ClickIDE requires Eclipse 3.2.x and WTP 1.5.x. The easiest way to use ClickIDE is introducing WTP using Callisto.
After WTP installed, get ClickIDE from the SF.net download page. Unzip clickide-x.x.x.zip and put 2 folders (plugins/ and features/) into your ECLIPSE_HOME.
Create "Dynamic Web Project" in the J2EE perspective and select "Click" as Project Facet. The project creation wizard will add Click JARs, web.xml and template of click.xml into your project.
ClickIDE provides the visual editor for the Click configuration file (click.xml). It has some tabs. You can edit click.xml using this editor easily.
In the "Source" tab of the configuration file editor, you can edit click.xml directly and you can jump to the source code of the page class and the page template by CTRL+CLICK. ClickIDE also provides the validation for click.xml. Error markers are displayed in the editor and "Problems" view.
You can create the page class and the page template file using the page creation wizard. In the wizard, you can choose template for the page class and the html file. These template can be configured at the preference dialog ("Window" > "Preferences" > "Click").
ClickIDE also provides the Velocity template editor. This editor provides code-completion, highlighting and validation as velocity syntax. You can also configure highlighting colors in the preference dialog.
In the JDT's Java editor and the Velocity template editor, you can switch between the page class and the html file by CTRL+ALT+S.
Click documentation is integrated with the Eclipse help system.
