Re: loading plain files

Another thing you can do is to just try Configuration.getTemplate(),  
and if you get a FileNotFoundException, fall back to retrieving a  
classpath resource yourself.
Or, if you're worried of having an exception as part of your normal  
control flow, you can also try first looking up the classpath resource  
with Class.getResource() and if it returns null, only then fall back  
to FreeMarker.

Another advantage of this approach instead of having FreeMarker serve  
static content is that you can return Last-Modified headers in HTTP  
responses (i.e. with the timestamp of the JAR file itself), and  
handling If-Modified-Since request headers, or even returning Expires  
headers with some sane values. That way you can take advantage of HTTP  
clients' caches (if they have any, i.e. if they're regular web  
browsers, then they obviously do) and reduce traffic on your app.
