[Bug java/19066] New: the URL and URLConnection class should be enhanced

[zhsoft88 at sohu dot com]

1. create B.java:

import java.io.*;
import java.net.*;

public class B {
  public static void main(String[] args) {
  URL javacodingURL = null;
   try {
      javacodingURL = new URL(args[0]);
      System.out.println("protocol = " + javacodingURL.getProtocol());
      System.out.println("host = " + javacodingURL.getHost());
      System.out.println("filename = " + javacodingURL.getFile());
      System.out.println("port = " + javacodingURL.getPort());
  }catch(MalformedURLException e){
      // Malformed URL
      System.out.println("Error in given URL");
      return;
  }
    
  try {
      URLConnection connection = javacodingURL.openConnection();
      System.out.println("conn="+connection);
      System.out.println(connection.getContentType());
      BufferedReader br = new BufferedReader(new
InputStreamReader(connection.getInputStream()));
      String line = "";
      while ((line = br.readLine()) != null)
            System.out.println(line);
      br.close();
  }catch(UnknownHostException e){
      System.out.println("Unknown Host");
      return;
  }catch(IOException e){
      System.out.println("Error in opening URLConnection, Reading or Writing");
      return;
  }
 }     
} 

2. Compile it:

gcj -fjni --main=B B.java

3. Run it:

./a.out http://www.opendesktop.net

The output is:

protocol = http
host = www.opendesktop.net
filename =
port = -1
conn=gnu.gcj.protocol.http.Connection:http://www.opendesktop.net
null
Error in opening URLConnection, Reading or Writing

Error happened. But, if you compile B.java with javac, then run

java B http://www.opendesktop.net

The output is OK, no error happened.

And I also found that when you run like this:

./a.out http://www.opendesktop.net/

The output is also OK.

I think the URL and URLConnection class should be enhanced .
