Hello, every one:

In Tomcat ( above 4.1.xx ), I have configured The SSL connector on port 8443,
then I can access the url "https://192.168.0.27:8443/test.html" correctly in IE, 
But when runing the following code :

      URL  url = new URL( "https://192.168.0.27:8443/test.html" );
      url.openStream();
      
in a JSP file, the following Exception throwed, Who know why this happen and how to correct it?
