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);" >

Why dont you try redirecting from you java class, like this

actionResponse.sendRedirect("CallService.jsp");

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

<input type="submit" value="Submit" onclick="sample(this);" >

You cannot submit and redirect this.

In your servlet / jsp where the form is submitted, redirect the page.

Try this:

window.location.href = "CallService.jsp?username="+uname;

You are submitting form and redirecting to another form same time. It's not right

Your 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()">
