    Hi, 

     

    You'll need a Visualforce page with an Apex controller that calls your GlobalWhetherClass — using a <apex:actionSupport> to re-render the cities list when country changes.  

     

    public class WeatherController {
        public String selectedCountry { get; set; }
        public String citiesResult { get; set; }
        public List<SelectOption> getCountries() {
            return new List<SelectOption>{
                new SelectOption('India', 'India'),
                new SelectOption('United States', 'United States'),
                new SelectOption('United Kingdom', 'United Kingdom')
                // Add more as needed
            };
        }
        public void fetchCities() {
            if (String.isNotBlank(selectedCountry)) {
                GlobalWhetherClass.GlobalWeatherSoap svc = new GlobalWhetherClass.GlobalWeatherSoap();
                citiesResult = svc.GetCitiesByCountry(selectedCountry);
            }
        }
    }

     

    <apex:page controller="WeatherController">
        <apex:form>
            <apex:pageBlock title="Weather Lookup">
                <apex:pageBlockSection>
                    <apex:selectList value="{!selectedCountry}" size="1">
                        <apex:selectOptions value="{!countries}"/>
                        <apex:actionSupport event="onchange"
                                            action="{!fetchCities}"
                                            reRender="citiesBlock"/>
                    </apex:selectList>
                </apex:pageBlockSection>
                <apex:pageBlockSection id="citiesBlock">
                    <apex:outputText value="{!citiesResult}" escape="false"/>
                </apex:pageBlockSection>
            </apex:pageBlock>
        </apex:form>
    </apex:page>

     

     

    • User selects a country from the dropdown
    • onchange fires fetchCities() via actionSupport
    • Controller calls GetCitiesByCountry on your SOAP class
    • Result re-renders in citiesBlock without a full page refresh

     

    Make sure

    http://www.webservicex.com is added to your Remote Site Settings

    (Setup → Remote Site Settings) — otherwise the callout will be blocked. 

      

    Hope this helps!
