How to display in JSP a list obtained from Hibernate query

I am creating an struts hibernate application. I have obtained a list using hibernate query and passed it in action class. But I don’t know how to display it in JSP.

I have successfully getting the list on the basis of query. Now I want to display this list in JSP.

I have posted struts.xml and the JSP for showing result also. Kindly check. But in JSP nothing is showing up. I am using s:iterate to show the list. But no luck. Even I have tried printing simple text under s:iterate, just for testing. But it is also not showing up.

POJO class:

package org.sachin.Model;

import java.sql.Date;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Temporal;

@Entity
@Table(name="feed")
public class FeedBack {

private FeedBack feedback;
 private int taste;
 private int waiter;
 private int infra;
 private int price;

 private int id;

 private Date date=new java.sql.Date(new java.util.Date().getTime());
public int getTaste() {
    return taste;
}
public void setTaste(int taste) {
    this.taste = taste;
}
public int getWaiter() {
    return waiter;
}
public void setWaiter(int waiter) {
    this.waiter = waiter;
}
public int getInfra() {
    return infra;
}
public void setInfra(int infra) {
    this.infra = infra;
}
public int getPrice() {
    return price;
}
public void setPrice(int price) {
    this.price = price;
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}


@Temporal(javax.persistence.TemporalType.DATE)
public Date getDate() {
    return date;
}
public void setDate(Date date) {
    this.date = date;
}
public FeedBack getFeedback() {
    return feedback;
}
public void setFeedback(FeedBack feedback) {
    this.feedback = feedback;
}


}

Action Class:

package org.sachin.action;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.sachin.Model.Datepicker;
import org.sachin.Model.FeedBack;
import org.sachin.hibernate.DateSpecific;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class SelectDateAction extends ActionSupport {

    /**
     * 
     */
private static final long serialVersionUID = -8922465133057293868L;
private Datepicker datepicker;
private List<FeedBack> list =new ArrayList<>();;

    public List<FeedBack> getList() {
    return list;
}
public void setList(List<FeedBack> list) {
    this.list = list;
}
    public String execute(){

        String date=getDatepicker().getDate1();


        DateSpecific da=new DateSpecific();

         list=da.find(date);
         for(FeedBack feed:list){
             System.out.println("price");
             System.out.println(feed.getPrice());


         }

        System.out.println("hi"+date);

        return SUCCESS;
    }


    public Datepicker getDatepicker() {
        return datepicker;
    }
    public void setDatepicker(Datepicker datepicker) {
        this.datepicker = datepicker;
    }

}

Hibernate class:

public List<FeedBack> find(String Date) {


                //  Transaction t=session.beginTransaction(); 

            String SQL_QUERY = " from FeedBack where date='"+Date+"'";
            System.out.println("i am in hiber");
            System.out.println(SQL_QUERY);
            org.hibernate.Query query = session.createQuery(SQL_QUERY);
            List<FeedBack> list = query.list();
          for(FeedBack f:list){
              System.out.println("price");
              System.out.println(f.getPrice());
          }
            return list;

        }

This is my struts.xml in which all actions are defined.For now the action is ByDate.

struts.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

        <action name="add" class="org.sachin.action.EditAdminAction"
            method="execute">
            <result name="success">/JSP/success.jsp</result>
            <result name="error">/JSP/AdminUserNameExists.jsp</result>

        </action>

    </package>

     <package name="serve" namespace="/tut" extends="struts-default">

        <action name="ByDate" class="org.sachin.action.SelectDateAction"
            method="execute">
            <result name="success" type="redirect">/JSP/iterate.jsp</result>
            <result name="error" type="redirect">/JSP/FeedBack.jsp</result>
            <result name="input" type="redirect">/JSP/Rateus.jsp</result>

        </action>
    </package>


</struts>

This is my JSP for showing list

iterate.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<s:form>
<body>
 <h1>Struts 2 Iterator tag example</h1>

<h3>Simple Iterator</h3>
<ol>
<s:iterator value="list">
 HE<li><s:property /></li>
</s:iterator>
</ol>
  </body>
  </s:form>
  </html>

I have successfully getting the list on the basis of query. Now I want to display this list in JSP.

Answer

Use iterator tag:

Iterator will iterate over a value. An iterable value can be any of: java.util.Collection, java.util.Iterator, java.util.Enumeration, java.util.Map, or an array.

The code:

<s:iterator value="list"/>
  Price: <s:property value="price"/><br>
</s:iterator>
