    </form>
    <h1>&nbsp;</h1>
</body>
</html>

and second jsp as below

 <%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <input type="text" value="<%request.getParameter("TSI_Query_Box");%>">
        <input type="text" value="<%request.getParameter("SI_Query_Box");%>">
    </body>
</html>

Here i want to know how to retrieve the textarea values into the second jsp. i heard that i can use hidden values but not sure of how to use them. actually i want this data for submition in my database. please let me know how do i do it.

Thanks

first of all your function hide(x) must have two parameters as:

function hide(x,y)
{
    document.getElementById(x).style.display='none';
    document.getElementById(y).style.display='block';
}

and when you assign the value in JSP, you must use <%= %> instead of <% %>

so you must change your HTML to:

<input type="text" value="<%=request.getParameter("TSI_Query_Box")%>">

and also Take a look at the answer, How to avoid Java Code in JSP-Files?

At first change

<input type="text" value="<%request.getParameter("TSI_Query_Box");%>">

to

<input type="text" value="<%= request.getParameter("TSI_Query_Box"); %>">
