Hi David

I have not worked with Java on AS/400. But, based on the code given,
variable "str1" should be "string1". Or declare variable "str1".

Thanks & Regards
Siva

Subject: Calling Java from RPG

(originally posted to JAVA400-L, with crosspost, but news server doesn't
support crossposting yet)

Folks:

Anyone done extensive work with calling Java code from a RPG program (in
V5R1)?

I'm trying to call a simple java method from RPG, but keep getting
exceptions.

My java method is defined as such ...

D data            s               O   class(*java:'Storage')
D manipulator     S               O   class(*java:'Manipulator')
D setString1      pr                  extproc(*java:'Manipulator':
D                                             'setString1')
D  string1                     128A   const varying

... and it's called like this ...

C                   eval      manipulator = newManipulator
C                   eval      data = newStorage(manipulator)
C                   eval      str1 = '12345'
C                   callp     setString1(manipulator:str1)

The call to newManipulator and newStorage work fine, but when I call
setString1, I get a null pointer exception.

On a similar note, anyone know how to debug a java method that is called
from RPG?  I tried to compile the java with a -g switch, and use F22 to
step
into the method, but it didn't work.

Thanks!

david
