The general solution is to setup your Tomcat behind an Apache server. * mod_headers* works well on just Apache, so you can use a filter there with * mod_headers* to add the gzip headers. This way the browser knows that this js file is gz encoded.
A tip, I noticed if I just name files like script.js.gz, some firewalls tried to convert them to gzip MIME from JS (because they saw the .gz), breaking the app. So, I just made up my own ending and called it .jsz. Now I can easily just *.jsz to applied mod_headers too. You can also create your own filter and do this all in Tomcat (like this example <http://stackoverflow.com/questions/2876250/tomcat-cache-control>), but remember this adds overhead and complexity, so why not just let Apache do it for you?
