Jdeveloper extension for JavaFX

Written by Aminur Rashid
Saturday, 20 February 2010
JavaFX is an expressive rich client platform for creating and delivering rich Internet experiences. More on JavaFX can be found at http://javafx.com/. JavaFX was the Official Rich Client Technology for the 2010 Winter Games. [http://www.oracle.com/us/corporate/press/049166]. I forsee the technology getting a push from Oracle specially after the Sun-Oracle merger. Infact I have read somewhere that JavaFX will be same to java Swing, what JSF was to Struts. And it was surprising to find there is no support in JDeveloper currently for JavaFX. (Offcourse now with Sun deal, Netbean with JavaFX support goes to Oracle but still for the lovers of Jdev its missing.)

Using oracle graph/bi graph without datacontrol bindings

Written by Aminur Rashid
Friday, 28 August 2009
Oracle had this excellent graph utility in the earlier releases of Jdeveloper. It was Bi-graph, which user can use to represent the data in graphical forms. This has been replaced in JDeveloper 11g by DVT component. However, the new Faces DVT component forces user to use Faces components, which may not be a requirement always. Neverthless, both the components (old BI graph and latest DVT components) are closely tied to the Datacontrols. What if user has Hibernate at the server side and want to use these components. The writeup, descibes one of the different ways, to show the data using BI Graph. The IDE used was : Oracle Jdeveloper Idea is to create an oracle.dss.thin.beans.graph.ThinGraph object in the background, set the data from any datasource (dummy data in this example), export the graph as image, and show in the JSP Be first to comment this article Add as favourites (94) \| Quote this article on your site \| Views: 911 \| E-mail

JDeveloper - Productivity with Choice

Written by Aminur Rashid
Tuesday, 07 April 2009
The team at Oracle has launched JDeveloper 11g Update 2 on OTN: http://www.oracle.com/technology/software/products/jdev/htdocs/soft11.html The release notes are here. Any Java Developer, reading this post, must try out this excellent development environment that simplifies the development of Java-based Applications. The launch also made me remember this new Datacontrol called Placeholder datacontrol, bundled since 11g Release 1 of Jdeveloper. Placeholder datacontrol supports UI-First Development process and helps the UI-Designers. UI designers can use placeholder data controls to create page layouts and page flows without the need to have real data controls available. These placeholder controls can be loaded with sample data to realistically simulate application execution for design evaluations. When the real data controls are ready, the UI components can be easily rebound to complete the application. To learn more about Placeholder datacontrols from oracle, visit the Oracle Docs.

How to detect proxy while connecting a url

Written by Aminur Rashid
Wednesday, 01 April 2009
When I started learning Java (infact I still am) I was stuck in assignment to open the net connection, which was outside our institute firewall. The document at Sun's website explains in depth the traditional, as well as the latest way (Use of Proxy class/Proxy Selector)to use Proxies to connect to a network. To refresh what I used, here is the code using the traditional method. Be first to comment this article Add as favourites (127) \| Quote this article on your site \| Views: 433 \| E-mail

Ctrl-shift-F1 in Swing Applications

Thursday, 26 March 2009
To see the hierarchy of a components in a swing application, one nice way is to type `ctrl-shift-F1`. Typing ctrl-shift-F1 displays the GUI hierarchy shown below: javax.swing.JFrame[frame0,100,100,297x436,invalid,layout=java.awt.BorderLayout,title=JTree
