Description

When using INFORMs instead of TRAPs the component must response to the Message. Otherwise the sender tries to send the same INFROM x-times and it will be processed x-times in the SNMP-Component.

The code below is taken from an example:

			if ((pdu.getType() != PDU.TRAP) &&
					(pdu.getType() != PDU.V1TRAP) &&
					(pdu.getType() != PDU.REPORT) &&
					(pdu.getType() != PDU.RESPONSE)) {
					pdu.setErrorIndex(0);
					pdu.setErrorStatus(0);
					pdu.setType(PDU.RESPONSE);
					StatusInformation statusInformation = new StatusInformation();
					StateReference ref = e.getStateReference();
					try {
						e.getMessageDispatcher().returnResponsePdu(e.
							getMessageProcessingModel(),
							e.getSecurityModel(),
							e.getSecurityName(),
							e.getSecurityLevel(),
							pdu,
							e.getMaxSizeResponsePDU(),
							ref,
							statusInformation);
						System.err.println("Response sent");
					}catch (MessageException ex) {
						System.err.println("Error while sending response: "+ex.getMessage());
					}
				}
            processPDU(pdu);

In this case the component sends a response to the sender before processing the message.
