There is a lot of discussion around how to develop portlets using Wicket.
If you download a Wicket distribution package, there is the "Wicket Examples" webapplication WAR enclosed.
This package is not only a webapplication, but can also be deployed as a (collection of) portlets.
Here is how to run the examples as portlets:
- Download Wicket (e.g. apache-wicket-1.4.3.zip)
- Unzip the package
- The Wicket Examples package enclosed is e.g. "wicket-examples-1.4.3.war"
