i am using this code in jsp to display the values.
when i select one row and click on button, i want to display that values in next jsp.
kindly give the idea how to get the selected value in java class.

You need a binding to the dataTable

<h:dataTable styleClass="dataTable" id="list" value="#{PostCodeBean.postCodeList}" var="plist" rows="10"
binding="#{PostCodeBean.postCodeTable}">

Java Code:
private UIData postCodeTable;
<- setter and getter for this variable ->

then you can access the selected row with:
Object selectedObject = (Object) postCodeTable.getRowData();

i used the following code to display the list of values using datatable. after that i want to select one row and click on ok then i want get that perticular row data in java class.
but i got javax.faces.el.EvaluationException: java.lang.IllegalArgumentException when i am trying to call getRowData methos from UIData object.

<h:dataTable styleClass="dataTable" id="list" value="#{PostCodeBean.postCodeList}" var="plist" rows="10"
binding="#{PostCodeBean.postCodeTable}">

and having the getter and setter methods of UIData type varialbe in PostCodeListBean

i wrote the follwing code in selectPostCode() method of PostCodeListBean class and when i click on ok buttom in jsp i am calling this methd.but i got java.lang.IllegalArgumentException

Object selectedObject = (Object) postCodeTable.getRowData();



Thanks

Have you defined the postCodeTable as HtmlDataTable? getRowData is a method on that...
Here's a sample that I happen to have which does this:

  private HtmlDataTable _dataTable;

  public void setDataTable(HtmlDataTable dataTable)
  {
    this._dataTable = dataTable;
  }

  public HtmlDataTable getDataTable()
  {
    return _dataTable;
  }


  public String editLinkAction()
  {
    /* pull out the currently selected contact */
    Contact editContact = (Contact)this.getDataTable().getRowData();
    FacesContext ctx = FacesContext.getCurrentInstance();
    ValueBinding binding = ctx.getApplication().createValueBinding("#{editContact}");
    binding.setValue(ctx,editContact);
    return "drilldown";
  }
(You can see the related stuff here if you are interested)

Hi, I folloewed your suggestions to select a row from h:datatable and manipulate the selected records at the back end bean. Unfortunately, the getRowData() or getRowInder(), is throwing an " javax.faces.el.EvaluationException: java.lang.IllegalArgumentException" error. I used the same code as given beow. I also tried to get only the getrowIndexx() and it is returning -1 Please let me know Thanks Aish
