To disassemble an entire  jar file as a disassembled dex use the following:

dx –dex –dump-to=abc –locals=full –positions=lines com.saville.android.debug.jar

Click here to see the output.

Here is an example of using dx, the android jvm-byte-code to dex converter to disassemble a method in a class. The input is a “.jar” file of my debug class and I’m dumping the print method of class Log:
