Dear dudes,
I'm facing a problem in displaying or re-rendering my form data which i sent to the controller , whose values are set to my formbean and sent to the action class.
My request page : submit.jsp
form bean : SubmitForm.java
Action class: SubmitAction.java

View page: "submit.jsp"

<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
 
<html>
<head><title>Submit example</title></head>
<body>
 
<h3>Example Submit Page</h3>
 
<html:errors/>
 
<html:form action="submit.do">
Last Name: <html:text property="lastName"/><br>

Sex:       <html:radio property="sex" value="M"/>Male 
           <html:radio property="sex" value="F"/>Female<br>

My form bean:"SubmitForm.java"

package hansen.playground;
 
import javax.servlet.http.HttpServletRequest;
 
import org.apache.struts.action.*;
 
public final class SubmitForm extends ActionForm {
 
  /**

private static final long serialVersionUID = 1L;
/* Last Name */
  private String lastName = "Hansen"; // default value
  public String getLastName() {
    return (this.lastName);
  }
  public void setLastName(String lastName) {
    this.lastName = lastName;
  }
 
  /* Address */
  private String address = null;

    return (this.address);
  }

    this.address = address;

  public void setSex(String sex) {
    this.sex = sex;
  }
 
  /* Married status */
  private String married = null;
  public String getMarried() {
    return (this.married);
  }
  public void setMarried(String married) {
    this.married = married;
  }
 
  /* Age */
  private String age = null;
  public String getAge() {
    return (this.age);
  }
  public void setAge(String age) {
    this.age = age;
  }
  
  public ActionErrors validate(ActionMapping mapping,
         HttpServletRequest request) {
  // Log the forms data
  servlet.log("Lastname:" + lastName);       
  servlet.log("Address:" + address);       
  servlet.log("Sex:" + sex);       
  servlet.log("Married:" + married);       
  servlet.log("Age:" + age);
  
  // Check for mandatory data
  ActionErrors errors = new ActionErrors();
  if (lastName == null || lastName.equals("")) { 
    errors.add("Last Name", new ActionError("error.lastName"));
  }
  if (address == null || address.equals("")) { 
    errors.add("Address", new ActionError("error.address"));
  }
  if (sex == null || sex.equals("")) { 
    errors.add("Sex", new ActionError("error.sex"));
  }
  if (age == null || age.equals("")) { 
    errors.add("Age", new ActionError("error.age"));
  }
  return errors;
}
 
  
 
}

Once when my struts-config.xml is loaded from my web.xml , the formbean is initialized and the 'lastname' value is initially set as Hansen, which i got when i run my application.
Once when i render data for other controls in my form and submit i'm not getting any data, server console is devoid of any errors and the log file ( localhost ) is showing:

Why the form is not being re-rendered again eventhough i've mapped it in my struts-config file.
Any help in this regard will be appreciated.

Rgds.
