org.apache.http.auth Problem

Question

Hi, I used org.apache.http.auth and develop demo code samples like this:

        DefaultHttpClient httpclient = new DefaultHttpClient();

    httpclient.getCredentialsProvider().setCredentials(
            new AuthScope("www.yemeksepeti.com", 80), 
            new UsernamePasswordCredentials("*******", "*******"));

    BasicHttpContext localcontext = new BasicHttpContext();


    BasicScheme basicAuth = new BasicScheme();
    localcontext.setAttribute("preemptive-auth", basicAuth);

    // Add as the first request interceptor
    httpclient.addRequestInterceptor(new PreemptiveAuth(), 0);

    HttpHost targetHost = new HttpHost("www.yemeksepeti.com", 80, "http"); 

    HttpGet httpget = new HttpGet("/YemeksepetiCatalogWebService/CatalogExportMobile.asmx/Mobile_GetCities");


    String responseStr = "";

    HttpResponse response = httpclient.execute(targetHost, httpget, localcontext);
    HttpEntity entity = response.getEntity();
    InputStream is2 = response.getEntity().getContent();
    BufferedInputStream bis2 = new BufferedInputStream(is2);

    ByteArrayBuffer baf2 = new ByteArrayBuffer(1000);

    int current = 0;

    while ((current = bis2.read()) != -1)
    {
        baf2.append((byte) current);
    }
    responseStr = new String(baf2.toByteArray());

    if (entity != null) {
        entity.consumeContent();               
    }

    httpclient.getConnectionManager().shutdown();      

and add a class :

 static class PreemptiveAuth implements HttpRequestInterceptor {

    public void process(
            final HttpRequest request, 
            final HttpContext context) throws HttpException, IOException {

        AuthState authState = (AuthState) context.getAttribute(
                ClientContext.TARGET_AUTH_STATE);

        // If no auth scheme avaialble yet, try to initialize it preemptively
        if (authState.getAuthScheme() == null) {
            AuthScheme authScheme = (AuthScheme) context.getAttribute(
                    "preemptive-auth");
            CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                    ClientContext.CREDS_PROVIDER);
            HttpHost targetHost = (HttpHost) context.getAttribute(
                    ExecutionContext.HTTP_TARGET_HOST);
            if (authScheme != null) {
                Log.v("TANIMLAMA OZGE","target host" + targetHost.getHostName() +" "+ targetHost.getPort());
                Credentials creds = credsProvider.getCredentials(
                        new AuthScope(
                                targetHost.getHostName(), 
                                targetHost.getPort()));
                if (creds == null) {
                    throw new HttpException("No credentials for preemptive authentication");
                }
                authState.setAuthScheme(authScheme);
                authState.setCredentials(creds);
            }
        }

    }

} 

}

But it gives that messages; I couldn't solve the problem. Have you any idea?

Authentication error: basic authorization challenge expected, but not found Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required.
