Maven

As you are probably using Wicket, it is not entirely impossible that you are using maven already. In that case, just add this to your pom.xml:

 <dependency>
   <groupId>org.codesmell</groupId>
   <artifactId>org.codesmell.wicket.tagcloud</artifactId>
   <version>[0,)</version
 </dependency>

Be sure to configure your Maven or your corporate Repository or Repository-Proxy to use this URL:

http://www.codesmell.org/maven/

Download

If you want to use this without maven, just download the current jar here.
