I want to open a url and read it into a string.
That string will be passed onto a json parser.
I tried this.. but it's doing nothing...

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

function getURL(url) {
   URL hp = new URL(url);
   URLConnection yc = hp.openConnection();
   BufferedReader in = new BufferedReader(new
InputStreamReader(yc.getInputStream()));
   String inputLine;
   while ((inputLine = in.readLine()) != null)
   {
      alert(inputLine);
      in.close();
   }
}
