Is not very portable to specify the absolute path of notepad. If you pass the program to your friend it might not run!
I usually specify only the document.txt and the shell exe file (in windows xp cmd.exe), then the operating system think how to open the file. You can setting the operating system to open all the .txt file with notepad. It is very easy.
The your .txt document in your classpath, so is relative and not absolute.
Here the code:
String cmd = "cmd.exe /c start ";
               String file = "mydocuemnt/manual.txt";
              try {
                    Runtime.getRuntime().exec(cmd + (ClassLoader.getSystemResource(file)).toString());
               } catch (IOException ee) {
                    JOptionPane.showMessageDialog(null, "The document dosn't exist!",
                              "Document not finded!", JOptionPane.ERROR_MESSAGE);
                    ee.printStackTrace();
               } bye
