s multi dimensional array from RPGLE (AS400) to java

Question

I have tried many times to pass a multi dimensional array from rpg(AS400) to java,but it didn't works, Is there any possibility to pass multi dimensional array fromRPGLE (AS400) to java can some one help.

I know how to pass a single dimesional array maybe that will help. — danny117, Nov 03 '17 at 14:10
This is really cutting edge stuff for the RPG programmer. There aren't a lot of examples on how to do this in the wild. — danny117, Mar 05 '18 at 17:09

The problem is you are trying to pass something which is a non primitive. In java you would just pass the class to the method or procedure. Where RPG is pretty much limited to passing primitives.

So possibly you could create a constructor for the multi dimensional array that takes an array of string and build the multi dimensional array in java.

Here's how to pass event args which is defined as string[]. I'm only passing one but you could pass more.

d                                             *CONSTRUCTOR)

c     *entry        plist                                            
c                   parm                    path            200      

c/free                                                               
     inputargs(1) = crtstring(%trim(path));                          
                              xls2csv(inputargs);                    
     *inlr = *on;                                     
     return;

Or you can return a multi dimensional array from from a java class and pass that class to the java program. Either way your going to have to make a java class that has a constructor for creating a multi dimensional array class.
