Sure sir, I will sure give it try ... by the way when you open source ,
does it mean it can be used for free in production environment? Any
licensing you enforce? Thanks for your note...

I am calling Java class in a CL program using QSH command... it seems its
starting JVM for each call which is not so good for performance, is there a
way to prevent this so JVM is started once and then all future call is
handled by started JVM instance?

You could use the command RUNJVARUN, it's part of my Open Source project
AppServer4RPG and available at SourceForge. It's running all Java calls in
one prestarted JVM, so you would have very fast responses with nearly
unlimited scalability. As it is running multithreaded in a single JVM, your
java calls must not unload the JVM (System.exit()) and you can't use
System.out for giving back responses.
If you would need more sophisticated parameter handling, it's not too hard
to implement your Java part to run with AppServer4RPG.
