staticwiki is a configurable java wiki renderer. The rendering is done in several passes to allow a lot of versatility.
One of the features (hence the name) is that it can be combined with maven to generate a static site using wiki context.
However the renderer itself could easily be used in on the fly wiki rendering. In fact the rendering should be pretty fast as it does not use regex matching.
Though the markup could be configured, the default wiki dialect which is used is similar to the markup used in Confluence.
