Re: Using HSSF & getting error

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?
