Looking good. Just call it now with someplace for the result to go.
Result = ResendOrder(ReturnMsg:string(wmfac):string(charOrd));
Having a result variable is part of the signature, too. CALLP implies a void return.

Subject: Re: Signature mismatch when calling java prototype
Ok, here's what we've got so far. I'm still getting the same NoSuchMethod error, but the signatures still match.
The prototypes:
d Instantiate pr o extproc(*JAVA:
d 'com.WMS_BPCS_Integrator.ex-
d ecutable.ResendOrder':*constructor)
d ResendOrder pr o extproc(*JAVA:
d 'com.WMS_BPCS_Integrator.ex-
d ecutable.ResendOrder':'resendOrder')
d class(*JAVA:'java.lang.String')
d o class(*JAVA:'java.lang.String')
d const
d o class(*JAVA:'java.lang.String')
d const
d string pr o extproc(*JAVA:
d 'java.lang.String':
d *CONSTRUCTOR)
d value 32000a const varying
The procedure calls:
callP SetEnvVar(); (this just sets up the home directory and classpath)
callP Instantiate();
ResendOrder(ReturnMsg:string(wmfac):string(charOrd));
The declaration of the java class and method:
public class ResendOrder
{
public String resendOrder(String Facility,String Order)
{...}
}

Ok, I'm officially at my wits end. I've written a java class which ccepts an array of string objects and returns a string. Here is the rototype in the RPG program:
Mike, I'm a bit confused about what you said here. You said that the ava class returns a string. Normally, I'd just think you meant to say java method", but since you used the name "main" for the method, I'm ondering if you're hoping that you can also use the RUNJVA command to all this main method and get the value back.
I tried creating a Java class with a main method like yours, and it reated the Java class ok, and I was able to call the main method with our prototype after I added the STATIC keyword in RPG (and changed the ame of the class to my class's name).
But I wasn't able to use RUNJVA to call the class method. I had to hange the method to have the usual signature before I could use RUNJVA o call the class.
public static void main(String args[]) So I'm thinking that your Java method will be easier to understand if ou use the name "resendOrder" for that method, instead of using the ame "main", since using the name "main" could cause confusion.
