Re: Prototyping and Creating integer objects in RPG for callingJavaclasses

Barbara, I HAVE read the whole section.  Perhaps you missed the beginning
of the thread, but I do not claim to be  an RPG programmer nor do I claim
to be a Java programmer.  I just got stuck with trying to make this work.

I have re-read the chapter several times, and it looks as if I need to call
the Java method passing an instance parameter as the first parm.
Unfortunately, the book does not appear to give any examples of calling a
non-static method that does not return a value.  The method is defined as
follows:

public class conversionTest
{

  public conversionTest(File f, int format)


The prototype now looks like this:

D Class1          C                   'conversionTest'
 *  java method
D convert         PR                  ExtProc(*JAVA:
D                                            Class1:'conversionTest')
 *  method parameters
D  f                              O   Class(*JAVA:'java.io.File')
D                                     Const
D  format                       10I 0 Value

And I have defined an object called obj.  However, I don't really know what
to define it as.  I have tried both

D obj             S               O   Class(*JAVA:Class1)

and

D obj             S               O   Class(*JAVA:'java.lang.Object')

Both compile; neither works.

I am calling the method as follows:

c                   callp     convert(obj:fFile:format)

And every time I do, I get a NoSuchMethodError.  But the signature it tells
me it can't find ("(Ljava.io.File;I)V" in class "conversionTest") looks
like the signature I find when I run javap on conversionTest
((Ljava/io/File;I)V).  I'm sure I'm being dense here, but I genuinely don't
know what I'm doing wrong.
