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

Create an action class  as shown:  

iteratorTag.java

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.

iteratorTag.jsp
