Help with form bean [urgent]

[Rajat Pandit <ra...@centergroupinc.com>]

Ok, yet another attempt to explain my problem. Say I have a registration
form and I have the list of countries stored in an ArrayList with each
element as a key, value pair (Map). Now when I call the registration
form. The actionForm for the the registration form has one field country
(with both the getter and setter). How do I write the bean tag, so that
the ArrayList (which is placed in the request scope already) is taken to
render a dropdown menu of countries and the value of the selected item
goes into the countryId property of the registration ActionForm.

If ur still with me so far, then yet another question, how do do the
same in case I want to user to select the countries from a checkbox
(could be possibly multiple countries) if possible please give me a
sample code to learn as well.

My project deadline is coming close and I am stuck with conceptual
problems. Please consider this as urgent call for help.

Thanks in advance.

Rajat,

Greetings.  Just curious, what is your project for?  Are you doing work
for Motorola?

Take it easy!

If you've set the Map up in you Action, something like this:
    Map countries = new HashMap();
    countries.put("AF", "Afghanistan");
    countries.put("AL", "Albania");
    countries.put("DZ", "Algeria");
    countries.put("AS", "American Samoa");
    countries.put("AD", "Andorra");
    countries.put("AO", "Angola");
    countries.put("AI", "Anguilla");
    countries.put("AQ", "Antarctica");
    request.setAttribute("countries", countries);

You can generate the list in your JSP using:
  <html:select property="countryId">
  	<html:options collection="countries" property="key" labelProperty="value"
/>
  </html:select>

'countryId' is the name of the property in your ActionForm
'countries' is the request scope attribute name where you stored the Map.

You would probably want to load the list from a properties file or database
and since these values don't change very often, you could do this once at
startup and place the Map in application scope rather than in the request.

To generate checkboxes, use something like this:

  <logic:iterate name="countries" id="country">
    <html:multibox property="countryIds" name="countries">
      <bean:write name="country" property="key"/>
    </html:multibox>
    <bean:write name="country" property="value"/><br/>
  </logic:iterate>

Your form property must be a String array to receive multiple values.

p.s. Please don't put 'urgent' in your subject line. It may not achieve the
effects you desire ;-)
