No credentials available for BASIC 'api.constantcontact.com'@api.constantcontact.com:443

No credentials available for BASIC 'api.constantcontact.com'@api.constantcontact.com:443


I'm trying to update our application to use Basic authentication over https.

Two changes have been made:

 1.     URI looks like this now: "https://api.constantcontact.com/ws/customers/ourcompany/activities"

 2.     HttpClient API call has been change to use 'AuthPolicy.BASIC'.

Also, according to this resource: http://hc.apache.org/httpclient-3.x/sslguide.html, with HttpClient, we don't need to do anything extra in order  to use SSL communications.

My problem is that, I'm getting 401 error with the following message:

Jun 20, 2009 12:12:10 AM org.apache.commons.httpclient.HttpMethodDirector processWWWAuthChallenge

INFO: No credentials available for BASIC 'api.constantcontact.com'@api.constantcontact.com:443

Could, please, anybody help me to resolve this issue.


Thanks in advance,



This response indicates that the Basic Authentication is not being set corretly in your HttpClient class.  I would refer to the documentation on that class on how to implement Basic Authentication over a secury connection (https).  Have you tried running the test case they suggested for ensuring your Apache server is set up correctly?

No, I have not ran that test.

Could you please point me where I can find it?

I can't find any other settings for HttpClient in order to set it for basic authentication.

Would it be helpfull if I paste my code for your review?

Dave, I'm not getting anywhere and time is running out.

I'm posting trimmed down version of my code. Could you please take a look and see what is wrong.

public class ConstantContactActivityUpload {

    public void upload(List<ConstantContactUploadInfo> infoList, int listKey) throws IOException {   

    UsernamePasswordCredentials credentials = setCredentials();

    HttpClient httpClient = initialSetUp(credentials);

    AuthDetails authDetails = extractAuthDetails();

        RequestEntity requestEntity ...

    String url = "https://api.constantcontact.com/ws/customers/ourcompany/activities";

    this.postToServer(httpClient, requestEntity, url, uploadedValues.toString());


    private HttpClient initialSetUp(UsernamePasswordCredentials credentials) {

        HostConfiguration hostConfiguration = new HostConfiguration();


        AuthScope authScope = new AuthScope("api.constantcontact.com", 80, "api.constantcontact.com");

        AuthPolicy.registerAuthScheme("Basic", BasicScheme.class);

        HttpClient httpClient = new HttpClient();

        List<String> list = new ArrayList<String>();


        httpClient.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY, list);

        httpClient.getState().setCredentials(authScope, credentials);

        return httpClient;


    private void postToServer(HttpClient client,  RequestEntity requestEntity, String url, String uploadedValues) throws HttpException, IOException {

        PostMethod httpPost = new PostMethod(url);




    private UsernamePasswordCredentials setCredentials() {...} 

    protected AuthDetails extractAuthDetails() {...}



Change the port fom 80 to 443 or to a negative number or to AuthScope.ANY_PORT.
