Let's say I have a file called test.txt within the package "com.test.io" within my jar.

How would I go about writing a class which retrieves this text file and then copies the contents to a new file on the file system?

Assuming said jar is on your classpath: 

URL url = getClassLoader().getResource("com/test/io/test.txt"); FileOutputStream output = new FileOutputStream("test.txt"); InputStream input = url.openStream(); byte [] buffer = new byte[4096]; int bytesRead = input.read(buffer); while (bytesRead != -1) { output.write(buffer, 0, bytesRead); bytesRead = input.read(buffer); } output.close(); input.close();

you could just use .getResourceAsStream() </nitpick> :)
thanks for that information. I was thinking of doing something like that however I thought I may have missed something simpler, kind of like using something from apache commons io fileutils (or something similar)
Furthermore, is there any significance to the 4096?
