Class Not Found -- JAVA400-L

I am having trouble with Scott Klements POI examples, specifically it can't find the HSSFWorkbook class

here's my classpath

Display Environment Var (*JOB)

Name . . . . . . . . . : CLASSPATH

Value . . . . . . . . . : '/java/poi-3.11/poi-3.11-20141221.jar'

(I know there are a lot of things missing, but this one jar should contain what I am looking for right now).

Here is the error:

Class not found, but this is a partial listing of /java/poi-3.11/poi-3.11-20141221.jar:

The class is obviously there.

I did the following in QShell, this is a partial list of environment variables
OSTYPE=os400
MACHTYPE=powerpc-ibm-os400
CLASSPATH=/java/poi-3.11/poi-3.11-20141221.jar <<<< This is the whole classpath for this session
TERMINAL_TYPE=5250
PATH=/usr/bin:.:/QOpenSys/usr/bin

Yet I get the following error:
$

javap -s org.apache.poi.hssf.usermodel.HSSFWorkbook

ERROR:Could not find org.apache.poi.hssf.usermodel.HSSFWorkbook

and here is what that directory looks like:
$

cd /java/poi-3.11

ls

poi-3.11-20141221.jar
$

How do I coerce java to find the class? In qshell and RPG.
