sorry
I removed method="getCities" , getting only empty select box

I removed the method="getlist" in struts.xml file but I m not getting any output of the select box...... getting only empty...

Hi, I try for populate of my array, but i end-up with below error .
I had few queries along with this issue : 1. How to pass parameters to method in struts.xml ?
2. Is that possible to populate the local variable at view which is return of the method, condition: the method should not be called on execute().


public class ListGen extends ActionSupport { private static List<Villages> maglist; static { maglist=new ArrayList<Villages> (); maglist.add(new Villages(1, "Atlanta")); maglist.add(new Villages(2, "Chicago")); maglist.add(new Villages(3, "Detroit")); } public List<Villages> getMaglist() { return maglist; } private int city; private int country; public City[] getCities() { City[] cities = null; cities = new City[3]; cities[0] = new City(1, "Atlanta"); cities[1] = new City(2, "Chicago"); cities[2] = new City(3, "Detroit"); return cities; } public int getCity() { return city; } public void setCity(int city){ this.city = city; } public int getCountry() { return country; } public void setCountry(int country) { this.country = country; } public String execute() throws Exception { return "success"; } } class City { private int id; private String name; public City(int id, String name) { this.id = id; this.name = name; } public int getId() { return id; } public void setld(int id) { this.id = id; } public String getName () { return name; } public void setName(String name) { this.name = name; } }

the Struts.xml
<action name="getlist" class="com.login.ListGen" method="getCities"> <result >/loginperson.jsp</result> </action>

the jsp
<s:select list="cities" listKey="id" listValue="name" name="Cities" label="Cities"></s:select> <s:submit/>

The error which i got
