No Exception is thrown!

in SNMP API • 12 years ago

Hey, I'm using the AdventNetSnmp-4.0.3 library and have a question.

If I start my application (accidentally) multiple times the second application just hangs at this call:

private SnmpTrapReceiver receiver;
...
//init and handle all stuff...
...
receiver.setPortWithExceptionMsg(this.listenerPort);

If I read the javadoc for SnmpTrapReceiver, its written that in case of an error an exception should be thrown:

Throws:
SnmpException - if the socket could not be opened, or the socket could not bind to the specified local port.

but this does not happen, tha app just waits/hangs.

any idea how to solve this?

regards
michael

Hi michael,

I too use this api setPortWithExceptionMsg(int port) but i didn't face the issue that you mentioned here.

I'm getting an SnmpException on calling this method with invalid port number or already bound port.

Please check whether the underlying network stack of your OS/machine has any problem, with simple DatagramSocket program. That may help.

Hi,

Greetings.

Please provide us the below details to analyze further on this issue.
--> SNMP API Version.
--> Code Snippet.

NOTE:
SNMP API version can be obtained by the setting AdventNetSnmp.jar and AdventNetLogging.jar as the first entry in the classpath and exceuting the command,
java GetSnmpReleaseVersion
command in the command prompt.

Thanks and Regards,
Pradheep
