Re: call Java program from RPG

[Richard Shaler <rshaler@xxxxxxxxxxx>]

Great suggestion! Thank you. I thought I would have to destroy the JVM to 
handle garbage collection. Of course, the JVM would then need to be re-started 
for the next method call.
 
Assuming I'm not going to call any more Java methods in the current job, would 
destroying the JVM still be a viable alternative to explicitly cleaning up 
objects?

Richard, don't forget to clean up your objects. Until fairly recently I
thought it was necessary to code explicit frees for every object, but
there's a way to free many objects at once.

| D env s * 

| c eval env = getJniEnv()
| c callp beginObjGroup (env : 10000)
c eval sendMsg = crtString(msg)
...
| c callp endObjGroup (env)
c EVAL *INLR = *ON

See the FAQ for the procedures I've used here, FAQ entry "How do I free
Java objects that I have created from RPG".
