Try loading a class or properties file as a resource, then look at the path for the resource. That should get you the information you need. I think this code will work (substituting the class names with classes in your app): Class class1 = ClassInApp.class; URL url = class1.getResource("ClassInApp.class"); String s = url.toString(); The string 's' should contain the full path to the class file, which contains the tmp/deploy directory.
