The Tag and Drop Down Menu

[Caroline Jen <ji...@yahoo.com>]

To make it simple, there is a JavaBean.  This JavaBean
has two properties: label and value.  Because I have a
number of label and value pairs, I have a Collection
of this JavaBean(s).

To create a drop down menu, I do the following:

<bean:define id="GiveAnyName"
name="NameOfTheCollectionOfJavaBeans" scope="request"
type="java.util.ArrayList"  />

<html:select size="1" property="Property in the form
bean to hold the selection" multiple="false">
    <html:options
collection="NameOfTheCollectionOfJavaBeans"
property="value"
labelProperty="label"/>
</html:select>

How do I use the <c:...  > tag to do the same thing?

Something like this in JSP1.2:
assuming the Struts form bean is called 'formbean' and the property is 
called 'property'

<select size="1" name="property" multiple="false">
    <c:forEach items='${NameOfTheCollectionOfJavaBeans}' var='item'>
        <option value="<c:out value='${item.value}'>" <c:if test="${item.value==formbean.property}">selected</c:if>><c:out value='${item.label}'></option>
    </c:forEach>
</select>


or in JSP2.0:

<select size="1" name="property" multiple="false">
    <c:forEach items="${NameOfTheCollectionOfJavaBeans}" var="item">
        <option value="${item.value}" ${item.value==formbean.property ? "selected" : }>${item.label}</option>
    </c:forEach>
</select>
