JBoss + Log4j + SNMPTrapAppender

[Dylan Hansen]

Greetings all,
I've been spending a few days attempting to get Log4j sending SNMP trap 
notifications, and have not had any luck.  I was hoping that someone 
that is subscribed to this list may have the same sort of configuration 
as me, and could point me in the right direction.

Currently we use Log4j for logging in our JBoss 4 environment.  We 
would like to have our JBoss errors sent out as SNMP traps to our 
management host (in our case, we are running OpenNMS).  After many 
failed attempts at not having OpenNMS receive the traps, I've set up 
snmptrapd on a different box and tried sending the traps there.  Again, 
no luck.  Both the OpenNMS and snmptrapd logs showed no activity from 
the sending host.  After much testing and trying, I'm thinking that I 
may have a configuration issue, which is why I decided to post to this 
list.  I'm hoping that someone can point out a flaw in one of my 
configuration files, or let me know of something that I'm missing.

Here is a snippet of my log4j.xml file, located in my 
jboss/server/all/conf directory:

I am running snmpd on the same box that I am running JBoss.  I know I 
am able to send SNMP traps from this box to the management host.  When 
I start/stop the snmp daemon, I can see the traps being received in the 
snmptrapd log.

So, to reiterate, I am sending SNMP traps thusly:
        JBoss --> log4j --> snmptrapd
I am unable to see any output in my snmptrapd log.  Am I missing 
anything noticeable?  Is there anything I need to install on the 
management host side so that it recognizes the log4j traps?  I have 
tried using the "traphandler" directive in my snmptrapd configuration 
by matching up the OIDs, but I haven't had any luck there either.

Any input is appreciated, thank you very much for your time!
