RE: HSSFR4, 7.2 Upgrade and Start JVM.

John,

Which Java JVM version were you running on V6R1?
6 is minimum on V7R2.
5 still available on V7R1.

Make sure you have the latest CUM PTF and Java group PTF.

I'm running 7.2, and not having problems like this...

We upgraded from 6.1 to 7.2 Saturday Aug 15th.
This week a spreadsheet program i wrote stopped working so I went back
to Scott Klements example programs in the poi36 library and get the
same thing.
It crashes hssfr4 on the start_jvm line.
here is the overview of the joblog messages -

The error occurs in the hssf_get_jni_env() procedure (below) on the
start_jvm() line.

Is there some change made in 7.2 that needs to be allowed for / some
adjustment that needs to be made in order for hssfr4 to keep working?

-Any- ideas are greatly appreciated.


Another clue is if i do a wrkjvmjob, after trying to run the
spreadsheet pgm, no entries show up under my user profile.
(leading me to believe the issue is something to do with starting the
jvm)


Thanks,

John
