Add the following code snippet into the struts.xml file.
struts.xml
<action name="iteratorTag" class="net.struts2.iteratorTag"> <result>/pages/genericTags/iteratorTag.jsp</result> </action>
Create an action class as shown:
iteratorTag.java
package net.struts2;
import com.opensymphony.xwork2.ActionSupport;
import java.util.*;
public class iteratorTag extends ActionSupport{
private List myList;
public String execute()throws Exception{
myList = new ArrayList();
myList.add("Fruits");
myList.add("Apple");
myList.add("Mango");
myList.add("Orange");
myList.add("Pine Apple");
return SUCCESS;
}
public List getMyList(){
return myList;
}
}
