You need

* To know what a WAR file is and how to use it.
* A Servlet 2.2 -compliant web server. For example, Tomcat 3.2 or above.
* A server to run your Wiki on. It does not have to be a very big server: is being run on a 266 MHz Pentium II with 192 Mbytes of memory.
* Some patience (the setup is not as easy as I would like it to be)
* If you want RCS-based version history, you also need RCS. Most UNIX systems should have this pre-installed, for Windows you'll need to find it from somewhere. However, you can also use an internal VersioningFileProvider, which does not require RCS.
* If you want to use the mailing capabilities in log4j, you need JavaMail and the Java Activation Framework libraries.
