IPC$ is often not displayed when browsing in Network Neighborhood (may
depend on client OS); you could try the following:

import jcifs.Config;
import jcifs.smb.SmbFile;

public class ListShares {

    public static void main(String[] args) throws Exception {
        Config.setProperty("jcifs.smb.client.username", args[0]);
        Config.setProperty("jcifs.smb.client.password", args[1]);
        SmbFile[] shares = new SmbFile("smb://").listFiles();
        for (int i = 0; i < shares.length; i++) {


Stick your jCIFS parameters from web.xml into a .properties file, and run:

    java -Djcifs.properties=myparams.properties ListShares username password

If "smb://$/" is listed, then everything should be
working; if you get errors, or IPC$ isn't listed, that may point to
your problem.
