Re: Initiating SOAP Request from RPG Using Sockets

Andy,

Just because an RPG program is a separate module does not mean that it
needs to be started up / instantiated every time.  For years now I have
been creating RPG programs that include a mode parameter in their entry
list.  The mode indicates what needs to be done, to include having a
mode to terminate the program (along with any programs it has called).

I would think that as long as the RPG program stays open that the JVM
would similarly stay open.  If you need an example of the RPG logic
just send me an e-mail.
