How to set selected value in html:options that isusing HasMap Long,String

Question

So here is my problem
I have a HashMap<Long,String> where key is the country id and value is the country name. So I am displaying it in the jsp using the below code
<c-rt:set var="countriesMap" value="<%=countriesMap%>" target="java.util.HashMap<Long,String>"/>
<html:select size="1" property="countryId" >
<html:option value="" />
<html:options collection="countriesMap" property="key" labelProperty="value" />
</html:select>
And my Action form has the property countryId.
So it works fine , it displays all the countries and sets the country ID in the form's property that we set in the property attribute of <html:select>.The form's property is of type Long.
But suppose if some error occurs in the validate method for some other property then when the page renders back it does not set the selected country in the list box.
Can anyone please help me out of this.Thanks in advance.

Hi,
I had the same issue. Altho I am using Spring, the solution is the same.
<select name="expMonth">
     <option value=""></option>
     <c:forEach items="${form.data.months}"
          var="month">
          <c:choose>
               <c:when test="${form.data.pDet.expDate_month eq month}">
                    <option selected="selected"><c:out value="${month}"/></option>
               </c:when>
               <c:otherwise>
                    <option><c:out value="${month}"/></option>
               </c:otherwise>
          </c:choose>
     </c:forEach>
</select>Disclaimer: Not sure if this is the correct way to do it, but it works for me
