Reset to default 2Your button type is
<input type="submit" value="Submit" onclick="sample(this);" >
replace it with:
<input type="button" value="Submit" onclick="sample(this);" >
or
Call your function when submitting form like this:
<form method="post" name="fromname" onsubmit="yourfunction()">
Try this:
window.location.href = "CallService.jsp?username="+uname;

You cannot submit and redirect this.
In your servlet / jsp where the form is submitted, redirect the page.
please try:
function sample()
{
var uname = document.getElementById("uname").value;
//var pwd = document.getElementById("pwd").value;
window.location.href("CallService.jsp?username="+uname);
//FUNCTION MUST RETURN FALSE!!
return false;
}
<input type="submit" value="Submit" onclick="return sample(this);" >
this way js function will need to be evaluted before making postback
Why dont you try redirecting from you java class, like this
actionResponse.sendRedirect("CallService.jsp");
Since you are fetching the data using javascript here :
var uname = document.getElementById("uname").value;
theres no need to use a 'submit' button. Try to change
<input type="submit" value="Submit" onclick="sample(this);" >
into
<input type="button" value="Submit" onclick="sample(this);" >
