Use the getResourceAsString method of Class to obtain the file as an InputStream, then use a FileOutputStream to create a new file, and use a loop reading and writing byte by byte from the above InputStream to the FileOutputStream until the end of the InputStream is reached, then close both Streams, and there you are.
The IO tutorial covering ByteStreams contains the exact loop you need.
And read the API (or Google) for the usage of the getResourceAsStream method.
