The JTidyServlet project (mentioned in various answers) appears to be more or less defunct -- no browsable source, no downloads linked from the SourceForge project page apart from the main JTidy download (which doesn't include the servlet or filter), no Maven artifacts in any repositories I can find. Can anyone recommend a more up-to-date alternative?
Looks like there's some source code here; https://github.com/vnc-biz/zcs-lib-jtidy/
