Re: Calling java class through RPGLE...

because the JVM will be restarted in the new job.

Alternatively, if the java program doesn't effect the interactive job, you can make the java app a server job and create a native program (RPG, Cobol, or CL) can send requests to.

This way you only have a single instance of the java app running.

Data queues are my choice for communicating between java & native apps.
