Scott:

It runs for about 20 minutes - would love for it to run quicker but don't
have any ideas on how to achieve that.

Your tip on looking at the QIBM_RPG_JAVA_PROPERTIES variable led me to our
CL that is called before we build the spread sheets. I found that it was
changed to be pointing to the 64bit of jdk60 - It used to be jdk50/32bit

So I changed it to the following & now my program runs.

ADDENVVAR ENVVAR(JAVA_HOME) +
VALUE('/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit') +
REPLACE(*YES)

Is there any reason to go back to jdk50 or can I leave it at jdk60?

I haven't experienced this problem, myself, as I don't create
spreadsheets that large with HSSF. (It must take forever to run!)

But, I do know that it's possible to tweak the amount of memory that
Java allows programs to use in the QIBM_RPG_JAVA_PROPERTIES variable.
Maybe worth try?

Have been using Scott Klements HSSF programs to create some Excel spread
sheets & has been working great. Today I add 2 new columns to be put on
the spread sheet & when I run the job it blows up with
"java.lang.OutOfMemoryError" The spread sheet has 25 columns & contains
37249 rows. What do I need to do so that I can continue to run this?

Thanks!!
