Hi,
I would agree with you completely except that I have no choice in the tools I am using! The original programmer is no longer available and I have to tweak his baby. As I don't know any alternative methods, it should be quicker to learn as much about the tools I am using than to learn about other tools and re-implement the application.
Paul.

Hi,
calling Java from RPG via JNI will startup a JVM in every Job using this and starting maybe hundreds of JVMs won't scale well and only IBM will be happy to sell lots of hardware. Every RuntimeException coming up from Java could not be handled in RPG and will freeze the JVM for all following JNI calls from RPG. The JVM will be started implicit by the RPG runtime when the first JNI call occurs and all following calls within this job have to use this JVM and the associated settings. Using JNI calls in both directions adds addtitional complexity, because RPGs Multi threading capabilities are very limited.
As a conclusion of this all, I would strongly recommend not to use JNI calls from RPG.
