Calling Java from RPG - CLASSPATH Problem?

["Shannon O'Donnell" <sodonnell@xxxxxxxxxxxxxxx>]

Hi,

I have been able to successfully call a java app from a CL program, after much 
finagling of the CLASSPATH.

Now I want to do the same thing in RPGIV, but running into a CLASSPATH (I 
guess...) problem again.  I've included the code here since it's short, and 
hopefully someone will be able to point out an error or two I might be making. 
Basically though, when I run it, I get an error:  "...received Java exception:  
"java.lang.NoClassDefFoundError:" when calling method "<init>" with signature 
"()V" in class 
"/QIBM/ProdData/Java400/verisign/payflowpro/Java/PFProJavaReturns".

Here's the java code and the RPG code. Both are short....

====================================================
import com.Verisign.payment.PFProAPI;
class PFProJavaReturns {
 // Set defaults
 static String HostAddress   = "test-payflow.verisign.com";
 static Integer HostPort = Integer.decode("443");
 static String ParmList      = "";
 static Integer Timeout = Integer.decode("30");
 static String ProxyAddress  = "";
 static Integer ProxyPort = Integer.decode("0");
 static String ProxyLogon    = "";
 static String ProxyPassword = "";
 static String ReturnResponse = "";

   public static void main(String InputParms[])
   {
    // Place the arguments in the correct variables

  try {
   HostAddress   = InputParms[0];
   HostPort       = Integer.decode(InputParms[1]);
   ParmList      = InputParms[2];
   Timeout       = Integer.decode(InputParms[3]);
   ProxyAddress  = InputParms[4];
   ProxyPort     = Integer.decode(InputParms[5]);
   ProxyLogon    = InputParms[6];
   ProxyPassword = InputParms[7];
  } catch (Exception e) { }

               PFProJavaReturns c = new PFProJavaReturns();
   }

   public PFProJavaReturns()
    {
      String responses = autCard();
    }

// *CONSTRUCTOR With ZERO Parms
  protected String autCard()
     {          
         PFProAPI pn = new PFProAPI();
        // Set the certificate path
        
pn.SetCertPath("/QIBM/ProdData/Java400/verisign/payflowpro/java/certs/");
  // Call the client.
  pn.CreateContext(HostAddress,
                         HostPort.intValue(),
                         Timeout.intValue(),
                         ProxyAddress,
                         ProxyPort.intValue(),
                         ProxyLogon,
                         ProxyPassword);
  String rc = pn.SubmitTransaction(ParmList);
  ReturnResponse = rc;
  pn.DestroyContext();
  return ReturnResponse;
     }


// *CONSTUCTOR with All Parms

  protected String autCard(String args[])
     {    
         try {
   HostAddress   = args[0];
   HostPort      = Integer.decode(args[1]);
   ParmList      = args[2];
   Timeout       = Integer.decode(args[3]);
   ProxyAddress  = args[4];
   ProxyPort     = Integer.decode(args[5]);
   ProxyLogon    = args[6];
   ProxyPassword = args[7];
  } catch (Exception e) { }
         
   PFProAPI pn = new PFProAPI();
   // Set the certificate path
   pn.SetCertPath("/QIBM/ProdData/Java400/verisign/payflowpro/java/certs/");

  // Call the client.
  pn.CreateContext(HostAddress,
                         HostPort.intValue(),
                         Timeout.intValue(),
                         ProxyAddress,
                         ProxyPort.intValue(),
                         ProxyLogon,
                         ProxyPassword);

  String rc = pn.SubmitTransaction(ParmList);
  ReturnResponse = rc;
  pn.DestroyContext();
  return ReturnResponse;
 }
}
