GeneratorTag.java

package net.javajazzup;
import

import
org.apache.struts2.util.IteratorGenerator.Converter;
public class GeneratorTag extends
ActionSupport {
public String excute() throws Exception{
returnSUCCESS;
}
}

Create a jsp page where the generator tag <s:generator> generates a simple iterator based on the val attribute supplied and <s:iterator> tag prints it out using the
<s:property /> tag. The separator attribute is used to separate the val into entries of the iterator.

GeneratorTag.jsp

<%@ taglib prefix=”s” uri=”/struts-tags” %>
<html>
<head>
<title> Generator Tag Example </title>
</head>
<body>
<h2>Generator Tag Example</h2>
<h3>Generates a Simple Iterator</h3>
<s:generator
val=”%{‘JAVA,HTML,CSS,AJAX,JAVA

<s:iterator>

6. Generator Tag (Control Tags) Using
Count Attributes

In this section, we are going to describe the generator tag using the count attribute.

GeneratorTag.java

package net.javajazzup;
import
com.opensymphony.xwork2.ActionSupport;
import
org.apache.struts2.util.IteratorGenerator.Converter;
public class GeneratorTag extends
ActionSupport {
public String excute() throws Exception{
returnSUCCESS;
}
}

Create a jsp page where the generator tag <s:generator> generates an iterator with “count” attribute and <s:iterator> tag prints it out using the <s:property /> tag. The separator attribute separates the val into entries of the iterator. This generates an iterator, but only 3 entries will be available in the iterator generated, namely “JAVA”, “HTML”, “CSS” respectivelybecause count attribute is set to 3.
