Why the 401 exception after authenticating?

[Thomas Kennedy]

I can authenticate to Sharepoint OK -- at least, I don't get any exception when doing so -- but when I try to read a url from the site I get a 401 exception. What could be the problem?

I believe Sharepoint is using Kerberos.

public class sprss {

	public static LoginContext lc = null;
	
	public static void main(String[] args) {
	
		try {
			lc = new LoginContext("sprss", new sprsscallbackhandler());
		} catch (LoginException le) {
			System.err.println("Cannot create LoginContext. " + le.getMessage());
			System.exit(-1);
		} catch (SecurityException se) {
			System.err.println("Cannot create LoginContext. " + se.getMessage());
			System.exit(-1);
		} 

		try {
			lc.login();

		} catch (LoginException le) {

			System.err.println("Authentication failed:");
			System.err.println("  " + le.getMessage());
			System.exit(-1);
		}

		System.out.println("Authentication succeeded!"); // Good so far

		new sprssreader().go();
	}
}

public class sprssreader { 
      
     public void go() { 

          try { 
               /* hard coded */ 
               URL url = new URL("http://sharepoint.blahblah.com/sites/blahblah/listfeed.aspx?List={89EF9159-CB69-4992-87E3-4055164AC741}"); 

               SAXParserFactory spf = SAXParserFactory.newInstance(); 
               SAXParser sp = spf.newSAXParser(); 

               XMLReader xr = sp.getXMLReader();

               sprsshandler handler = new sprsshandler(); 
               xr.setContentHandler(handler); 
                
               xr.parse(new InputSource(url.openStream())); 
                
          } catch (Exception e) { 
		System.out.println(e);
          } 

     } 
}

Are the pertinent methods in sprsscallbackhandler ever called?

[Thomas Kennedy]

No they weren't. Any this is now fixed. There was something wrong with my url string, though I do not now remember what it was.

Also I stopped using LoginContext and went back to trying Authenticator alone -- that worked. I'm not so clear on the differences between the two.
