Yea, I have a CL that I prototype right into my source. I haven't done it
that much either, so the same CL works for everything.

Thanks,

I haven't spent a whole lot of time calling java methods from RPG. Just
enough so that every time I need to do this, I have to stop and think for
about half an hour about how I did it the last time. Anyway...because I am
ALWAYS running into CLASSPATH problems (The CLASSPATH concept is my own
personal Kryptonite) I now just add the classpath to the path as the very
first step in my RPG program before I do anything else.

Example:

      * Declare object refernce variable
     D obj_ref         S               O   CLASS(*JAVA:'PFProJava4')
     D string          S               O   CLASS(*JAVA:'java.lang.String')
     D bytes           S               O   CLASS(*JAVA:'java.lang.String')

      * Prototype procedure to create java String object
     D newString       PR              O   EXTPROC(*JAVA:
     D                                             'java.lang.String':
     D                                             *CONSTRUCTOR)
     D                                     CLASS(*JAVA:'java.lang.String')
     D charParm                    1000A   CONST VARYING

      * Prototype a GetBytes method
     D toBytes         PR          1000a   EXTPROC(*JAVA:
     D                                     'java.lang.string':
     D                                     'toBytes') VARYING
      *
      * Prototype procedure to instantiate 'PFProJava' class
     D PFProJava       PR              O
     D                                     EXTPROC(*JAVA:
     D                                             'PFProJava4':
     D                                             *CONSTRUCTOR)

      * Prototype procedure to accept the credit card info STRING Object
     D PFProAut        PR          1000a
     D                                     EXTPROC(*JAVA:
     D                                             'PFProJava4':
     D                                             'autCard')
     D stringParm                          LIKE(string)

     D Apost           S              1a   Inz('''')
     D CmdString       S           1000a
     D Cmds            PR                  ExtPgm('QCMDEXC')
     D   command                   1000A   const
     D   length                      15P 5 const

  /Free

       CmdString = 'ADDENVVAR ENVVAR(CLASSPATH) VALUE(' + Apost +
        '/QIBM/ProdData/Java400/jsse1.0.3_02/lib/jcert.jar:' +
        '/QIBM/ProdData/Java400/jsse1.0.3_02/lib/jnet.jar:' +
        '/QIBM/ProdData/Java400/jsse1.0.3_02/lib/jsse.jar:' +
        '/QIBM/ProdData/Java400/verisign/payflowpro/java/Verisign.jar:' +
        '/QIBM/ProdData/Java400/verisign/payflowpro/java/' +
        Apost + ') REPLACE(*YES)';

        Callp Cmds(CmdString:1000);


        // Convert alphanumeric string to java String object
         string = newString(Input_String);

        // Instantiate the 'PFProJava' class
         obj_ref = PFProJava();

        //  Call the 'main' method in class 'PFProJava'
        Response = PFProAut(obj_ref:string);

That was my first instinct as well, but I can't see how the 'main' method
would work if it were a classpath issue.
