[SNMP4J] Unsupported address class (transport mapping)

[Carlos Vicente]

Greetings,

 

I've just recently started my way into SNMP protocol (newbie as a newbie
can get :-P). After some reading, I created a MIB file, and had a quick
look through libsmi library (since the agents will be implemented in C
or C++).

Since my main task is to create a JAVA manager, I got started with
SNMP4J, and I'm already having some problems.

 

After calling ():

 

            Snmp snmp = new Snmp(new DefaultUdpTransportMapping());

 

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

 

The following exception is thrown: 

 

org.snmp4j.transport.UnsupportedAddressClassException: Unsupported
address class (transport mapping): org.snmp4j.smi.TcpAddress

 

 

I'm using TcpAddress class to resolve a DN. After the name is resolved I
just pass the IP address to the CommunityTarget instance through
setAddress. I've also tried to use IpAddress, with the same result
(can't add a port number with this class but just wanted to check the
results).

 

This is probably too obvious for you guys, but I would appreciate any
help on the subject.

 

Thanks in advance,

 

            Carlos Vicente
