i just downloaded the latest samples and see that many were recompiled in
2016/2017.
the ones I had downloaded back on June 1, 2017 were compiled back in 2012/2013.
so it looks like they have changed since I last used them and may have been
fixed to work with 64 bit java.

Subject: Re: Do I need to copy a mainframe flat file to OMVS, before I access
the data from a JAVA program? - JZOS question
The ZipDatasets sample program works fine with the 64-bit SDK.
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.
