Hi All, Is it possible to use "<security-constraint>" for a standalone client, not a web client. What i want is: I will make a call to a html/jsp page which is defined inside Tomcat/web.xml's security-constraint. when i make a http call to these pages, i want to pop-up the username/password dialog ( security constraint dialog box), where the user can enter the username/password, which will be validated against the database (JDBC Realm). I know how to do the same for web-client, but i am not able to simulate the same for standalone client. When i hit to the jsp/html, using // Code :: String urlString = "http://localhost/test/view/test.html"; URL url = new URL(urlString); HttpURLConnection urlConn = (HttpURLConnection) url.openConnection(); it is showing the following Error : java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost/test/view/test.html , i thought i would popup the window??? why it is not showing the username/password window,??? where as it works if i give the same URL in the browser .... Any help would be highly appreciated.. Thanks in Advance,, ~Shridhar..
