Getting a reference to the current executed jar

When bundling my whole application into a executable jar , i can get images but not sound files... i use the ClassLoader.getSystemResource() for most items.. but ".wav" and possible overs wont load. These wavs are in the executed jar. What is a better way i could get a reference to them, and also to the executed jar file itself (for manual extraction).
