Like I said, I have not looked at JZOS for the past 2 years, but I was not able to run the supplied sample classes with 64 bit java. I will re-download them and try again.

The JZOS toolkit class library (and native code) in included in the 64-bit SDKs. I don't know what problem that you were having, but it sounds like a CLASSPATH problem with using the sample classes, which are not included in the SDK unless you download them.
