dwr.util.addOptions problem to show drop down menu please help

 

 

i have this class that i want to get cities for each country  here the code:

public class TestDWR {

    public ArrayList getCities(String value){
      ArrayList countriesList=new ArrayList(); 
      if(value.equals("1")){
          countriesList.add("Amman");
            countriesList.add("Jerash");
      }else if(value.equals("2")){
           countriesList.add("Jerusalem");
            countriesList.add("Haifa");
      }else if(value.equals("3")){
             countriesList.add("Macca");
            countriesList.add("Madina");
      }
      return countriesList;
    }

}

 

it works perfectly when i  test it through:

but i dont know how to see it work in my jsp  my last trial like this:

    function viewCities(value){
            //    alert("value="+value);
         
                 dwr.util.addOptions("citiesReply",TestDWR.getCities(value));
          }

 

where citiesReply is the name of drop down list.
