Kiva FX- JavaFX Application using Kiva API
I was one of the earliest people to have explored the Kiva API. But then i couldn't do anything useful out
of it. Few days back it just flashed to me why not create a JavaFX Application which makes use of the Kiva API and also provides fair bit of usefulness. I sat down and went through the API again to check what all it provides. Then i came to a conclusion that let me create some application which the lenders can make use of, say to track the entrepreneurs they have funded. I kept the features limited so as to avoid too much of HttpRequests and Parsing of XML. I spent 3 days of non-stop coding to complete the application. Most of my time was spent on aliging the UI and different components. Hopefully JavaFX gets a JavaFX Builder soon (With the UI support). But to be frank the various features of JavaFX made the application development easier. This would have been more heavy and time consuming if developed using Java Swing. I really liked the "bind" feature of JavaFX. We can bind the data sources to different UI components and let JavaFX do the job of updating the view. I had problems in using the Effects and also few javaFX controls. So i stuck to more basic fade transition and the gradients.
More details can be found here.
Launch the application here.
Do drop in your comments and let me know how i can improve the application.

Simple JavaFX Delicious RSS Feed Reader
I had long wished to create a RSS Feed parser which would parse the Delicious bookmarks feed. This time I sat down to code one! But ended up with a simple application. Nevertheless it was a great learning experience for me. The source code can be downloaded from here.

Building DLLs using Cygwin
I was going through JNI which i required for writing agents for JVMTI. JNI requires the native implementation to be compiled in to the native library, DLL in this case as i was running on Windows using Cygwin. I was searching a bit for creating DLLs for the C implementation and found this useful link here. The lnik has lot more information about building and using the DLLs. I thought of sharing on this post the building DLL part alone.[Read More]Posted at 04:03PM Jun 21, 2009 by Mohammed Sanaulla in Java | Comments[0]

Opening URL in a browser from JavaFX Desktop Application
I searched a bit for opening URL in a browser window using Java and came across the following API:
java.awt.Desktop.getDesktop(new URI ("www.google.com" ));
But then when i tried to run the application using this code snippet i got error both in Eclipse 3.4 and in NetBeans 6.5. Eclipse atleast showed the class Desktop in its Intellisense but NetBeans did not do even that. But when i tried to run the same application from the command line it executed with out any exceptions. No idea wat may be the problem. Anyways i figured some way to open a browser using the Hyperlink control of JavaFX. For this i made use of a custom class UrlOpener-
class UrlOpener{
public void openURL(String url) throws Exception{
java.awt.Desktop.getDesktop().browse(new URI(url));
}
}
Now we make use of this helper java class in our JavaFX script hyperlink.fx. This script contains a TextBox control to enter the URL to open. The user can either open the url by clicking on the Hyperlink or by pressing enter from the TextBox control.
import javafx.scene.Scene;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;
import javafx.scene.control.*;
var urlBox: TextBox;
var hyperLink: Hyperlink;
Stage {
title: "HyperLink"
width: 300
height: 200
scene: Scene {
content: [
Text{
content: "Opening a URL Demo"
translateX: 10
translateY: 40
font:Font{
size: 15
}
},
Label{
text: "Enter the URL"
translateX: 10
translateY: 70
width: 100
},
urlBox=TextBox{
translateX: 120
translateY: 70
width: 100
action: function():Void{
UrlOpener{}.openURL(urlBox.text);
}
},
hyperLink=Hyperlink{
translateY: 100
width: 200
text: bind "Visit {urlBox.text}"
action: function():Void{
UrlOpener{}.openURL(urlBox.text);
}
}
]
}
}
The screenshot:
I did not try the Applet version. Also this is not working when tried using NetBeans or Eclipse. Have to figure out why so. If there's an alternate way to open the URL via Hyperlink do let me know. I would be really greatful for that. This particular sample uses TextBox and Hyperlink control

JavaFX Barchart demo
Just finished going thru the BarChart api. Managed to write a simple sample application which shows using BarChart3D. It doesn't take any real time data. Actually the samples written by Vaibhav here helped me a lot. Will actually go thru the RSS Feed API and try out fetching some real time data. Here's the screenshot of the application:
Run the JNLP file here.
Download the source code here.
