is it possible to decompile a running applet to get the source code back?

What do you mean? Reverse engineer Byte code? If that's
the case I have read some where that it is possible to
reverse engineer byte cod. You may get the method signatures
of any class the applet uses by running javap against the
Class file.

javap SomeClass.class;

In any case why are you trying to reverse engineer someone's
byte code? Nothing malicious I hope.

You need the applet's class files (or jar files) and a decompiler (DJ Java Decompiler for example).

If I am not wrong understanding your query, I agree with Matthias that you need a decompiler to do the job. There are Java decompilers available which will decompile a Java applet into compilable Java source code. Since Java uses no preprocessors and has a very specific byte code format, the decompilers have surprisingly good output. Here are a few links for further info.
