JHighlight is an embeddable pure Java syntax highlighting library that supports Java, HTML, XHTML, XML and LZX languages and outputs to XHTML. It also supports RIFE templates tags and highlights them clearly so that you can easily identify the difference between your RIFE markup and the actual marked up source.

The newest version!
