Instead of hardcoded text just read the file content as bytes. The rest is the same.
I'm sure you can google out plenty of examples like this one:

 Path path = Paths.get("C:/temp/test.xml");
 byte[] data = Files.readAllBytes(path);
Enter fullscreen mode Exit fullscreen mode

Then :

exchange.getResponseHeaders().put("Content-Type", "text/xml");
exchange.sendResponseHeaders(200, data.length);
OutputStream output = exchange.getResponseBody();
 output.write(data);
 output.flush();
 exchange.close();
Enter fullscreen mode Exit fullscreen mode

Haven't checked it compiles but give it a try.
