WebDAV client sharepoint server

Greetings - I'm hoping anyone can help me.   I've googled, read
/searched the back archives and I'm still not working.  I have to upload
files to Microsoft sharepoint from a java program.   Based on my
research I fully expected having to turn of the expect-continue
functionality but apparently I'm doing it all wrong here.   
 
Details: 
slide 2.1 client lib
NTLM authentication
 
 
Output below is typical:
 
Uploading 'C:\coLinux\cofs.txt' to 'http://psosupport/Shared
Documents/cofs2.txt' 
Dec 10, 2006 11:22:10 PM
org.apache.commons.httpclient.auth.AuthChallengeProcessor
selectAuthScheme
INFO: ntlm authentication scheme selected

readResponse

Example simple code I've tried to use (I've tried many variations but
this is the current one)
 
package org.apache.webdav.cmd;
 
import java.io.File;
import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HttpURL;
import org.apache.commons.httpclient.HttpsURL;
import org.apache.commons.httpclient.NTCredentials;
import org.apache.commons.httpclient.URIException;
import org.apache.webdav.lib.WebdavResource;
 
public class SimpleTest {
 
public static void main(String[] args) {
String uri = "http://psosupport.visionael.com";
try {
String dest = "http://psosupport/Shared Documents/cofs2.txt";
String src = "c:/colinux/cofs.txt";
File file = new File(src);
 
if (file.exists()) {
System.out.println("Uploading '" + file.getCanonicalPath()
+ "' to '" + dest + "' ");
WebdavResource webdavResource = null;
try {
NTCredentials creds2 = new NTCredentials("myusername", "mypassword",
"hostname", "ntdomain");// tried both the client hostname and the server
hostname 
webdavResource = new WebdavResource(
"http://psosupport/Shared Documents/", creds2);
webdavResource.retrieveSessionInstance()
.getHostConfiguration().getParams().setParameter(
"http.protocol.expect-continue",
Boolean.FALSE);
if (webdavResource.putMethod(file)) {
System.out.println("succeeded.");
}
} catch (Exception e1) {
System.out.println(e1.getMessage());
}
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
