Generator Tag (Control Tags) Using an Iterator with Id Attributes
In this section, we are going to describe the generator
tag using the id
attributes.
Add the following code snippet into the struts.xml
file.
struts.xml
<action name="GeneratorTagIdAttribute" class="net.roseindia.GeneratorTag">
<result>/pages/genericTags/GeneratorTagIdAttribute.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 "id"
attribute and
<s:iterator> tag prints it out using the
<s:property /> tag. The separator attribute
separates the val into entries of the iterator.
The scriplet as shown below generates an iterator and
put it in the PageContext under the key as specified
by the id attribute.
<%
Iterator i = (Iterator) pageContext.getAttribute("myAtt");
while(i.hasNext()) {
String s = (String) i.next(); %>
<%=s%> <br/>
<% }
%>
GeneratorTagIdAttribute.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@page language="java" import="java.util.*"%>
<html>
<head>
<title> Generator Tag Example! </title>
</head>
<body>
<h1><span style="background-color: #FFFFcc">Generator Tag Example!</span></h1>

<s:generator val="%{'www.Roseindia.net,Deepak Kumar,Sushil Kumar,Vinod
Kumar,Amit Kumar'}" count="4" separator="," id="myAtt" />
<%
Iterator i = (Iterator) pageContext.getAttribute("myAtt");
while(i.hasNext()) {
String s = (String) i.next(); %>
<%=s%> <br/>
<% }
%>
</body>
