You mean it's still not finding the constructor when you change the
prototype to InputStream?

You have to code the RPG prototype with the same class you coded on the
Java constructor.

      * PageText(int lns, int cols, InputStream data);
     D PageText        PR              O   ExtProc(*JAVA:'PageText':
     D                                             *Constructor)
     D  lines                        10I 0 Value
     D  columns                      10I 0 Value
     D  streamData                     O   Class(*JAVA:
     D                                     'java.io.InputStream')

The prototype can't have a subclass of the class coded on the
prototype.  But the parameter you actually pass on the call itself can
be a subclass.

     D  ByteArrIS      S               O   Class(*JAVA:
     D                                     'ByteArrayInputStream')
            pt = PageText (1 : 2 : ByteArrIS);
