[jcifs] Java Webstart Problem

[Adam Augusta]

I'm using JCIFS 1.2.13 so that my client can use HTTP NTLM authentication to
download a PDF from a MS Reporting Services server.  The server's name is
"reportserver".  The client is running on a FreeBSD 6.0 box with JVM
diablo-1.5.0-b01.

When I run the short program below directly using "java", it works without a
hitch.  When I deploy it with Java WebStart, though, it behaves as though I
weren't even using JCIFS.

I suspect WebStart is setting the default Authenticator, and since it can only
be set once, "jcifs.Config.registerSmbURLHandler()" does nothing.  Does that
sound right?  Can anyone suggest a workaround?

public class DownloadTest {
    public static void main(String[] args) {
        URL url;
        String osName = System.getProperty("os.name");
        if (osName == null || !osName.startsWith("Windows")) {
            jcifs.Config.setProperty("jcifs.smb.client.domain", "MYDOMAIN");
            jcifs.Config.setProperty("jcifs.smb.client.username", "MYUSERNAME");
            jcifs.Config.setProperty("jcifs.smb.client.password", "MYPASSWORD");
            jcifs.Config.registerSmbURLHandler();
        }
        byte[] pdfByteArray = null;
        InputStream is;
        ByteArrayOutputStream os;
        try {
            url = new URL(args[0]);
            is = url.openStream();
            os = new ByteArrayOutputStream();

            // Download buffer
            byte[] buffer = new byte[4096];

            // Download the PDF document
            int read;
            while ((read = is.read(buffer)) != -1) {
                os.write(buffer, 0, read);
            }
            // Copy output stream to byte array
            pdfByteArray = os.toByteArray();

            // Close streams
            is.close();
            os.close();

        } catch (IOException e) {
            throw new RuntimeException("FAILURE", e);
        }
    }
}
