Calling Java set and get Method from ile RPG

Question

I work on a crossover communication with ile RPG and Java. I want to call a Class in a .jar File with some String Parameter and want to return a String to my RPG programm.

I get a Problem in my set Method. I cant call this method from RPG.

My "getOut()" method call, worked well. I get the right jString back. The CLASSPATH set is right.

Take a look on my Code:

RPG Code:

    D FirstCall       S               O   Class(*Java:'FirstCall') 
    D FirstCall1      S                   LIKE(FirstCall)

            public static void main(String[] args) throws Exception{
            }

            public FirstCall(){
            }

        public String getOut(){
            return sOut;
        }

        public  void setOut(String sIn){
            sOut = sIn + " - java";
        }
    }

Answer 1

The setOut prototype should not have a return value. Remove the "O" from the setOut line.

D setOut          PR                  EXTPROC(*JAVA:                    
D                                             'FirstCall':              
D                                             'setOut')                 
D  strparm                        O   Class  (*Java:'java.lang.String') 
D                                     CONST
