The history of Java WebDav client is discussed well in this blog: http://pragmaticchris.blogspot.com/2007/11/java-webdav-clients.html. There is one update to it though: the JackRabbit project has a well-defined WebDav client (extending Commons HTTP Client) available.

To add JackRabbit WebDav client to your Maven project, use this:

<dependency>
    <groupId>org.apache.jackrabbit</groupId>
    <artifactId>jackrabbit-webdav</artifactId>
    <version>1.6.0</version>
</dependency>

I will show one example of using the WebDav client which I had developed to upload content to an WebDav server:

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.URL;
import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.jackrabbit.webdav.client.methods.PutMethod;

...

// WebDAV URL:
final String baseUrl = ...;
// Source file to upload:
File f = ...;
try{
    HttpClient client = new HttpClient();
    Credentials creds = new UsernamePasswordCredentials("username", "password");
    client.getState().setCredentials(AuthScope.ANY, creds);

    PutMethod method = new PutMethod(baseUrl + "/" + f.getName());
    RequestEntity requestEntity = new InputStreamRequestEntity(
	    new FileInputStream(f));
    method.setRequestEntity(requestEntity);
    client.executeMethod(method);
    System.out.println(method.getStatusCode() + " " + method.getStatusText());
}
catch(HttpException ex){
    // Handle Exception
}
catch(IOException ex){
    // Handle Exception
}
