I wrote blog posts in the first two days and disappeared ever since. I am alive, well, and back to Brazil. I had a terrific time in San Francisco where I got to meet a lot of...

Java Desktop

Often code has a bad smell, then it gets time to replace custom lines by common patterns. Sometimes it even makes sense to even replace a single line of code by a class just wrapping that single line (which actually increases code size), if that makes readers better understand what the code does. Unfortunately often such patterns are publicly known but do not exist as ready to...

We are making progress on the next release of Leonardo, an open source desktop Java drawing program. One of the key features scheduled for the next release is a webservice that lets users save and share reusable symbols they've created. For example, someone could create a set of GWT mockup widgets, then share this set with others. The challenge I face is that I'm mainly a client side developer....
