Struts Forward Action Example



In this section we  will learn about Struts ForwardAction(org.apache.struts.actions.ForwardAction). The ForwardAction is one of the Built-in Actions that is shipped with struts framework.
The org.apache.struts.actions.ForwardAction class enables a user to forward request to the specified URL. ForwardAction is an utility classs that is used in cases where a user simply needs to forward the control to an another JSP page. Linking directly a JSP  to an another, violates the MVC principles.  So we achieve this  through  action-mapping. Note that we do not  create any action class. With ForwardAction , simply create an action mapping  in the Strut Configuration and specify the location where the action will forward the request..
Here in this example you will learn more about Struts Forward Action that will help you in grasping the concept better.

No need to develop an Action Class

Developing the Action Mapping in the struts-config.xml

Create seperate action-mapping , for each page you want to link.. Note that the "type" attribute  alwaystake "org.apache.struts.actions.ForwardAction" value. Here  "parameter" attribute specifies theURL to which  the request is  forwarded . 
<action
path="/success"
type="org.apache.struts.actions.ForwardAction"
parameter="/pages/Success.jsp"
input="/pages/ForwardAction.jsp"
scope="request"
validate="false">
</action>

Developing a jsp page
Code of the jsp (ForwardAction.jsp)  to forward request to a different jsp page :

<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:html locale="true">
<HEAD>
<TITLE>Forward Action Example</TITLE>
<BODY>

<H3>Forward Action Example</H3>
<p><html:link page="/success.do">Call the Success page</html:link></p>
</html:html>
Add the following line in the index.jsp to call the form.
<li>
<html:link page="/pages/ForwardAction.jsp">Struts Forward Action</html:link>
<br>
Example shows you how to use forward class to forward request to another JSP page.
</li>

Building and Testing the Example 
To build and deploy the application go to Struts\Strutstutorial directory and type ant on the command prompt. This will deploy the application. Open the browser and navigate to the ForwardAction.jsp page. Your browser will display the following ForwardAction page.
 I hope all goes well! Look forward to seeing more Java tutorials from me in the future.

Servlets, JSP, Struts and MVC

1.General Information about servlet: Servlet Request & Response Model: There are three different players in this picture: browser, web server, and servlet Container. In many cases, a web server and a servlet container are running in a same machine even in a single virtual machine. So they are not really distinguished in many cases. Anyway, the role of the web server is to receive HTTP request and then passes it to the web container or servlet container Which then creates Java objects that represent “HTTP request” and a “session” and then dispatches the request to the servlet by invoking service() method defined in the servlet.         The most common form of client requests are HTTP GET and HTTP POST requests. In the HTTP GET request, the user entered information is appended to the URL as a query string. In the HTTP POST request, on the other hand, the user entered information is sent as data.

Hibernate Avg() Function (Aggregate Functions)

In this section, we will show you, how to use the avg() function. Hibernate supports multiple aggregate functions. When they are used in HQL queries, they return an aggregate value ( such as   avg(...), sum(...), min(...), max(...) , count(*), count(...), count(distinct ...), count(all...)   ) calculated from property values of all objects satisfying other query criteria.  Following is a aggregate function (avg() function) with their respective syntax. avg(   [   distinct   |   all   ] object.property): The   avg()   function aggregates the average value of the given column.  Table Name: insurance ID insurance_name invested_amount investement_date 2 Life Insurance 25000 0000-00-00 00:00:00 1 Givan Dhara 20000  2007-07-30 17:29:05 3 Life Insurance   500 2005-10-15 00:00:00 4 Car Insurance    2500 2005-01

Hibernate Count Query

In this section we will show you, how to use the Count Query. Hibernate supports multiple aggregate functions. when they are used in HQL queries, they return an aggregate value (such as sum, average, and count) calculated from property values of all objects satisfying other query criteria. These functions can be used along with the  distinct  and all  options, to return aggregate values calculated from only  distinct  values and all values (except null values), respectively. Following is a list of aggregate functions with their respective syntax; all of them are self-explanatory. count ( [   distinct   |   all   ] object | object.property ) count(*)  (equivalent to   count(all ...) , counts null values also) sum (   [   distinct   |   all   ] object.property) avg(   [   distinct   |   all   ] object.property) max(   [   distinct   |   all   ] object.property) min(  [  distinct  |  all  ] object.property) Here is the java code for counting the records from insurance tab
