Generator Tag (Control Tags) Using Count Attributes

     

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

Add the following code snippet into the struts.xml file.

struts.xml 

<action name="GeneratorTagCountAttribute" class="net.roseindia.GeneratorTag">
  <result>/pages/genericTags/GeneratorTagCountAttribute.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 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 5 entries will be available in the iterator generated, namely 'www.Roseindia.net, Deepak Kumar, Sushil Kumar, Vinod Kumar, Amit Kumar' respectively because count attribute is set to 5.

GeneratorTagCountAttribute.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>

  <head>
  <title> Generator Tag Example! </title>

  <h1><span style="background-color: #FFFFcc">Generator Tag Example!</span></h1>
  <h3><font color="#0000FF"> Generates an Iterator With Count Arrtibute</font></h3>
  <s:generator val="%{'www.Roseindia.net,Deepak Kumar,Sushil Kumar,Vinod Kumar,
  Amit Kumar, Sanjay, Vijay '}" count="5" separator=",">
  <s:iterator>
  <s:property /><br/>
  </s:iterator>
  </s:generator>
  </body>
</html>
