Heh. One of the few things I can guarentee about this is that there's
only ONE instance of this class that exists.

And you presume...wrong. How does one invoke an RPG program statically?
I didn't even know you could do that....

And I'm presuming that GWBA09D5 includes the STATIC keyword for this
nvocation of the program. Is that correct? Also, do you have other
copies f the class laying around in the CLASSPATH? Perhaps the RPG
program is inding a different version of ResendOrder than the one that
you're running avap on?

I'm not getting a stack trace, since the method is never getting
invoked.

Here's the error I'm receiving:

Message ID . . . . . . : RNX0301

Message . . . . : Java exception received when calling Java method.

Cause . . . . . : RPG procedure GWBA09D5 in program MXMLIB/GWBA09D5
received
Java exception "java.lang.NoSuchMethodError: resendOrder" when
calling
method "resendOrder" with signature
"(Ljava.lang.String;Ljava.lang.String;)Ljava.lang.String;" in class
"com.WMS_BPCS_Integrator.executable.ResendOrder".

Which, based on all the documentation I've been reading, means the
signatures don't match. But here's the result from the javap command:

Compiled from "ResendOrder.java"
public class com.WMS_BPCS_Integrator.executable.ResendOrder extends
java.lang.Object{ public
com.WMS_BPCS_Integrator.executable.ResendOrder();
Signature: ()V
public static java.lang.String resendOrder(java.lang.String,
java.lang.String );
Signature: (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
}

Press ENTER to end terminal session.

As far as I can tell, the signatures match. I haven't misspelled the
method name. And the class is being found (I tested that by changing
the class name in the procedure and got a class not found error). Maybe
there's something odd about the configuration on this iSeries or
something. I don't know. But regardless of how I configure this, I get
the same error over and over and over again.
