Bonus tip: you can always find a recent version of the Quercus WAR file at http://www.caucho.com/download/quercus-4.0.x.war, replacing 'x' with the latest version, e.g. http://www.caucho.com/download/quercus-4.0.28.war. You can find the latest version number by looking at Caucho Resin's version number on the website's download page. I figured this out once by guessing URLs to download the latest version. The Quercus website is not updated frequently enough to keep up with newer releases, but the files are actually there.
