Some pretty bad news—Sandip Chitale, one of the key players in the popularization of the NetBeans Platform, has left Sun. Although he never worked in any official capacity in relation to the NetBeans Platform, his contributions were really significant: His blog is a rich mine for anyone interested in the NetBeans Platform. Unlike virtually everyone else, he didn't only write about the plugins he created, but he provided LOTS of code that others could learn from. Over the...

Here, based on an existing example, is how to migrate from "TreeTableView" to the new NetBeans Platform 6.5 "OutlineView":Install the Marilyn TreeTableView Sample. Create the sample, i.e., choose "Samples | Java | Marilyn" in the New Project wizard and complete the steps in the wizard. Add the following JARs from "platform9" folder in the NetBeans installation directory to the app's classpath: org-openide-actions.jar, org-openide-awt.jar, org-openide-dialogs.jar, org-openide-ex...

In the coming weeks, a free on-line NetBeans Platform Training Course will be made available. It will be based on Tim's excellent "PovRay" series, which is currently severely out of date and has been causing a lot of questions for a while, even though those who work their way through the problems tend to end up with the result they were looking for in the first place. In that context, his tutorial will be removed from the web because it will be part of the course. The most...

The Plugin Portal now provides a new sample demonstrating the new (NetBeans Platform 6.5) Explorer View called "OutlineView", which is a simpler and more powerful alternative to the NetBeans TreeTableView: http://plugins.netbeans.org/PluginPortal/faces/PluginDetailPage.jsp?pluginid=12094 After downloading and installing the plugin, you will find the sample here: After completing the wizard, you will have these sources: Run the sample module and you will have a TopComponent with...

Without question, Wicket in Action, soon to be released by Manning, is the be-all and end-all when it comes to Wicket. How could it be otherwise, since it is written by two of its core members and key players, Martijn Dashorst and Eelco Hillenius? I've been lucky enough to have been given a chance to examine it prior to its release... and here are my impressions. First of all, if you're new to Wicket look no further. "Wicket in Action" provides everything you need. In...

Casper Bang asked a great question at the end of my previous blog entry about the new code completion tutorial: We have a desire in our team to get code completion for JPA queries. However, JPA is an embedded DSL inside string annotations. Does the approach described in the tutorial also apply if one wanted to "sub-tokenize" and provide completion inside a String token of a x-java MIME type? The answer is, of course, "Yes!" To set up a scenario, I recreated my code completion...

When you press Ctrl-Space in the IDE, a code completion box pops up with words that you can use to complete the word under the curser. Here's a new tutorial that explains how you can create code completion functionality for your own MIME types or for one of the existing ones: NetBeans Code Completion Tutorial The tutorial replaces an older one. It's much better because it focuses specifically on code completion, not on extraneous stuff like web service clients and Options...

Here's the next podcast, featuring a lengthy interview with Python's Ted Leung, a short chat with NetBeans User Researcher Jakub Franc, and all the regular bits: Jaroslav Tulach's API Design tip, the project of the podcast, the plugin of the podcast and ... the puzzler!

In the last few days, I've blogged about Groovy scripts that generate application source structures. As examples, I used a Groovy script that generates a skeleton NetBeans Platform application and a Groovy script that generates a skeleton NetBeans module. At this point, it should be possible for me to put the scripts into the Grails "scripts" folder, create a GANT script that calls the Groovy scripts, and then run this command from the command line: grails netbeans Then a...
