Struts2: get the value of multiple checkboxes and validate them on another page
I am working on struts2. I have 3 checkboxes 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 the first two, and when I get the "authority" value in my action class, it returns "ORIGINATOR, EVALUATOR". Now in another jsp page (say b.jsp) I have all these checkboxes as they are, and I need these two checkboxes to be checked here, which I checked in my previous jsp page (a.jsp).
Thanks in advance.

You can set the value property to "true" for this checkbox to be checked. Got it? For example, you can write code like this: <s: checkbox name = "authority" fieldValue = "ORIGINATOR" value = "% {var}"> while "var" is on the server side.
Well this is an example:
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>
Handler:
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;
}
}
