I'm thinking on adding Markdown to a Java project with using:
Q1. What javascript library can I use for the client side? I'm thinking on using Cletus' 
port of MarkDownSharp for the backend.
Q2. What strategy should I follow to add JMD to my project? My code it's a Maven project already. If JMD were available for maven I would just create a dependency on that, but it is not. So, should I merge it with my code base?
Thanks in advance.

ShowDown, WMD (still not open sourced) and markItUp! seem to be the most famous options, the later being maybe the closest to what you're looking for.

Hmm... what? I'm not sure I understood the question, but I'll try. If JMD is available in a known repository, just add a dependency on it. If it isn't I would get the sources and add them to my codebase as a module (not a bid deal, there are less than 10 classes) and sync them from time to time.
