Quidquid latine dictum sit, altum viditur…Script to Installing JavaFX Compiler
Posted July 16th, 2008 in englishRight in this moment you can choose between three options to develop JavaFX:
- Use the old version of JavaFX, interpreted. Not recommended.
- Use the JavaFX Milestone 3. Little bit old but more stable.
- Use the JavaFX Continuous Build. Is more dangerous but give us fresh builds.
I did this little script to download the last version of JavaFX continuos build and install it for you.
#!/bin/sh envfile=$HOME/.bash_profile #download and unpatch the last build of JavaFx mkdir jfx cd jfx wget http://openjfx.java.sun.com/hudson/job/openjfx-compiler/lastBuild/artifact/openjfx-compiler/dist//*zip*/dist.zip unzip dist.zip rm dist.zip #set files at bin folder as executable chmod +x dist/bin/* #add those executables to the path echo "PATH=\$PATH:`pwd`/dist/bin" >> $envfile
Save this script as install_jfx.sh and execute it. Probably you want to execute it at you home directory. If you want to install JavaFX to root change envfile for /root/.bash_profile, if you want to install to all users change for /etc/profile. I tested this script successfully on my Ubuntu 8.04.
After that open a new terminal and try to see if javafx, javafxc and javafxdoc are available. You can test your enviroment with this simple program.
import javafx.ui.*;
import java.lang.*;
Frame {
visible: true
content: FlowPanel {
content: Button {
var n = 0
text: bind Integer.toString(n)
action: function() {
n++;
}
}
}
}
Save it as Counter.fx, compile with javafxc Counter.fx and so execute it with javafx Counter.fx.
To know more, take a look into the preliminary JavaFX API or in the article Using JavaFX GUI Toolkit.
September, Sun Tech Days Brazil
Posted July 9th, 2008 in english
As seen in the Sun Tech Days page, the Sun Tech Days Brazil will happen this September. In a few days we can know exactly the day the event will occurs. Probably we CEJUG will prepare a parallel event and see live the event in São Paulo by video stream. ![]()
Event Review: Comsolid
Posted June 30th, 2008 in englishThis week I did another presentation outside my city. This time it was at Maracanau in the Consolid, a open source and digital inclusion event.
My first presentation was about ZFS filesystem and how you can take benefits from it like pooling storage and self healing. I used as base for examples my last post on it, Trying to corrupt data in a ZFS mirror.

My next talk was about OpenSolaris. We had a lot of questions and interesting about this. We burned some cds with OpenSolaris 2008.5 and also distributed others versions of OpenSolaris like Solaris 10.
And my last presentation was a quick talk about high performance computing, a short version on that I already did before.
Was a interesting event mainly because the public was composed primarily by young students with few background on TI. It was a challenge to present some new concepts like pooling storage for those who aren’t familiar with filesystems management. I tried to keep my talk as simpler as I could and focus on daily problems and showing that you can avoid them with some open source technologies.

Event Review: JavaDay Juazeiro do Norte
Posted June 16th, 2008 in englishRafael Carneiro, Tarso Bersa, Rafael Ponte and me, after 8 hours of bus travel, arrived in Juazeiro do Norte to talk at the first JavaDay there.
- Rafael Carneiro talked about Java Certification.
- Tarso Bersa talked about Spring Framework for JEE applications.
- I talked about NetBeans 6.
- Rafael Ponte talked about JavaServer Faces.
We answered a lot of questions and gave lot of gifts. I also showed the Sun Academic Initiative, which they are already subscribed. We also showed several opportunities they can participate with CEJUG like free vouchers or a free travel for Belgium.
Some pictures we took. These ones during the bus travel. We saw a nice sunrise through beautiful landscapes.
We playing guitar hero.
The city have their own shopping with games, restaurant and cinema.
The main atraction at Juazeiro is a statue of Padre (Priest) Cícero with 7 meters itself and more 8 meters of base. Pilgrimage to this statue takes place in his honour every November, attracting thousands of followers. The city’s economy is highly influenced by those travelers devotes.
There’s a museum with several personal objects from Padre Cicero. People go there in order to thanks for miracles. If you got your a part of your body cured, of place there a wooden replica of that part of your body. If you got a car, you place a wooden car or a photo, and so on. There is thousands, maybe millions, of objects theres.
You can see all photos at Carneiro’s album or in my album.
