How do i retain the selected value of a dropdown in a JSP?

This is my code of JSP :

<%if (session.getAttribute("user").toString().equalsIgnoreCase("Chhattisgarh")){ %>
    <select name="district" id="district" onchange="this.form.submit()">
        <c:forEach var="row" items="${result.rows}">
            <option value="${row.UserDispName_Eng}">${row.UserDispName_Eng}</option>
        </c:forEach>
    </select>
<%} else{
    out.println(session.getAttribute("user"));
} %>

i need to load another dropdown depending upon the selection made in this dropdown. i saw a post similar to it, but it didn't worked for me. How to keep Dropdownlist value same after refresh the page

what should i do to achieve this.

Save the option value selected in session and compare after for example:

if(session.getAttribute("user_dispname").equals("${row.UserDispName_Eng}")){

 selected = "selected=\"selected\"";

 }else{

 selected = "";
}

<option ${selected} value="${row.UserDispName_Eng}">${row.UserDispName_Eng}</option>

You can do one thing. on selection of any option call one java script function created by you.Write a code to create a new drop down html into it and set condition in that which set the right option as per your selection of first option.

onchange="callAnotherDropDown();"

Javascript

function callAnotherDropDown(){
   html code.
   creation of new drop down.
   condition to select the proper value.
}
