Struts iterator not working

Despite finding many other such questions and spending a lot of time on them, I am unable to figure out what is going wrong with my iterator.

I have a list of objects, which I want to iterate and display various properties of each object in text fields. I have setup iterator like in the code below, but somehow no rows appear.

This is the jsp :

<s:form theme="simple" id="salaryDetails" name="salaryDetails">
    <table>
        <tr>
            <td>Name</td>
            <td>Basic</td>
            //etc//
        </tr>

        <s:iterator value="salaryDetail" var="salaries">
            <tr>
                <td><s:textfield name="emplName" value="%{employeeCode}"/></td>
                <td><s:textfield name="basic"    value="%{basic}"/></td>
            </tr>
        </s:iterator>
    </table>
</s:form>

The output of this form is just the row with the headings whereas I expect rows of text fields with some data pre - populated. The iterator does not seem to be working. I am sure that the list contains data because I am able to print it on the console in the action class.

Please advice!!

Its really urgent.

Thanks

There seems some issue with your action.either you have not defined public getter for you list or you are not using the Bean property properly. a quick run of your example is working fine for me here is the sample code

public classDemoAction extends ActionSupport{
 private List<SalaryDetail> salaryDetail;
 // getter ans setter for this

 public String execute() throws Exception{
   SalaryDetail detail=new SalaryDetail();
   detail.setName("a");
   salaryDetail=new ArrayList<SalaryDetail>();
   SalaryDetail detail1=new SalaryDetail();
   detail1.setName("a");
   salaryDetail.add(detail);
   salaryDetail.add(detail1);
   return SUCCESS;

 }

}

here is the jsp code

 <s:form theme="simple" id="salaryDetails" name="salaryDetails">
        <table>
        <tr>
            <td>Name</td>
            <td>Basic</td>
            //etc//
        </tr>

        <s:iterator value="salaryDetails">
            <tr>
                <td><s:textfield name="emplName" value="%{name}"/></td>

            </tr>
        </s:iterator>
    </table>

just cross check your code there is either some typo or might be inconstancy with naming
