java.lang.NoSuchMethodError

Not quite sure where this should be posted. Here or RPG list, but I'll
start here. 
I have a really simple java method that I am trying to run from an RPG
program. I am able to run it when testing in WSDC, but I am not able to
run it from my RPG program. I keep receiving the error:
Java exception "java.lang.NoSuchMethodError: printConfirm" when calling
method "printConfirm" with signature "()S" in class "ordconfirm".      
My interpretation of this error is that the printConfirm method cannot
be found and that it has a data type of short as the signature. My
initial check was to verify my classpath, which looks correct.
I'm not sure where to look next.

Here is the java class 
 
public class ordconfirm{
        public static void main (String args[]){
        
          short returnCode = 0; 
          returnCode = printConfirm();
        }
  
        public static short printConfirm () {
           short retval = 0;
           
           try{
                //Code omitted     
           }
           catch (Exception de) {de.printStackTrace();}
              
           return retval;       
        }                       
}

Here is the RPG prototype

D OrdPrtConfirm   PR             5I 0 ExtProc(*JAVA:'ordconfirm':
D                                            'printConfirm')
D                                     STATIC
D jRtnCode        S              5I 0

Assuming I have my classpath setup correctly shouldn't the following
line execute the printConfirm method and at least not throw the error I
am receiving?
jRtnCode = OrdPrtConfirm(); 

Do I need to use a *CONSTRUCTOR to first instantiate the ordconfirm
class, or is that only necessary for classes that are not static?
Any help is greatly appreciated.
