If you read the NetBeans Nodes, Explorer Manager, and Component Palette Tutorial, you will learn several cool things—how to create a tree view, how to add cut/copy/delete functionality, how to enable drag/dropping of children between nodes, how easy it is to change explorer views and, finally... how to turn your node into a palette item in a Component Palette. All in the space of one tutorial which is so hot off the presses that your eyes will burn while reading it. Feedback...

This is something I discovered by accident recently. It works in all editors everywhere (i.e., also outside NetBeans IDE and also in, for example, browsers). But, if you don't know about it, it is really helpful (once you do know about it). If you do know about it, it is really "duh". So, this is written for those who don't know about it (so please don't leave comments that basically say "duh"). In the Source Editor in the IDE, you often need to select a single line, for...

I've got a bit further with the WebFrameworkProvider wizard that I talked about yesterday. Now, after creating a module project and adding a dependency on the Web APIs, you can go to the New File wizard, choose the WebFrameworkProvider template, and you will get this panel: There's a handy list of framework names (totally random, from yesterday's blog entry) predefined for you. But it is a combobox, so you can add your own framework name. Also specify the name of a class and...

In Rich Unger's blog, I found this list of web frameworks, although I'm sure there are hundreds more (excluding the thousands of inhouse frameworks that companies seem to inflict upon themselves): Beehive Cocooon Echo EJB Hibernate iBatis JDO JSF Keel Maverick SiteMesh Spring Struts Tapestry Tiles Velocity WebWork WebObjects Wicket Here's the fastest way of implementing support in the IDE for any/all of the above: Download and install this brand new module (created and...

This morning when I got to work, a package with 3 copies of the above German-language Javamagazin was waiting for me! Yay. (Thanks Jens, I think.) Last month, the cover theme of the Javamagazin was NetBeans (click here) and this time... NetBeans is highlighted again! The article focuses on plug-in development and rich-client platform development. It is written by Jens Trapp, who I interviewed sometime ago here. The article has some cool screenshots in the module...

NetBeans engineer Stepan Herold has created and open sourced JOnbAS, the JOnAS plug-in for NetBeans! Hurray. The features are as follows: Starting and stopping the server Java and JSP debugging Generating the default server specific deployment descriptors Deploying, undeploying the Web, EJB and EAR modules Browsing the deployed WAR, EJB and EAR modules To get started with JOnbAS, go here: http://jonbas.sourceforge.net/ Note that this is the first alpha build of this plug-in and...

Ever since blogging about Jazzy, the Java open source spell checker, yesterday, I've been totally engrossed in working on an HTML spell checker. I've been especially focused on extending the Output window, because that way the hyperlinks from wrongly spelled words are provided by the NetBeans Platform, instead of by me. The best way of learning about this NetBeans API feature is to read the interview with Jens Trapp and to then download his open sourced HTML Tidy integration...

Something I've missed in NetBeans is a spell checker for HTML files. The one by Jan Lahoda on nbextras.org is for Java files only (although the description there says it should be easy to extend it). Mine is specifically for HTML files (although it too is very easy to extend for any document). It is based on Jazzy, the Java open source spell checker. My first experiment with Jazzy just reused the code found herewithin the context of a JEditorPane in a simple Java...

The 2nd day of JavaZone in Oslo was really very interesting. First thing in the morning, at 9.00 a.m., Romain Guy did his presentation on filthy rich clients. As a result, I'm definitely going to have a look at the open source TimingFramework. Next up was Heinz Kabutz, who writes the Java Specialists' Newsletter. He did an excellent presentation on dynamic proxies in Java. After that, I took a break, the only break I took throughout the day, because there were so...
