Problem with h:dataTable and binding attribute

Question

I am new to JSF and I have a problem using the binding attribute of h:dataTable.
I can successfully use the value attribute to display rows of data fetched from an Oracle database into h:dataTable, but I do know how to bind a h:dataTable to a server object which I would use to update the changes made in the h:dataTable.
Can some body show me an example how to do so ?
Thanks in advance.

I'm not sure whether i understand your problem,
It doesnot need using the binding attribute If you wanna updating the value of each rows in the datatable.
below is a sample that updating each rows of a datatable
jsp file
<h:dataTable value="#[sampleBean.data}" var="row">
    <h:column><h:inputText value="#{row.col1}"/></h:column>
</h:dataTable>
<h:commandButton value="update" action="#{sampleBean.update}"/>BackingBean:
SampleBean.java
public class Samplebean{
  private SampleRow[] rows[];
  public SampleRow[] getData{
          return rows;
  public String update(){
      for(int i=0; i<rows.length; i++){
         rows.update();
return "success";
SampleRow.java
public class SampleRow{
  private String col1;
  public String getCol1(){
    return col1;
  public void setCol1(String col1){
    this.col1 = col1;
  public void update(){
     //write your code to save one row data to db/file here
