title: Anti-XSS java libraries
body: <p>I'm looking for a java library that can provide protection against <a href="http://en.wikipedia.org/wiki/Cross-site_scripting" rel="noreferrer">XSS attacks</a>. I'm writing a server, and would like to validate my user's input doesn't contain malicious javascript.</p>
  
  <p>Which library would you recommend?</p>
