[SNMP4J] How to send synchronous SNMP GET response?

[Ivan Mladenović]

Hello,

Could somebody give me some example how to send GET request, by using
SNMP4J?

I try following things:

ResponseEvent response = snmp.send(pdu, target);

and

ResponseListener listener = *new* ResponseListener() {

*    *@Override

*    public* *void* onResponse(ResponseEvent event) {

*     * PDU response = event.getResponse();

    }

};



listener.onResponse(session.send(pdu, target));



Also, I try all examples from book “Essential SNMP, 2nd Edition“, and all
examples I was found on the internet.

But, every time I get same result. I get the response event, but response
PDU is always null. When I try this by MIB browser it is working properly.

It looks like when I send request  my application does not wait to get
proper response.


Could anyone give me some example of how to send SNMP GET request by using
SNMP4J library?

Or, could anyone recommend some SNMP books about this?

Thanks in advance.



Ivan
