I want to write a Java application that collects information on  the client and then logs onto a web page and navigates it.
For example; automatically entering USERNAME then PASSWORD then selecting a link then entering more info etc...

The web page I want to navigate is based around Javascript forms, if it is possible:-

1) how do I enter information
2) how do I select links

I alredy know how to get the net connection and Http connections

Thanks in advance

 You can use the following workflow:
1. Enter the information using the normal awt components such as TextArea and TextField. Place them in card layouts. This setting would be the applet and you will place it in a top frame.
2. This applet will invoke html pages in another frame (say, the bottom frame) according to the data entered in the applet.

Would that do for your program? Or do you want to navigate an existing site according to the data that was submitted in that site's formes?
If you want more details / samples, feel free to ask.

Regards, G.

Q still on?

  OK, collect the data, as said, by a TextField for example, then u have three ways of sending it:
  1. CGI - create a CGI and encode the recieved data in to a URL
   (www.x.org/cgi-bin/enter?Pass=xyz&user=me) for example, then use java to request
   this document by HTTP and then u'l get what the CGI asnwered (correct? No?)
  2. Open a custom socket to the server, on which u must run a daemon of your own,
   which will process the login data and reply and all in you'r own format. This will also
   allow encryption
  3. Use standard HTTP authentication, will allow encryption, similar to CGI only this
   is better as it prevents browsing the site unless u correctly logged in.
 
  * U can also use HTTP or CGI authentification BEFORE the Java even loads.

   Now, to ask a frame to navige, u need to call the following command:
 
getAppletContext().showDocument(new URL(getCodeBase(),"whatever.html"), "framename");

  If u need MORE info don't reject the answer just leave a comment and I'l respond.
