Generator Tag (Control Tags) Example

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.roseindia.GeneratorTag">
<result>/pages/genericTags/GeneratorTag.jsp</result>
</action>

Create an action class as shown:
GeneratorTag.java


package net.roseindia;

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 <s:generator> generates a simple iterator based on the val attribute supplied and <s:iterator> tagprints 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>

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

  </span></h1>

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

  <s:generator val="%{'www.Roseindia.net,Deepak Kumar,Sushil Kumar,

  
Vinod Kumar,Amit Kumar'}" separator=",">

  <s:iterator>

  <s:property /><br/>

  </s:iterator>

  </s:generator>

  </body>

</html>
