Who knows the future of JWebPane. Time to look for alternatives, in my humble opinion. Aljoscha Rittner, who is giving a NetBeans Platform Certified Training together with me in Bielefeld, Germany, recently figured out how to integrate DJ Native Swing into the NetBeans Platform. (He's not the first, look at the screenshot here and then at the comments at the end of that article.) Now I know how to do it too, since he transferred all his knowledge to me: The menubar within the...

As requested by Joonas and others on the Vaadin team, it's now possible to access the list of Vaadin versions, and choose one, which will then be downloaded, when creating Vaadin-based web applications in the IDE: When you click the "Download" button, you see info parsed from this handy file that the Vaadin team made available for these purposes, as shown below: I checked in an initial version of the above functionality into the Vaadin repo on Kenai. Some fixing and testing...

A second session on the NetBeans Platform was held at SkillsMatter last night (here's a report on the first). Below you see Jaroslav Tulach and Toni Epple in action: During the "No Slides, Just Code" demo, they created a small Twitter Client application on the NetBeans Platform, illustrating many of the main NetBeans Platform concepts along the way. It was great to meet several developers from the NetBeans Platform community, such as Edvin Syse (read about why he moved from...

Final days of my vacation (haven't left Crete yet) and I'm beginning to catch up on things. The best thing I've come across in the past weeks is this link: http://layerxml.wordpress.com/ It is by a NetBeans Platform developer in Sweden, Nicklas Löf from Artificial Solutions, who have a few NetBeans Platform applications of their own (search for them here), such as this one, an inventory management system: Nicklas' new blog currently includes entries on Lookup, Nodes, and...

One way to measure the success of an open source project is to look at the kind and quality of contributions received from the project's community. In this sense, the NetBeans Platform has recently been very successful. First, James Reid recently contributed a tutorial dealing with creating a custom editor on the NetBeans Platform. Using an ANTLR Lexer For Syntax Coloring Tutorial Result: Then, today, Andreas Stefik extended that tutorial to incorporate a custom debugger for...

Independent contractors from South West Gas, as well as Vehicle Control Technologies (contractor to the US navy), among others, attended the latest & greatest NetBeans RCP training here, in San Francisco. Group pic: Next training at Marakana, the very well organized training organization who set up the above sessions, will be in San Francisco from March 7 to 9, 2011. Please feel very free to sign up for that course already. Based on the feedback received, the attendees were...

Let's say you're creating a customer application where you have different toolbar buttons and menu items that need to be enabled depending on various states of the underlying customer object. For example, let's say you're analyzing resellers of a product. You're creating an application that includes handling responses to the state of what a reseller has done with the product you've sold them. So, one state may be "the reseller has paid", another state may be "the reseller has...

Let's say you need a (1) menu item in the right-click popup menu of a node and a (2) toolbar button in the main toolbar to be enabled/disabled based on the current state of an object. Below is a case in point. We have a vehicle console that has an "Install Vehicle" action. That action applies to the underlying "Vehicle" object, which is wrapped in a BeanNode, "VehicleNode". The "Vehicle" object has two booleans, among other things. The booleans, "standby" and "available",...
