Re: Class Not Found -- MIDRANGE-L

That's the answer, I was certain that I tried logging off and back on again after I bombed it the first time, but I must still have had an environment error in there and fixed it after I signed off and signed back on.

Mark,

It's important when calling Java from RPG that the CLASSPATH be set
before any Java is used in the job. It only reads this environment
variable once -- and that's done the first time any Java is used for the
entire job.

So if you are running this interactively sign off and back on again.
Then set the CLASSPATH, then try the program again so that you know it's
the first time it's used in the job.

Other than that, I don't see why your example wouldn't work.

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

Here's my classpath (i know it is short, but the class in question should be found at least)

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 the class I am looking for right now).

Here is the error:

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.
