'struts2:getting value of multiple checkbox and made them checked on another page

I am working on struts2. I have 3 checkbox in my jsp page (say a.jsp) like 

<s:checkbox name="authority" fieldValue="ORIGINATOR"/>
<s:checkbox name="authority" fieldValue="EVALUATOR"/>
<s:checkbox name="authority" fieldValue="EXECUTOR"/>

Suppose I checked first two and when I fetched the value of “authority” in my action class in gives “ORIGINATOR, EVALUATOR”. Now in another jsp page (say b.jsp) I have all these checkbox as it is and I need those two checkbox should be checked here what I have checked in my previous jsp page (a.jsp).

Thanks in advance.

You can set the "value" property to "true" to make this check box checked. For example, you can write the code like this: < s:checkbox name="authority" fieldValue="ORIGINATOR" value="%{var}" > while the "var" is in the server side.

Well, this is an example:

the a.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <s:form action="Handler" method="post">
        <s:checkbox name="authority" fieldValue="ORIGINATOR" label="ORIGINATOR"/>
        <s:checkbox name="authority" fieldValue="EVALUATOR" label="EVALUATOR"/>
        <s:checkbox name="authority" fieldValue="EXECUTOR" label="EXECUTOR"/>
        <s:submit label="Submit"></s:submit>
    </s:form>
</body>
</html>

b.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <s:form>
        <s:checkbox name="authority" fieldValue="ORIGINATOR" value="%{isORIGINATORSet}" label="ORIGINATOR"/>
        <s:checkbox name="authority" fieldValue="EVALUATOR" value="%{isEVALUATORSet}" label="EVALUATOR"/>
        <s:checkbox name="authority" fieldValue="EXECUTOR" value="%{isEXECUTORSet}" label="EXECUTOR"/>
    </s:form>
</body>
</html>

The handler is:

package com.sesoft.test;

import com.opensymphony.xwork2.Action;

public class Handler implements Action{

    private String isORIGINATORSet = "false";
    
    private String isEVALUATORSet = "false";
    
    private String isEXECUTORSet = "false";
    
    private String[] authority;
    
    @Override
    public String execute() throws Exception {
    
        
        for(String s : authority){
            
            if(s.equals("ORIGINATOR"))
                isORIGINATORSet = "true";
            if(s.equals("EVALUATOR"))
                isEVALUATORSet = "true";
            if(s.equals("EXECUTOR"))
                isEXECUTORSet = "true";
        }
        
        return Action.SUCCESS;
    }

    public void setAuthority(String[] authority){
        
        this.authority = authority;
    }
    
    public String getIsORIGINATORSet(){
        
        return this.isORIGINATORSet;
    }
    
    public String getIsEVALUATORSet(){
        
        return this.isEVALUATORSet;
    }
    
    public String getIsEXECUTORSet(){
        
        return this.isEXECUTORSet;
    }
}

convert the comma separated string to String[] and set the string array as value to checkboxlist.
