I have a problem and a question. First the problem. I get a
ClassCastException on the second line of the following fragment:

      URL url = new URL (args[0]);
      w3c.www.protocol.http.HttpURLConnection c =
         (w3c.www.protocol.http.HttpURLConnection) url.openConnection();

when run with the following command line:

  e:\jdk1.1.1\bin\java  -classpath

.;c:\jigsaw-alpha5\jigsaw\classes\jigsaw.zip;e:\jdk1.1.1\lib\classes.zip

      -Djava.handler.protol.pkgs=w3c.www.protocol httpURLTest
      http://www.microsoft.com

where httpURLTest is shown at the end of this message.

My question is: How do you get the status code of an HttpURLConnection
or a URLconnection?

Thanks in advance.

      int  cnt   = 0;
      while ((cnt = in.read(buf)) > 0)
         System.out.print(new String(buf, 0, 0, cnt));
      System.out.println("-");
      in.close();
 } catch (Exception ex) {
      ex.printStackTrace();
 }
 System.exit(1);
  }
