How do I convert from java String to RPG character?

["Wills, Mike N. (TC)" <MNWills@xxxxxxxxxxxxxx>]

Hello all, I can't seem to get this to work. I have seen some references to
using Sting.getBytes(), but that doesn't seem to work. 

Here is my subprocedure:
     P*--------------------------------------------------
     P* Procedure name: cvtFromString
     P* Purpose:        Convert from java String to os/400 character
     P* Returns:        Returned os/400 string
     P* Parameter:      javaString => String in java format
     P*--------------------------------------------------
     P #cvtFromString  B                   EXPORT
     D #cvtFromString  PI          3276A
     D  javaString                     O   CLASS(*JAVA: String)
     D                                     CONST

     D newString       PR              O   ExtProc(*Java: String:
*Constructor)
     D  mystring                       O   Class(*Java: String) CONST

     D getBytes        PR         65535A   ExtProc(*JAVA: String:
'getBytes')

     D txtField        S          65535
     D mystring        S               O   Class(*Java: String)

      /FREE

       monitor;
         mystring = newString(javaString);
         txtField = getBytes(mystring);  // debug stmt
         return getBytes(mystring);
       on-error *all;
         return *blanks;
       endmon;

      /END-FREE
     P #cvtFromString  E   

When I check txtField I get '0'. The result should be '7037'. Does anyone
have any ideas what is wrong with my program? There should be a FAQ on this.
