[SNMP4J] table

[Afnan Chowdhury]

Hi,

thanks Frank for sorting my previous problems. Now I am testing snmp
table with my router to get IP Routing table but the program runs
endless with no result. Could you please highlight where I am getting
worng. I have just add one column to the table request. Following is
the code:

Thanks in advance
