The block of code that triggered the error is shown below:


<tr class="row2">
<td width="37%" align="right" nowrap><Strong><font face='century gothic' >Country</font></td>
<td width="3%"></td>
<td width="60%">
<spring:bind path="contact.countryCode">
<select name="countryCode" class="select">
<option selected value="">(SELECT)${status.value}</option>
<c:forEach items="${countries}" var="county">
<option value="${county.COUNTRYCODE}" <c:if test="${status.value eq county}">selected</c:if>>${county.COUNTRYNAME}</option>
</c:forEach>
</select>
<font color="red">${status.errorMessage}</font>
</spring:bind>
</td>
</tr>

countries is a list of map objects while county is a reference variable to the map objects in the list.

are you sure there is filed named "COUNTRYCODE" in county, and there also should be the setter and getter.

[sundec19]

Below is the refenceData method of the controller.

protected Map referenceData(HttpServletRequest request) throws Exception {
Map model = new HashMap();
model.put("countries", listWriter.getCountries());
return model;
}

Also, below is the block of code that fetches contries data fron database.
Please help!!!

public List<Map> getCountries(){
String query = "select country_code as countryCode, upper(country_description) as countryName from country order by country_description";
return springDao.getResultMap(query);
}

Below is the springDao referenced above:

public List<Map> getResultMap(String query){

log.info(query);
List<Map> lst= new ArrayList<Map>();

try{

lst = (List<Map>)getJdbcTemplate().queryForList(query);

}catch(Exception exp){
log.fatal(exp);
}

return lst;
}

Make sure your servlet container is 2.4+ - as this could be down to you not being able to use the expression language.

Also, drop the spring bind tags if you're using spring 2.0+ and use the form taglibs.

Lastly check your spelling as "county" should be "country"

[sundec19]

I'm using Tomcat 5.5.17 which is a Servlet 2.4+ compliant container.

Using country as the variable didn't work as well.


I'm using spring 1.2.9. Please if this is not a version of Spring 2.0+, help me with sample code of form taglibs.

[Sprang]

do u have

version="2.4" in your web.xml and have you used the expression language in other pages on your site?

Regarding form taglib - u will need to upgrade your spring libs and then read http://static.springframework.org/sp...jsp-formtaglib
