How to make an option selected from a dropdown list in jsp?

Question

In my project. I want to populate the drop down list on a jsp from a database.

<select id="names" name="names"> <c:forEach items="${names}" var="names">
        <option><c:out value="${names}"/></option>
    </c:forEach>
</select>

The ${names} is a list of names from the database. I want to select an option dynamically in the drop down list. Suppose there are three names in the database Rohan, Dean, Justin. If Dean is logged, i want select the option Dean as selected.

I try a code like this but this does not work.

<option value="${names}" ${names == names ? 'selected' : ''}>${names}</option>

You could post the code showing what have you tried. This is better than just asking how to do the things. — Luiggi Mendoza

Comparing strings should be done with equals() not with == — Nir Alfasi

First, you should change the name of that local names var to name, just for easier maintenance. Second, you're comparing names with names (and you should use equals to compare String variables), like 1 == 1, you should compare the name variable with a request or session parameter that handles the actual userName or another variable you want/need. — Luiggi Mendoza

Try like this assuming that loggedInUser variable holds the String value of the currently logged in user.

<select id="names" name="names">
<c:forEach items="${names}" var="names">

    <c:when test="${loggedInUser eq names}">    
        <option value ="<c:out value="${names}"/>" selected="selected">${names}</option>
    </c:when>
    <c:otherwise>
        <option><c:out value="${names}"/></option> 
    </c:otherwise>  
</c:forEach>

You should point that loggedInUser is a String request parameter as well and it is available at that moment.

Based in the OP posted code, it looks like he/she still has problems in that area.
