For the values in web.xml, they should be:

jcifs.netbios.wins -- comma-delimited list of WINS servers in your
environment.  Localhost will almost certainly not be correct.  From a DOS
prompt you can do:

    ipconfig /all

which should list a "Primary WINS Server" entry you can use.

should be the domain, username, and password for a real account in
environment (you probably already have this specified; just confirming that
you did replace the "real" values for the example ones below).
