Yesterday, I came across yet another NetBeans Platform application in the defense sector. Raytheon's Virtual Control "is a flexible enterprise management and control system that has been designed to support a wide range of distributed system needs. Its robust capabilities are being applied across the LVC domains to support some of the most critical development programs in the Department of Defense (DoD)". That, all on its own, is a nice endorsement of the NetBeans Platform,...

Next in the JFugue Music NotePad, I am working on creating a "cut action", which means integrating with the NetBeans Platform cut action. As you can see below, when (and only when) one or more notes are selected, the cut action (look in the toolbar) becomes enabled: How to do this yourself? Inside the TopComponent, I have these two lines of code, which links the "cut-to-clipboard" action to an action registered in the layer: final ActionMap actionMap = getActionMap();actionMap...

Thanks to the injection of the domain object into actions (an approach discussed in this blog yesterday), it is now possible to play multiple scores simultaneously in the JFugue Music NotePad (see the menu items 'Melody' and 'Harmony' on the root node in the brand new viewer component below): Pretty cool. Now, either all the sheets are played consecutively (melody) or simultaneously (harmony). (Plus, as before, they can be played individually too.) And all thanks to the...

The real message of the article "How to Make the NetBeans Platform Sensitive to Customers", which I recently wrote on NetBeans Zone, is that actions in applications on the NetBeans Platform can be sensitive to their business objects (also known as model objects). In the case of that article, the business object was "Customer", while in NetBeans IDE the business objects are "FileObject", "DataObject", "Node", among others. One of these is org.netbeans.api.debugger.jpda.ObjectVa...

Have you written a university/college thesis that discusses the NetBeans Platform in some way? To assist others doing the same thing, we're collecting as many as we can get hold of and posting them here: http://edu.netbeans.org/thesis.html Drop me a line / leave a comment at the end of this blog entry if you'd like yours to be included there too! The latest one is by Jan Poživil, who wrote a Masters thesis on top of the NetBeans Platform in May 2009, at the Faculty...

The java.net featured project is https://uamath.dev.java.net/, which is a Set of Calculators for the New Force Material Equivalency and Compression Decompression Model of the Universe. Don't know what that means exactly, but when I run the app (which is a NetBeans project), I see a central control frame, from which the calculators can be opened: Here's how the same application looks on the NetBeans Platform, which means that you can see many calculators simultaneously,...

It's possible to extend the Hippo CMS, via Maven-based Wicket-style applications, as can be seen here: The Java-side of the Wicket label seen above has this interesting Wicket-oriented code: add(new Label("label", new LoadableDetachableModel() { private static final long serialVersionUID = 1L; @Override protected Object load() { UserSession session = (UserSession) org.apache.wicket.Session.get(); String name = session.getJcrSession().getUserID(); ...

As a free and open-source Wicket-based Maven-built content-management system with a very cool name, Hippo deserves praise. Getting started developing a website on Hippo with NetBeans IDE is trivial. Start with the Maven Project archetype: Use the Generate Project Setup page to create the project, with these values: Repository: http://repository.hippocms.org/maven2 GroupId: org.onehippo.ecm.archetypes ArtifactId: website Version: 1.01.00 I.e., in the IDE, use the dialog you get...

In answer to my own question, I managed to get the dependencies needed for Gunnar's sample running in Equinox down to 26 OSGi bundles (from 1000+ a few days ago!): com.ibm.icu_4.0.1.v20090822.jarorg.eclipse.core.boot_3.1.100.v20080218.jarorg.eclipse.core.commands_3.5.0.I20090525-2000.jarorg.eclipse.core.contenttype_3.4.1.R35x_v20090826-0451.jarorg.eclipse.core.expressions_3.4.101.R35x_v20100209.jarorg.eclipse.core.filebuffers_3.5.0.v20090526-2000.jarorg.eclipse.core.filesyste...
