RE: Prototyping and Creating integer objects in RPG for calling Javaclasses -- RPG400-L

Right.  It wouldn't compile because I had the parameter for the newInt
prototype as

D  byes                       9999A   Const Varying

instead of

D  byes                         10I 0 Const Varying

Now it compiles.  When I call it, I get the following error:

the
   RPG prototype for the method, or change the Java method, so that the
return

the
   methods in class XYZ using command QSH CMD('javap -s XYZ').

Running the following command:
qsh cmd('javap -s conversionTest')

Gives me this output:
   Compiled from conversionTest.java
   public synchronized class conversionTest extends java.lang.Object
       /* ACC_SUPER bit set */
   {
       public conversionTest(java.io.File,int);
           /*   (Ljava/io/File;I)V   */
       public static void main(java.lang.String[]);
           /*   ([Ljava/lang/String;)V   */
   }

Obviously, the signatures do not match.  Should I post the source for
conversionTest.java?  Should I take this thread to the Java list?

Based on what you copied you created a ten character alpha field.
Right?

This is not what I said.

If you have an Integer to define it is (10I 0)

You originally stated that you were using (5I 0) which is not a Integer
it is a small integer.

Andrew,

Thanks for getting back to me so fast!

I changed
D xformat         S              5

to
D xformat         S             10

I still get the java.lang.NoSuchMethodError

Integer is defined as 10I 0

Small Integer is 5I 0

Change it to 10

Subject: Prototyping and Creating integer objects in RPG for calling
Java classes

I'm having some trouble calling a Java class that takes an int as one of
its inputs.  I have tried the following as the prototype for the method
parameter:

D  format                         O   Class(*JAVA:'java.lang.Integer')
D                                     Const

and this for the constructor:

D newInt          PR              O   ExtProc(*JAVA:
D                                             'java.lang.Integer':
D                                             *CONSTRUCTOR)
D                                     Class(*JAVA:'java.lang.Integer')
D  byes                       9999A   Const Varying

Here's the declaration for the field I'm using as the input parm for the
RPG program:

D xformat         S              5
 * I would think this should be 5I 0 or 5S 0, but it only compiles if I
declare this as alpha.

Here's the declaration for the variable I'm using as the input parm for
the
Java class:

D sFormat         S               O   Class(*JAVA:'java.lang.Integer')

And finally, here's how I'm trying to create the java.lang.Integer
object.

C                   Eval      sFormat   = newInt(xformat)

If it's not yet obvious, I really don't know what I'm doing here.  I'm
trying to adapt another RPG program we're using that calls a Java class,
but that one only uses strings.  I'd be happy to post all of the source
on
request.

Thanks!

Mike E.
