Calling JAVA methods with varargs from RPG

[not3baddad]

Hello All

I'm trying to call a JAVA method from RPG but keep getting a null pointer exception.

The JAVA method is defined thus (simplified):

public Object myMethod (Object... objects) {}

I have defined the input parameter in the corresponding RPG procedure interface as

class(*JAVA:'java.lang.Object') const dim(32767)

When calling the method I pass a %subarr so as to only pass the number of elements populated with objects, but always get a null pointer exception.

Does the procedure definition need to be different when dealing with a JAVA method that uses varargs for the input parameters?

Managed to figure this out in the end. I had to add options(*varsize) on the procedure definition parameter:

 
 class(*JAVA:'java.lang.Object') const dim(32767) options(*varsize)

It's likely the use of varargs on the Java method definition was a red herring.
