Here i am trying to read the list of sharepoint. For this i have done the following: I have downloaded the WSDL file which i got from The URL like: sharepointsite.com/_vti_bin/Lists.asmx?WSDL. and i have executed the following command to generate the classes in the directory “C:\Program Files\Java\jdk1.6.0_12\bin\wsimport.exe” -p com.microsoft.schemas.sharepoint.soap -keep -extension Lists.wsdl. Imported those classes in my eclipse IDE java application.

and i have written the following code

/* Creates a port connected to the SharePoint Web Service given.

 * Authentication is done here. It also prints the authentication details

 * in the console.

 * @param userName SharePoint username

 * @param password SharePoint password

 * @return port ListsSoap port, connected with SharePoint

 * @throws Exception in case of invalid parameters or connection error.

 */

public static ListsSoap sharePointListsAuth(String userName, String password) throws Exception {

    ListsSoap port = null;

    if (userName != null && password != null) {

        try {

            Lists service = new Lists();

            port = service.getListsSoap();

            System.out.println("Web Service Auth Username: " + userName);

            ((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, userName);

            ((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);

        } catch (Exception e) {

            throw new Exception("Error: " + e.toString());

        }

    } else {

        throw new Exception("Couldn't authenticate: Invalid connection details given.");

    }

    return port;

}

I am getting following exception :

Web Service Auth Username: "domain\username" java.lang.Exception: Exception. See stacktrace.javax.xml.ws.soap.SOAPFaultException: Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.

    It would be helpfull if i get the specific exception from the server.With this expection i am unable to track my pgm. 
    I dont know where did i go wrong?  am i missing anything ?  any configuration is required ?

    Thanks in advance for your help

I had the same problem, try with an Authenticator :

new BasicAuthentication(userName,password).authenticate();

My BasicAuthentication class :

import java.net.Authenticator;
import java.net.PasswordAuthentication;

public class BasicAuthentication extends Authenticator
{
    private String username;
    private String password;

    public BasicAuthentication(String username, String password)
    {
        this.username = username;
        this.password = password;
    }

    public PasswordAuthentication getPasswordAuthentication()
    {
        return (new PasswordAuthentication(username,password.toCharArray()));
    }

    public void authenticate()
    {
        Authenticator.setDefault(this);
    }
}
