Struts Tag:

bean:struts Tag -is used to create a new bean containing one of the standard Struts framework configuration objects. This tag retrieve the value of the specified Struts internal configuration object, and define it as a scripting variable. Which is accessible as a remainder of the current page and as a attribute of page scope.

Note: Must specify exactly one of the

formBean
forward and
mapping
Attributes to select the configuration object to be exposed
( If any type of problem occurs while retrieving the specified configuration object then exception
will be thrown).

Name	Description
id	This attribute specifies the name of the scripting variable (and associated page scope attribute) that will be made available with the value of the specified Struts internal configuration object.
formBean	The formBean attribute specifies the name of the Struts `ActionFormBean` definition object to be exposed.
forward	The forward attribute specifies the name of the global Struts `ActionForward` definition object to be exposed.
mapping	The mapping attribute specifies the matching path of the Struts `ActionMapping` definition object to be exposed.

Example Illustrating the use of the Struts<bean:struts> tag.
Here you will learn to use the Struts Html<bean:struts>tag.
We will cover an example that will show a working of<bean:struts>tag.

Example code :
Creating an Action Class
Develop a simple action class BeanStrutsAction.java .


package action;



import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionForward;



public class BeanStrutsAction extends Action {

 private final static String SUCCESS = "success";

  public ActionForward execute(ActionMapping mapping, 

	ActionForm  form,HttpServletRequest request, 

	HttpServletResponse response)

  throws Exception {  

  return mapping.findForward(SUCCESS);  

  }

}

Creating Form Bean :
Develop a simple Form Bean class BeanStrutsActionForm.java .




package actionForm;



import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionMessage;



public class BeanStrutsActionForm extends

   org.apache.struts.action.ActionForm{

  

  public BeanStrutsActionForm() {

  super();  

  }  

}

Defining form Bean in struts-config.xml file :
Add the following entry in the struts-config.xml file for Form Bean.


<form-beans>

  <form-bean name="BeanStrutsActionForm" 

 
    

type="actionForm.BeanStrutsActionForm"/>  

  </form-beans>

Developing the Action Mapping in the struts-config.xml :


	<action input="/" name="BeanStrutsActionForm" 

		path="/BeanStrutsAction" scope="session" 

	type="action.BeanStrutsAction" validate="false">

	<forward name="success"  path="/beanStrutsTag.jsp"/>

 </action>

Developing the beanStrutsTag.jsp page :

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
  <head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  </head>
  <body bgcolor="#999933">

  <h3><font color="#33FF33">bean:struts Tag Demo</font></h3>
  <bean:struts id="mapping" mapping="/BeanStrutsAction"/>
  <bean:struts id="fwd" forward="welcome"/>

  <TABLE BORDER="2">
  <TR>
  <Th><font color="#33FF33">Config Object Name</font></Th>
  <Th><font color="#33FF33">Config Object Value</font></Th>
  </TR>
  <TR>
  <TD><font color="#33FF33">mapping</font></TD>
  <TD><bean:write name="mapping"/></TD>
  </TR>
  <TR>
  <TD><font color="#33FF33">fwd</font></TD>
  <TD><bean:write name="fwd"/></TD>
  </TR>
  </TABLE>

  </body>
</html>

Add the following line in the index.jsp to call the form :

<a href="./BeanStrutsAction.do">beanStrutsTagDemo</a><br/>




Building and Testing the Example:
   
    
Build , deploy and Test  the application . 

Open the browser and navigate to the


   
    
 beanStrutsTag.jsp

   
    

 
page

   
    



Your browser displays the following page

   
    

 beanStrutsTag.jsp


   
    
 
and see the output.Output:
