One of the absolute highlights of my trip to the Grails eXchange last week was... hanging out with Scott Hickey, the main developer of the Groovy plugin for Eclipse. Here's a pic of us in a bar after the first day at the conference; you can't see all the other people around, nor the Black Sheep beer (because I think we were still waiting for it) and the reason that the pic is so grainy is that I couldn't get my flash to work, which was because I had my camera set to 'movie'...

As of today, the JFugue Music NotePad is running on JFugue 3.2. It continues to be based on NetBeans IDE 5.5 (or NetBeans IDE 5.5.1), however, so don't make the mistake of trying to open the project in some build/milestone/beta release of NetBeans IDE 6.0! Once you have it running (which should be possible without a single hitch, after checking out nbjfuguesupport from dev.java.net), you should be able to compose music, with results similar to this: The latest enhancements...

Vadiraj, and his team in Bangalore, have been working on the openInstaller, which is a framework for creating cross-platform installers. The NetBeans Application Installer Generator can be seen as the reference implementation of the openInstaller project. You can use it to create an installer for your NetBeans Platform applications, such as this one for the Feed Reader, which is one of the samples bundled with NetBeans IDE: Check out the the Wink screencast, which shows how...

Second Life is featuring the Rich Client Programming book: Thanks for the info and pic, Vadiraj! An interview with him about his amazing installer generator is coming soon, so watch this space!

I put a breakpoint in the Java class I showed yesterday and am now able to step through the Groovy script, with the Local Variables window showing the current state of my Groovy variables: Funnily enough, Scott Hickey, the main guy behind the Eclipse plugin for Grails and Groovy, is the one who worked with me in (a) coming up with the procedure I outlined yesterday and (b) thinking up the possibility of debugging Groovy, in the way demonstrated above! The Grails eXchange is...

Something I learned today at the Grails eXchange here in London. Without any plugins at all, you can already call Groovy scripts from Java code in NetBeans IDE, as outlined below.Start by creating a small script called "HelloWorld.groovy", using the "Empty File" template to create the file, with this content: package demojavaapplicationclass HelloWorld { static void main(args) { println "Hello from Groovy!" }} Now, we will set the project up so that the above...

A new NetBeans Platform developer wrote to the docs feedback alias, in response to the Recognizing a File Type Tutorial, the following words: "How do we actually change the contents of the new .mf file? what if I don't want it to be in text format? what if I want it to open up a another project X (with its own topcomponent, palette and graphscene) when the user creates a new file type?" Well, the answer is found in an earlier blog entry entitled Elvis, Einstein, and Advanced...

A quick overview of some Grails support that's been cooking in the background. First, a new Grails wizard, at the end of which the create-app script is run by the IDE: On completion of the wizard, you have a Grails project source structure, with Groovy files being recognized as such: Then there is a right-click contextual menu item on the project, for deploying the application, with the results being written to the Output window: And then 2 minutes after starting the wizard,...

The simplest implementation of the Task List API is even semi-useful. It finds all the files in a project, either the main project or all opened projects, and puts them in the Task List, as shown here: You then get all the Task List features for free, such as that when you click on a row in the Task List, the related file opens in the Source Editor. Other features, such as sorting, and other organizing functionality, is also available. All for adding a handful of lines of...
