[SNMP4J] Exception while running TestAgent

[priyanka maheshwari]

Thanks Matthieu
but now i am having another problem. Where can i found the files SNMP4JTestAgentBC.cfg and SNMP4JTestAgentConfig.cfg? And how can i visualize it as an SNMP agent? I mean how can i send SNMP traps to other system??

Hi, it is a bug in the agent, here is the fix that Frank Fock will put in the next release

"The  correct implementation of the MOScalar.isVolatileByDefault method
should have read as follows:

 private static boolean isVolatileByDefault(Variable value) {
   if (value == null) {
     return true;
   }
   switch (value.getSyntax()) {
     case SMIConstants.SYNTAX_COUNTER32:
     case SMIConstants.SYNTAX_COUNTER64: {
       return true;
     }
     default:
       return false;
   }
 }

Today I downloaded the snmp4j agent api and when I tried to run org.snmp4j.agent.test.TestAgent.java, It gives the following exception:

0 [main] INFO org.snmp4j.agent.BaseAgent  - Engine boots is: 5
15 [main] INFO org.snmp4j.agent.BaseAgent  - Wrote boot counter: 6
94 [main] DEBUG org.snmp4j.security.Salt  - Initialized Salt to b1318c040edee10a.

        at org.snmp4j.agent.test.TestAgent.main(TestAgent.java:273)

And can anybody also explain the TestAgent.java that how it can be used as SNMP agent.

Thanks
