java library to prepare user comments for displaying on the web?

Do you know of any good lightweight library in java to make good and safe HTML representation of user input? That's very generic task, I think. Consider: user leaves a 开发者_如何学JAVAcomment in the blog - my task is to convert user comment into safe & nice HTML content.

Use the jsoup HTML Cleaner with a configuration specified by a Whitelist.

String unsafe = 
  "<p><a href='http://example.com/' onclick='stealCookies()'>Link</a></p>";
String safe = Jsoup.clean(unsafe, Whitelist.basic());
// now: <p><a href="http://example.com/" rel="nofollow">Link</a></p>

Excerpt from the Jsoup Cookbook.

HTML Parser is a Java library used to parse HTML in either a linear or nested fashion. Primarily used for transformation or extraction, it features filters, visitors, custom tags and easy to use JavaBeans.
