curl and form submission

[Bob <bobnlinux@gmail.com>]

Hello list,

I'm trying to automate my internet login which is based on a web form. I 
have already checked few tutorial/posts on form submission by curl. I 
have tried various combinations too but nothing worked in my case.

When I inspect the form I get following for username/password text box 
and submit button

````````

<input type="text" name="Username" size="20">
<input type="password" name="Password" size="20">
<input type="submit" class="btn_cp" value="Login" onclick="return 
validateForm()">

```````

when I check by curl I get below


~~~~

# curl <link>/Login.jsp | grep Username

                                 Dload  Upload   Total   Spent Left  Speed

--:--:--     0function newCookie(Username,value,days) {
       document.cookie = Username+"="+value+expires+"; path=/"; }
    function readCookie(Username) {
       var nameSG = Username + "=";
    function eraseCookie(Username) {
      newCookie(Username,"",1); }
        newCookie('theName', document.login.Username.value); // add a 
new cookie as shown at left for every
       document.login.Username.value = '';   // add a line for every field
    document.login.Username.value = readCookie("theName");
    document.login.Username.value = trim(document.login.Username.value);
        if(document.login.Username.value.length==0){
             document.login.Username.focus();
    var uname = "?"+document.login.Username.value+"+/@";
                      <td width="35%" height="25" align="center" 
valign="middle" nowrap="nowrap"><strong 
style="color:#FFFFFF">Username&nbsp;</strong></td>
                      <td width="48%" align="left"><input type="text" 
name="Username" size="20" ></td>

# curl <link>/Login.jsp | grep Pass

    document.login.Password.value = readCookie("theEmail");
    if(document.login.Password.value.length==0){
         alert("Password is required.");
              document.login.Password.focus();
    var pwd = "?"+document.login.Password.value+"+/@";
    document.login.LoginPassword.value=encodeURIComponent(pwd);
                            <td height="26" align="center" 
valign="middle" nowrap="nowrap"><strong

^^^^^


Hence I construct a curl command like

curl -sd "Username=<username>&Password=<password>&submit=Login" 
http://<link>/Login.jsp

which is not working unfortunately. Have I missed anything ?

Your clue will be helpful.
