Hi,
I am trying to create a Java application that will connect to a URL, fill out the form and submit it.
How would I go about doing this?
Thanks in advance,

I'm doing something exceedingly similar, but I'm not sure how to get it to work, to be honest. Basically, I'm trying to download information from a site that requires a username and password. The html of the site is as follows, as well as my code. Any help would be appreciated!
<form method="post" action="/cards/FALLON19790309A.php">
<p>Username:   <input type="text" name="username" size="16" maxlength="16" value=></p>
<p>Password:   <input type="password" name="password" size="16" maxlength="16"></p>
<input type="hidden" name="action" value="muffinklezmer">
<input type="hidden" name="nocache" value="1046986423">
<input type="submit" value="Log in"></form>
My code right now looks like this:
URL playerCard = new URL("http://www.webpage.com");
URLConnection pcConnection= playerCard.openConnection();     
pcConnection.setRequestProperty("username","ABCDE");
pcConnection.setRequestProperty("password","12345");
BufferedReader in = new BufferedReader(
new InputStreamReader(
pcConnection.getInputStream()));
pcConnection.connect();
String inputLine = in.readLine();
while (inputLine != null)
System.out.println(inputLine);
inputLine = in.readLine();
}
