How to display source code in browser?

[Migrated From Jforum.net]

I want to show java, xml or whatever; source code in my jsp pages to user, means in the browser. I have seen in many blogs and jForum that whenever we make use of code tags the code taking a very good formatting and style. Is there any open source libraries available to achieve this? How it is done in jForum? Please help

Waiting for a positive response.

Well I got the answer. Have to use Google syntax highlighter.
