[mb-devel] Using the Webservice Digest Authentication

Ok, set up new user on the test server, I assume the realm is still 
musicbrainz.org not test.muiscbrainz.org, and tried out the Apache library
and it is now attemping to do digest authentication, but failing, I post 
the code and output just in case anyone has any ideas but I shall post 
this at the Apache site.

Thanks Paul


Code here:

public static void main(String []args) throws Exception
{
//For debugging
System.setProperty("org.apache.commons.logging.Log", 
"org.apache.commons.logging.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.showdatetime", 
"true");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", 
"debug");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.commons.httpclient", 
"debug");

URL url = new URL("http://test.musicbrainz.org/ws/1/track/");
HttpClient httpClient = new HttpClient();
List authPrefs = new ArrayList(1);
authPrefs.add(AuthPolicy.DIGEST);
httpClient.getParams().setParameter(AuthPolicy.AUTH_SCHEME_PRIORITY, 
authPrefs);
final String username = "testuser100";
final String password = "testuser100";
Credentials credentials = new UsernamePasswordCredentials(username, 
password);
AuthScope authScope = new AuthScope(url.getHost(), 
url.getPort(),"musicbrainz.org");
httpClient.getState().setCredentials(authScope, credentials);

PostMethod postMethod = new PostMethod(url.toExternalForm());
postMethod.setDoAuthentication(true);
postMethod.addParameter("client","TestProg1");
postMethod.addParameter("puid","4d8cad37-054d-4421-855e-60f111cf574a 
B2660da86-081f-eca6-12c7-739b37228326");



try
{
int result = httpClient.executeMethod(postMethod);

if (result != 200)
{
System.out.println("erro handling: " + result
+ postMethod.getStatusText());
}
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
postMethod.releaseConnection();
}
}
