Deliver_SM_Resp about smppsim

@hajlaoui-nader I played with SMPPSim about one year ago and now I cannot setup the environment to run this. All I can find is the following method invokes getStringValueFixedLength

public void demarshall(byte[] request) throws Exception {

    // demarshall the header
    super.demarshall(request);
    // now set atributes of this specific PDU type
    int inx = 16;
    try {
        message_id = PduUtilities.getStringValueFixedLength(request, inx, 1);
    } catch (Exception e) {
        logger.debug("DELIVER_SM_RESP PDU is malformed. message_id is incorrect");
        throw (e);
    }

}

the "startPoint + actualLength" is a fixed number, it is always 17. It seems like the length must be smaller than 17. Have you tried comment out this throw exception code OR modify the last two parameters to bigger number in PduUtilities.getStringValueFixedLength(request, inx, 1)?

No i haven't tried this. But can you explain why it's fixed to 17 ?

@hajlaoui-nader To be honest, I have no idea why it is fixed length, you can check its official website, it has some documents there, it may help you to figure it out. For me, I was using this SMPPSim as a simulator program to test my side program. I only switched it to slf4j logger which helped me to track what exactly happened in each class. The limitation of this SMPPSim that I found is when TPS is greater than 5000 and leave it running a few days, it will die itself.

yes. i figured this out. Anyway, thank you for your answer :))
