Some months ago, developers from Databyrån, Mercur, Artificial Solutions, the Swedish Defence Research Agency, and Björn Lundén Information were introduced to the NetBeans Platform at a training course in this street in Stockholm... ...which is where Artificial Solutions is found, who hosted the training. Here's a snapshot of part of the group, all from the various organizations listed above, some of whom flew in from Barcelona to attend the course: In fact, there were too...

As a new employee at Oracle, I've been reading & learning about Oracle tools and applications. Currently I'm learning about Oracle Insurance Rules Palette. It looks like this: There's a really impressive & lengthy tutorial about it here. In short, the Rules Palette is Oracle's insurance configuration solution.  It is a standalone application that can be used in conjunction with select Oracle Insurance applications.  TheRules Palette provides straightforward functionality...

Sometimes you'd like to register random annotations into the layer for an action. However, everything is currently predefined. Here's my proposal for how to fix that, note the section in bold: import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import org.openide.awt.ActionRegistration;import org.openide.awt.ActionReference;import org.openide.awt.ActionReferences;import org.openide.awt.ActionID;import org.openide.awt.ActionSupplemental;import...

Record your golf games on the NetBeans Platform via the brand new & free GolfCVS by Ulrich Mayring (click to enlarge): I'm interested in finding out whether the above is available as an open sourced application, in which case it could serve as a generic framework for various kinds of sport applications. One application that could share that framework would be Pursuit, a NetBeans Platform application for recording the results of cycling races (click to enlarge): In the generic...

Thanks to Jesse, here's a corrected & improved ChildFactory from a few days ago, using ChildFactory.Detachable so that you have addNotify/removeNotify to add/remove the LookupListener and thus avoid a memory leak, together with a createKeys/resultChanged that is simplified too. private class FirstLevelChildFactory extends ChildFactory.Detachable<ResultType> implements LookupListener { Result<ResultSet> resultRetrievedFromYahoo; @Override protected void addNotify() { ...

Here's the remainder of the app shown off in this blog yesterday (click to enlarge it): The app could be useful as a starting point for a newsroom application, i.e., an app for journalists. Reports come in over the wire via Yahoo (or AP or whatever), the journalists edit/extend/plagiarize them, then they're saved to a database. I'm going to upload it as a source sample to http://java.net/projects/netbeans soon.

Let's say the business requirement is that you need to create an app that drills down into a set of data. We'll simulate the scenario via Yahoo News. Using tools in the IDE, you can very easily create a new window in a TopComponent that interrogates Yahoo News via a web service. Assuming that's been set up, let's drill from one news item into another news item. Rather arbitrarily, we'll assume that the children of the current node should be determined by the last word in the...
