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.

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.
