hello everyone.
i am trying to write a program which will open a url connection to a website and to its form and fill it up with dat and then submitting this form.
when i run the program i know the fields name and what they are called in the scrip. know that it doesn't matter which scriptting language the webpage is using. But, if you needed to know it is javascript.
my question is if someone could help me a little here. i am reading some books here and there what i need is some tips or advice from those who wrote a similer program.

It sounds like you are trying to programmaticall y POST. The Jakarta Commons HTTPClient can help.
thanks i forgot to include that it will be done by using the POST command not by the GET command

Please note: If a user presses the submit-button then exactly that happens: the system sends a POST or GET request. (I know that here are also some other exotic ways and browsers, but I speak of the common case). So your question is like saying I want to make a fried egg, but I don't want to use a raw egg and I don't want to use a pan for that which would be the simplest way. So literally speaking, your only option then is to get a cook that does it for you.
How to get a cook:
Just use a Windows macro recorder (like Easy Macro Recorder or so) and start it. Then open your explorer, go to the page, fill out the values, press submit and then stop the recorder. It produces a file which you can then easily execute in your java program with Runtime.exec().
But if you want to fry your eggs yourself, which I would prefer, here is the source code of a program that sends a POST-request and gets the response page back (the HTML source code is contained in the return string). Then you can parse that string for any result you are interested in. It is quite old and uses a non-blocking HTTPClient.jar-file for the request, but you can also do it in a similar way with the java.net.URL class which are include in the newer java versions.
For example you are on google-site, enter "easy makro recorder" and press "submit". Then the browser send a request like that:
"http://www.google.com/search?q=easy+m akro+recorder".
Now the java program that does it for you: - import HTTPClient.HTTPConnection;
-
import HTTPClient.HTTPResponse;
-
import HTTPClient.CookieModule;
-
-
String urlWithValues = "search?q="+ URLEncoder.encode("easy makro recorder");
-
String host = "64.233.167.99"; // = google.com. You can also use InetAddress.getByName("google.com") instead.
-
String port = "80";
-
HTTPConnection connection = new HTTPConnection(host, port);
-
HTTPResponse response = connection.Post(urlWithValues);
-
-
InputStream input = response.getInputStream();
-
BufferedReader dataInput = new BufferedReader(new InputStreamReader(input));
-
String searchResults = "";
-
while (true)
-
{
-
String line = dataInput.readLine();
-
if (line == null) break;// end of response
-
searchResults += line;
-
}
-
-
System.out.println("google found following results:" + searchResults);

HI All,
I am writing a multi page form. I am using hidden input statements to
pass my variables between different pages. Now I want to provide a page
whereusers can update the previous entered data. The form at this point
is populated through the hidden variables.
But as I submit after making any changes.
the hidden values instad of updating get an extra value.
Is there any way to get around it.
Thanks

Have a lot of data to collect / choices presented, producing a large

Could some one say how best to create such a multi-page form. Submitted

necessary to identify each page as originating from the same user
