How JSP Forwards a request

In this section you will study how jsp forwards a request.

The <jsp:forward> forwards the request information from one resource to the other, for example, one jsp file to other. To forward a request from one page to other, following syntax is required which forwards the request to other page. If a string or an expression represents the URL to forward the page, use the syntax:

<jsp:forward page={"relativeURL" | "<%= expression %>"} />

If you want to send one or more name/value pairs as a parameters, use the syntax:

<jsp:forward page={"relativeURL" | "<%= expression %>"} >
<jsp:param name="parameterName"value="
{parameterValue | <%= expression %>}" />+
</jsp:forward>

Here is the code of forward.jsp:

<%@ page language ="java" %>
<html>
<head><title>jsp forwarding a request</title></head>
<jsp:forward page="/jsp/welcome.jsp"/>
</html>

The above jsp page forwards the request to welcome.jsp page by using <jsp:forward page="/jsp/welcome.jsp"/>

Here is the code of welcome.jsp

<%@page language="java" %>
<html>
<head><title>jsp forwarding a request</title></head>
<body>
<h3><b>Welcome!</b></h3>
