Re: Upgrading from V5R4 to 7.1. Java Classic to IT4J

Hi Mark,

Believe me, I'm not trying to get it to work with the 32-bit JVM, I though it was the only option I had.
If I can still point the software at the 64-Bit JVM GREAT!! I will sleep better tonight.

I will look it up and point the software back at the 64-Bit machine. I'll let you know how it go's.

Regards,
Mark.

Mark:

Even with IT4J, IBM still supports both a 64-bit JVM and a 32-bit JVM
...  if this application was all "working fine" with the "classic"
64-bit JVM, why are you are trying to make it work in a 32-bit JVM?

Hi Evan,

If you think it could be a JVM issue who would it get reported to. The JAVA code being used is Apache and IT4J is IBM.

Mark.

I'm with Luis on this - it looks more like a JVM issue.

I don't see how recompiling will help other than to provide one more reason
for the java guys to look at it.

Hi Luis,

I am going to take all source from the V5R4 machine and recompile on the
7.1 machine. Would that possibly solve the problem?
I am not a JAVA programmer.

Regards,
Mark.

Mark,

IIRC, Is it possible that your old program(s) need the 64-bit version of
Java and right now (under the new release) they are pointing to the "new"
32-bit version?

Is there a good document on upgrading from V5R4 to 7.1 where RPG calls
JAVA programs?

I have programs created at V5R4 being installed on a 7.1. Most work
perfectly but there are a few issues
such as '"java.lang.StringIndexOutOfBoundsException' happening.

Do the programs need to be recompiled directly on the 7.1 machine?
Do I need to recompile all programs with teraspace enabled?

The setup has been changed to point at the new 'IBM Technology for Java'
JVM rather than the Classic JVM.

Any help greatly appreciated.

Regards,
Mark.
