Did you really set the "classpath" environment variable?  It should be
"CLASSPATH"; environment variables are case-sensitive.

But the real problem is that you're using the wrong continuation
character for your RPG literals.  The - continuation means "start at the
first available position"; the + continuation means "start at the first
non-blank".  So you're try to use class 
    'org.apache.poi.hssf.usermodel.       HSSFWorkbook'

(The error message should have shown what class it couldn't find.)

By the way, I find it useful to define a named constant, like
WorkbookClass, with a long class name.  Then you only have to code the
long form once.  Also, you don't need to code the CLASS keyword for a
constructor; the class of the return value is the same as the class of
the constructor.
