[SNMP4J] Not able to send SNMP Trap Using DefaultTcpTransportMapping

[Frank Fock]

Hi,

What means "unable to send"? Do you get an error message?
What type of trap receiver are you using?
What versions on both sides?

Have you realized that you are closing the TCP connection right after 
you have successfully send
the message? Sending the message does not mean that the receiver has 
already processed it!
When you close the connection, the receiver will by interrupted and 
probably (most likely)
drop the unprocessed message before processing it.

Best regards,
Frank
