Strits2 - Generator Tag (Control Tags)

In this section, we are going to describe the generator tag. The generator tag is a generic tag that is used to generate iterators based on different attributes passed. Here we will not pass any attribute.
Add the following code snippet into the struts.xml file.

sturts.xml
<action name="GeneratorTag" class="net.struts2.GeneratorTag">

<result>/pages/genericTags/GeneratorTag.jsp</result> 

</action>
Create an action class as shown:
GeneratorTag.java

package net.struts2; 

import com.opensymphony.xwork2.ActionSupport; 

import org.apache.struts2.util.IteratorGenerator.Converter;


public class GeneratorTag extends ActionSupport { 

  public String excute() throws Exception{

  return SUCCESS;

 }

}

Create a jsp page where the generator tag generates a simple iterator based on the val attribute supplied and tag prints it out using the 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> 

<h1><span style="background-color: #FFFFcc">Generator Tag Example!</span></h1>

<h3><font color="#0000FF"> Generates a Simple Iterator </font></h3>

 <s:generator val="%{'sarwar,Deepak Kumar,Sushil Kumar, Vinod Kumar,
Amit Kumar'}" separator=",">

  <s:iterator> 

   <s:property /><br/>

  </s:iterator> 

 </s:generator>

</body> 

</html>
