Not at the moment...

I think you're looking for these lines in SnmpRequest.java:
   public synchronized void processPdu(CommandResponderEvent e) {
     PDU command = e.getPDU();
     if (command != null) {
       System.out.println(command.toString());

> But on the side of the snmptrapd I get:

> usm: Unknown User(mtest)

> createUser -e 0x0102030406 mtest MD5 mprueba DES mprueba
                 ^^^^^^^^^^^^
If you didn't modify the SNMP4J tool to use that engineID it won't work. 
SnmpRequest uses the engineID returned from MPv3.createLocalEngineID(). 
So either change the snmptrapd.conf or SnmpRequest.java.
