1. JSP Files
=========
a) Calling page
---------------------
<%@ taglib uri="http://struts.apache.org/tags-bean"; prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html"; prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic"; prefix="logic" %>
<html:html lang="true">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title><bean:message key="welcome.title"/></title>
</head>
<body style="background-color: white">
<form action="getValue.do" method="post">
<input type="submit" value="Get Value" />
</form>
</body>
</html:html>
b) Result Page
-------------------
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>result</h1>
<jsp:useBean id="exchangeBean" scope="session"
class="com.anjib.beans.DataBean" />
<jsp:getProperty name="exchangeBean" property="sampleProperty" />
</body>
</html>
2. Bean Class
===========
package com.anjib.beans;
import java.io.Serializable;
public class DataBean implements Serializable {
private String sampleProperty;
public DataBean() {
}
public String getSampleProperty() {
return sampleProperty;
}
public void setSampleProperty(String value) {
this.sampleProperty = value;
}
}
3. Action Class
============
package com.anjib.actions;
import com.anjib.beans.DataBean;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class GetValueAction extends org.apache.struts.action.Action {
private static final String SUCCESS = "success";
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
DataBean myBean = new DataBean();
myBean.setSampleProperty("Anjib");
System.out.println("Bean Value: " + myBean.getSampleProperty());
return mapping.findForward(SUCCESS);
}
}
When I run this app I get null as result.

Hi All,
I am looking for the simple example of using beans and tag in Struts
to avoid using scriptlets. I am trying to get concept of using tag to
access result from back end using the beans. It will be very helpful
if some one can provide me a link or example which I can look into.
Thanks
Anjib
