Basically our company uses IBM iSeries for the majority of our data processing. Almost 99% of our internal applications are written in RPG. We realize IBM is trying to push companies towards Java/J2EE / we're trying to modernize our apps with a GUI interface. Not to beat around the bush but our goal has become to migrate to the GUI interface and move towards Java/J2EE.
This may seem as a more "general question" but has your company gone through a RPG to Java migration? We're just worried that Java might demand too much overhead of the workstation to run effectively and some of our internal apps might break. Let me know your thoughts / experiences.
