Error in JSF - java.lang.NumberFormatException: For input string:

Question

Nice day friends,
I am sure that this is one stupid question by newbie like me, but I already lost hope since there no many post on this error especially in JSF at Google.
Here the full error I've got :
executePhase(RENDER_RESPONSE 6,com.sun.faces.context.FacesContextImpl@12bb287) threw exception
java.lang.NumberFormatException: For input string: "id"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:447)
at java.lang.Integer.parseInt(Integer.java:497)
at javax.el.ListELResolver.toInteger(ListELResolver.java:373)
at javax.el.ListELResolver.getValue(ListELResolver.java:167)
Here my snippet of code :
NationalityDO.java (managed bean)
public class NationalityDO implements Serializable {
@Id
@Column(name = "ID", nullable = false)
private String id;
private List nationalityList;
public NationalityDO() {
public NationalityDO(String id) {
this.id = id;
public String getId() {
return this.id;
public void setId(String id) {
this.id = id;
public List getNationalityList(){
NationalityDA da=new NationalityDA();
if(nationalityList==null){
System.out.println("if(nationalityList==null)");
try {
nationalityList=da.retrieveNationalityList();
} catch (Exception ex) {
ex.printStackTrace();
return nationalityList;
public void setNationalityList(){
this.nationalityList=nationalityList;
This is my NationalityDA (used to retrieve data)
public class NationalityDA {
public NationalityDA() {
public List retrieveNationalityList() throws Exception{
ArrayList ls=new ArrayList();
Connection con = null;
PreparedStatement ps = null;
ResultSet rsReturn = null;
try {
con = DBManager.getDBConnection();
String sql="select id,descr,setup_date,change_date from nationality order by id asc" ;
ps = con.prepareStatement(sql);
rsReturn = ps.executeQuery();
while(rsReturn.next()){
List lsNationality =new ArrayList();
lsNationality.add(rsReturn.getString(1));//id
lsNationality.add(rsReturn.getString(2));//descr
ls.add(lsNationality);
} catch(SQLException sqlex) {
sqlex.printStackTrace();
} finally {
con.close();
ps.close();
return ls;
Here my nationality.jsp
<h:dataTable value='#{nationality.nationalityList}' var='item' border="1" cellpadding="2" cellspacing="0">
<h:column>
<f:facet name="header">
<h:outputText value="Id"/>
</f:facet>
<h:outputText value="#{item.id}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Descr"/>
</f:facet>
<h:outputText value="#{item.descr}"/>
</h:column>
</h:dataTable>
Here my face-config.xml
<managed-bean>
<managed-bean-name>nationality</managed-bean-name>
<managed-bean-class>com.dataobject.nationality.NationalityDO</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>

For your information, the retrieve of data work successfully, this is the table description in oracle database which is varchar for id,
SQL> desc nationality
Name Null? Type
ID NOT NULL VARCHAR2(4)
DESCR VARCHAR2(20)
SETUP_DATE TIMESTAMP(6)
CHANGE_DATE TIMESTAMP(6)

thanks....
Actually I already view the site many times before but after you told me then I get the idea,that's y working together is better, because i sometimes won't realize my mistake even it was the easiest one...
So i just change my code in NationalityDA.java as
while(rsReturn.next()){
NationalityDO n=new NationalityDO();
n.setId(rsReturn.getString(1));
System.out.println("rsReturn.getString(1)"+ rsReturn.getString(1));
n.setDescr(rsReturn.getString(2));
System.out.println("rsReturn.getString(2)"+ rsReturn.getString(2));
n.setSetupDate(rsReturn.getDate(3));
System.out.println("rsReturn.getString(3)"+ rsReturn.getString(3));
n.setChangeDate(rsReturn.getDate(4));
System.out.println("rsReturn.getString(4)"+ rsReturn.getString(4));
ls.add(n);
Once again, thanks..and my 3 dukes are yours..
