Iterator Tag
In this section, we are going to describe the Iterator tag. Iterator tag is used to iterate over a value. An iterable value can be either of: java.util.Collection, java.util.Iterator.
Add the following code snippet into the struts.xml file.
struts.xml
<action name="iteratorTag" class="net.roseindia.iteratorTag">
<result>/pages/genericTags/iteratorTag.jsp</result>
</action> |
Create an action class as shown:
iteratorTag.java
package net.roseindia;
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;
}
} |
The following example retrieves the value of the getMyList() method of the current object on the value stack and uses it to iterate over. The <s:property/> tag prints out the current value of the iterator.
