[SNMP4J] help in getTable

[Lauryca Puyulik]

Hi, I`m new in snmp4j and I have some questions regarding to table() method from SnmpRequest. When I used this method, my response was :
14:49:57,296 INFO  [STDOUT] Table received in 1500 milliseconds.
14:49:57,906 INFO  [STDOUT] Table walk completed with status -4. Received 0 rows.

1. Why 0? 
2. What`s means status 4?
3. The pduType = PDU.GETBULK (is my default pduType) is correct?
4. To use .1.3.6.1.2.1.2.2 as the base is correct?

Thanks!
