RE: Communicating between java & rpg?

["Tanveer, Mohammad" <MTanveer@xxxxxxxxxxxxxxxx>]

Thanks,  I think stored procedures are much simpler than this.  No need for
error trapping and waiting for data (performance), debugging is much
simpler, I am not sure why people want to pass 2200 parameters.  May be a
old design concept. Anyways at least I know how to call an AS/400 program
and pass parameters.  Thanks a lot.

Just wondering have you or anyone else ever configured WCS for VAJava?  I
just can't configured it using the manual.  I badly need help on this IBM
did a great job I mean WCS and VAJava but I don't know why the installation
and setup is so complicated and time consuming for both of them.  Everything
is ok but when I try to hit the page of my store.  I am getting this
message.

Error 500

Pretty simple:

// Initialization - done once

        ProgramCall call = new ProgramCall(new AS400());
        ProgramParameter[] parms = new ProgramParameter[1];
        parms[0] = new ProgramParameter(2200);
        call.setProgram("/QSYS.LIB/APILIB.LIB/RECEIVE.PGM", parms);


// Call

public void receive(byte[] data)                // EBCDIC buffer
        throws Exception
{
        parms[0].setInputData(data);
        if (call.run() == false) {
                throw new Exception("Receive failed.");
        } else {
                data = parms[0].getOutputData();
        }
}
