Struts2 - Radio Tag (Form Tags)

In this section, we are going to describe the radio tag. The radio tag is a UI tag that renders a radio button input field.
Add the following code snippet into the struts.xml file.

struts.xml
<action name="radioTag" class="net.struts2.checkboxlistTag">
  <result>/pages/uiTags/radioTag.jsp</result>
</action>

Create an action class with two lists as shown below:

checkboxlistTag.java

package net.struts2;
import com.opensymphony.xwork2.ActionSupport;
import java.util.*;

public class checkboxlistTag extends ActionSupport{
  
  private List fruits;
  private List animals;  
  public String execute()throws Exception{
  fruits = new ArrayList();
  fruits.add("Apple");
  fruits.add("Mango");
  fruits.add("Orange");
  fruits.add("Pine Apple");

  animals = new ArrayList();
  animals.add("Dog");
  animals.add("Elephant");
  animals.add("Ox");
  animals.add("Fox");
  return SUCCESS;

  }

  public List getFruits(){
  return fruits;
  }

  public List getAnimals(){
  return animals;
  }
}


Create a jsp using the tag <s:radio>.It renders a radio button input field.

radioTag.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
  <head>
  <title>Radio Tag Example!</title> 
 <link href="<s:url value="/css/main.css"/>" 
rel="stylesheet" type="text/css"/>  
  </head>
  <body>
<h1><span style="background-color: #FFFFcc">Radio Tag Example!
</span></h1>
<s:form>
 <s:radio label="Fruits" name="fruitsname" list="fruits"/>
 <s:radio label="Animals" name="animalsname" list="animals"/>
 </s:form>
