Error running java program from a CL using QSHELL

I have a CL program that calls a java program using QSHELL

It works fine on our Power8 running 7.1

I move the CL program and the java files to another machine (also
running 7.1)

When I try to execute the CL on the 2nd machine I get the error shown
below:



I am not a java guru but I believe (from reading almost the complete
internet) that it has to do with not being able to find a java class

My first question is

1. Does this error say it can't find com.gnostice.pdfone
or does it mean com.gnostice.pdfone encountered an error trying to
find java.net.URLClassLoader.findClass

Or does it mean something else?



2. I am not 100% sure which (if any) java directories/jars need
to be in the classpath or does the IBM I take care of the java classes
for me?
There are these two values in all of our CLASSPATHS:
/QIBM/ProdData/OS400/jt400/lib/jt400Native.jar: /QIBM/Prodata/JAVA
(I believe because all of our java programs were created by copying an
existing one)



The first text line of the error does not look right (the
pdfone.PDFOne part) or is that just the way that java formats its
messages?:
java.lang.NoClassDefFoundError: com.gnostice.pdfone.PDFOne






Both machines are running IBM I 7.1 and java 1.7
