A simple TFTP server implementation for Java. This project is a fork of the TFTPServer project by Dan Armbrust. This server was published (like this project) under an Apache 2.0 license. Since Dan's implementation is no easy to find, I have added his work as TFTPServer.original in this distribution.
The difference between the implementation by Dan and this project is that the file system is factored out. If you provide a class that implements IFileNameMapper, you can controll which kind of stream shall be returned to the sender.
I basically kept the original behaviour implemented by Dan Armbruster by adding a DefaultFileNameMapper that emulates his implementation.
The project contains a class named ProxyFileMapper. This class can be used to redirect TFTP request to a http server.
You need some code like this to use the ProxyFileMapper:
Logger.getRootLogger().addAppender(new ConsoleAppender(new PatternLayout()));
ProxyFileMapper proxyFileMapper = new ProxyFileMapper("http://google.com/");
TFTPBaseServer baseServer = new TFTPBaseServer(proxyFileMapper, 8089);
Now all TFTP requests for a file named "x/y/z" will be mapped to http://google.com/x/y/z. (Please don't use google.com in your production code. This address was only used as a neutral address for demonstration purposes)
