The V5R3 version of the "RPG and Java" documentation is better, and it
all applies to V5R1 except the information about the
QIBM_RPG_JAVA_EXCP_TRACE environment variable.

I would still let RPG start the JVM, and just make sure the CLASSPATH
environment variable is set to the classpath you want.  If you get the
CLASSPATH environment variable set up at the start of the job, you don't
need to worry about the setup in your individual programs.

But make sure the CLASSPATH includes the classes for all the programs
that might need to call Java in a job.  It can be dangerous working in
V5R1 where you can usually get away with starting a new JVM for each
program.  Design for the future (V5R2+) where you can't do this.
