Adding .gitignore to ignore files created by Eclipse

Hi, I want to help improving jawr. We are Java developers for a popular site in Germany http://www.kicktipp.de/ and had so far used a home grown tool written by us. Now we switched to jawr. I am just starting setting up the development environment. I always try to commit small steps, this is one little tiny baby step ;-) 
kind regards 
Janning
