how to make a option selected in <s:select>

[Pradeep Chaubey]

HI Experts,
I am facing a problem to make a option selected in <s:select> when page get render.
I am using following codes:
In Action Class

 
 private List<ClientTypeModel> clientTypeList;
 private String clientType;
 private String selectedClient;

I have getter and setter of the all properties declared above.
ClientTypeModel is a bean, details as follows :

   
  public class ClientTypeModel implements Serializable{
        private String clientTypeId;
	private String clientTypeDesc;

       public String getClientTypeId() {
		return clientTypeId;
	}

	public void setClientTypeId(String clientTypeId) {
		this.clientTypeId = clientTypeId;
	}

        public String getClientTypeDesc() {
		return clientTypeDesc;
	}

	public void setClientTypeDesc(String clientTypeDesc) {
		this.clientTypeDesc = clientTypeDesc;
	}
  }
 

In Jsp I am using following code :

   
    <s:select cssStyle="width:146px;" list="clientTypeList" name="clientType" listKey="clientTypeId" 
	listValue="clientTypeDesc" emptyOption="false" label="Client Type" value="selectedClient"></s:select>
 

When page get rendered, every time first option get Selectd by default, Even if I assign the last option value of the list
to variable "selectedClient" in the action class.

Please help me to sort out this problem.
