BTW, since you are new to JIDE, you probably don't know the webstart demo and evaluation package. The JCL library (the jar itself) is available on java.net but the demo for it is in the eval package which you can download from
http://www.jidesoft.com/evaluation/. We can't put it on java.net as the demo framework itself depends on some other JIDE components. Once you get the eval package, unzip it and open the examples project in NetBeans, you can see a lot of demos. There are demos for AutoCompletion and IntelliHints respectively. You can look at the source code of the demo to figure out how to use these two features. Just so you know, you need to write code for it. It is just a couple of lines of simple code but you can't enable the features by drag-n-drop using NetBeans GUI builder.
