Hi All, I'm facing an issue with SNMP GET. While sending the PDU to the SNMP agent with public ResponseEvent send(PDU pdu, Target target, TransportMapping transport) throws IOException method, i'm getting the following exception.
java.io.IOException: Length greater than 32bit are not supported for integers: at position 49 at org.snmp4j.asn1.BER.decodeInteger(BER.java:627) at org.snmp4j.smi.Integer32.decodeBER(Integer32.java:62) at org.snmp4j.smi.Variable.createFromBER(Variable.java:170) at org.snmp4j.smi.VariableBinding.decodeBER(VariableBinding.java:164) at org.snmp4j.PDUv1.decodeBER(PDUv1.java:169) at org.snmp4j.mp.MPv1.prepareDataElements(MPv1.java:170) at org.snmp4j.MessageDispatcherImpl.dispatchMessage(MessageDispatcherImpl.java:241) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:313) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:276) at org.snmp4j.transport.AbstractTransportMapping.fireProcessMessage(AbstractTransportMapping.java:81) at org.snmp4j.transport.DefaultUdpTransportMapping$ListenThread.run(DefaultUdpTransportMapping.java:282) >From this what I've understood is that, the SNMP agent is returning a value >larger than integer for the attribute that is expected to return an integer >value. This IOException is caught and logged in DefaultUdpTransportMapping. So >in my application I'll get ResponseEvent with a null PDU and i'll throw an >SnmpTimeOutError as the response is null. The problem is that I do not want to show the error as an SnmpTimeOut. I want to show the exact reason in my application. So I tried modifying the code and I threw a RunTimeException from the MessageDispatcherImpl after catching the IOException. Then I got the below log Exception in thread "DefaultUDPTransportMapping_192.168.234.72/0" java.lang.RuntimeException: Length greater than 32bit are not supported for integers: at position 49 at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:324) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:276) at org.snmp4j.transport.AbstractTransportMapping.fireProcessMessage(AbstractTransportMapping.java:81) at org.snmp4j.transport.DefaultUdpTransportMapping$ListenThread.run(DefaultUdpTransportMapping.java:282) My requirement is that if i get an IOException like above I want to throw that exception and catch it in my code so that i can give a clearer message. Is it possible to do that? Can anyone of you help me out with this? Its really urgent. Thanks a lot!! Best regards Shenaz Please do not print this email unless it is absolutely necessary.
