Re: Improving Excel generation performance through calling Java

Be very careful doing that. It's not advised to put classes in the
system classpath like that. If your class name matched the name of a
class that already exists, including the package name, you could get
unexpected results. It would be like putting a program in QSYS or
something like that. It's just not really a good idea, even for
testing.

I usually just create a directory like /home/MYUSER/Java/classes then
put all my classes in there. Then do ADDENVVAR ENVVAR(CLASSPATH)
VALUE('.:/home/MYUSER/Java/classes/').

that is a default class path for our JVM.  I signed off and signed on, once

when I started it.  Once I've confirmed things working, I planned to move
it to a more appropriate directory, and mess with classpath then.

I'm still on a quest to improve our Excel document creation performance.
I've created the following java program to perform what Scott Klement's
RPG
service program did, to create a text cell, but doing the 4 steps in
Java
to hopefully get improved performance.  I'm having problems either
specifying the java header stuff correctly, or in specifying the RPG
prototype, because I get a java.lang.NoClassDefFoundError: HSSFtext
error
when calling a program using the prototype.  Can anyone see where I'm
going
wrong?

Is the java class that you defined actually in your CLASSPATH?
