I just uploaded my Java webserver including source to the charlotte project page. Here is a little excerpt
Charlotte is a really simple Web Sever developed in Java. Its feature set consists of serving static files from disk, and reporting errors like ”file not found”
But appearances can be deceiving, because Charlotte can also be described as a simple http application using a Java HTTP Framework called Lone. By that definition, Charlotte is reduced to a simple demonstration of what can be accomplished with Lone.
Just thought you'd like to know.
