"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Could you be more specific?

Do you mean the contents of a file, an HTTP page or an image (gif or jpeg)

If http, do you just want straight text or do you want to simulate browser behaviour?

For instance, to read the contents of a file:

1.- Define the address (getCodeBase() uses the directory where the applet was loaded from as root)

String url = "http://" + getCodeBase().getHost() + "/file.dat";

2.- Define an Input (or output) stream and a buffer for the data . For instance:
             

DataInputStream data;
String line;
              
Instantiate a URL member and asign it to whatever type of I/O operation you need. Example:

try{
   try{
     URL theURL = new URL("http", getCodeBase().getHost(), 80, "/rooms.dat");
      data = new DataInputStream(new BufferedInputStream( theURL.openStream()));
       while ((line = data.readLine()) != null) {
           // do whatever you want with the info
           YourTexttArea.appendText(line); //(append without Text for 1.1)
   }                          }
   }catch( MalformedURLException e ) {
   // Do what you want with wrong address error here
                    }
}catch (IOException e) {
// Hande I/O error here.                    
}

Other types of files/behaviour will require additional work.

I mean loading a HTML page.  Like if you clicked on a regular link.

You can load the HTML page with showDocument() method. To load a HTML page into a specific frame you must give the name of the frame as a parameter. Here is a small example:

getAppletContext.showDocument(new   URL(getCodeBase()+"my_page.html",target);

target is a string which contains the name of the frame or window into which you want my_page.html to be loaded into.
