I am very new to struts. I am creating a sample web application. Below is a JSP page that takes values from the user. "Passengers" refers to the number of rows i want to create and is available on the value stack from the previous action.
<s:form method="post" action="passengerDetailsEntered">
<tbody>
<s:iterator begin="0" end="passengers-1">
<tr>
<td><s:property value="top+1"/></td>
<td><s:textfield name="passengerDetails.name"></s:textfield></td>
<td><s:textfield name="passengerDetails.age"></s:textfield></td>
<td><s:select list="#{'M':'Male','F':'Female'}"
headerValue="Select" headerKey="-1"
name="passengerDetails.sex"></s:select>
</td>
</tr>
</s:iterator>
<s:hidden name="totalFare" value="%{totalFare}"/>
<s:submit value="Submit" id="select"></s:submit>
</tbody>
</s:form>
So if i want to add details of 3 passengers then value of passengers will be 3. It works fine upto here. Now what my anticipation is when i submit this form, then the iterator itself create a list containing two objects of type PassengerDetails, if value of passengers is 2. "passengerDetails" is an object of type PassengerDetails. Following is my PassengerDetails POJO.
package com.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
@Entity
@Table(name="passengerdetails")
public class PassengerDetails implements Serializable{
private static final long serialVersionUID = 4786387763215540175L;
private String name;
private int age;
private char sex;
private TicketDetails ticketDetails;
@Id
private int passengerid;
@Column(name="name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name="age")
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Column(name="sex")
public char getSex() {
return sex;
}
public void setSex(char sex) {
this.sex = sex;
}
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name="tid")
public TicketDetails getTicketDetails() {
return this.ticketDetails;
}
public void setTicketDetails(TicketDetails ticketDetails) {
this.ticketDetails = ticketDetails;
}
}
Following is my action class TicketBookingAction and the method passengerDetails of it is called when action "passengerDetailsEntered" is executed:
package com.view;
import java.text.ParseException;
import java.util.Calendar;
import java.util.List;
import java.util.Map;
import com.controller.FetchDetailsManager;
import com.controller.PassengerDetailsManager;
import com.controller.TicketDetailsManager;
import com.model.PassengerDetails;
import com.model.ScheduleDetails;
import com.model.TicketDetails;
import com.model.UserDetails;
import com.opensymphony.xwork2.ActionContext;
public class TicketBookingAction{
private List<PassengerDetails> passengerDetails;
public List<PassengerDetails> getPassengerDetails() {
return passengerDetails;
}
public void setPassengerDetails(List<PassengerDetails> passengerDetails) {
this.passengerDetails=passengerDetails;
}
public String passengerDetails()
{
System.out.println("Name is");
System.out.println(getPassengerDetails().get(0).getName());
System.out.println(getPassengerDetails().get(0).getAge());
System.out.println(getPassengerDetails().get(0).getSex());
System.out.println(getPassengerDetails().get(1).getName());
System.out.println(getPassengerDetails().get(1).getAge());
System.out.println(getPassengerDetails().get(1).getSex());
return "passengerDetailsFilled";
}
}
But it prints the name as null. Age is printed as entered by the user. Sex is printed as some junk character. Can anyone please help me with the concept that lies behind this? And what should i do to get all the values entered by me on the form in my action class. Thanks in advance.
