How to define a java array in RPG

It's simpler than you would think. An array in RPG is defined using the DIM
keyword, so you just add the same keyword to the prototype. You do have to
define the length of the array in RPG, which can cause some issues when java
is expecting to receive the exact number of elements filled instead of
receiving blank elements in the array.

Your prototype would look something like: (forgive the fixed form)

d addConditionalFormatting...
d pr like(jint)
d EXTPROC(*JAVA:
d 'MyClass.addConditionalFormatting':
d 'close')
d prRegions like(CellRangeAddress) dim(5)
d prRule like(ConditionalFormattingRule)

I cross posted this in the Midrange, RPG, and Java lists because Java
doesn't get much traffic. Answer wherever you feel is most appropriate.

I need to call a java method with the following signature:

int addConditionalFormatting(CellRangeAddress[] regions,
ConditionalFormattingRule rule)

How do I (or maybe more appropriately, can I) write a prototype in RPG for
the first parameter which is an array?
