show the selected value in dropdown on edit jsp page on page load (Spring MVC)

I want to show the selected value in the dropdown on page load. My edit page shows a value, country. Now user belongs to USA, so USA should be selected by default on page load. I can use javascript or jquery.

I found few help on internet but they were with scriplets (<% %>) and I don't want to use them.

I am passing a List which has Id and Value. Also I have Id in another object. I can write the code by introducing a for loop in jsp and showing the value, but may be I am doing some mistake there. Also wanted to know if there is any better way to do this.

I am using Spring MVC.

Thanks.

"Now user belongs to USA, so USA should be selected by default on page load.". You know before hand user belongs to some country.

Assuming you have a pojo Country as:

    public class Country{ 
        String countryName;
        String countryId;
        //setters and getters
    }

    public class YourForm{
        List<Country> countryList;
        String selectedCountryId;
        ...
        //setters and getters
    }

In your controller method which delegates to the jsp:

    ...
    YourForm form = new YourForm();
    //set your countrylist to form 
    //set  country user belongs to - selectedCountryId - since you know before hand user belongs to some country.
    model.addAttribute("yourForm", form):
    ...

Now access it in jsp as:

    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
    </head>
    <body>
    <form:form id="yourForm" modelAttribute="yourForm" method="post">

    <tr>
        <td width="50%" class="label">
            <form:select id="countryId" path="selectedCountryId" title='Select Country'>
                <option value="">Please Select</option>
                <form:options items="${countryList}" itemValue="countryId" itemLabel="countryName"/>
            </form:select>
        </td>
    </tr>
    </body>

Since selectedCountryId is already set in controller you will see that country as auto selected in the jsp.
