Syntax:

1) Forwarding along with Parameters.

<jsp:forward page="display.jsp"> 
<jsp:param ... /> 
<jsp:param ... /> 
<jsp:param ... /> 
...
<jsp:param ... /> 
</jsp:forward>

2) Forwarding without parameters.

<jsp:forward page="Relative_URL_of_Page" />

Relative_URL_of_Page: If page is in the same directory where the main page resides then use page name itself as I did in the below examples.

JSP Forward Example 1 – without passing parameters

index.jsp

<html> 
<head>
<title>JSP forward action tag example</title>
</head>
<body> 
<p align="center">My main JSP page</p>
<jsp:forward page="display.jsp" /> 
</body> 
</html>

display.jsp

<html>
<head>
<title>Display Page</title>
</head>
<body>
        Hello this is a display.jsp Page
</body>
</html>

Output:
Below is the output of above cpde. It is basically the content of display.jsp, which clearly shows that index.jsp didn’t display as it forwarded the request to the display.jsp page.

JSP Forward Example 2 – with parameters

Here we are passing the parameters along with forward request. For passing parameters we are using <jsp:param> action tag. In this example we are passing 4 parameters along with forward and later we are displaying them on the forwarded page. In order to fetch the parameters on display.jsp page we are using getParameter method of request implicit object.

index.jsp

<html> 
<head>
<title>JSP forward example with parameters</title>
</head>
<body> 
<jsp:forward page="display.jsp"> 
<jsp:param name="name" value="Chaitanya" /> 
<jsp:param name="site" value="BeginnersBook.com" /> 
<jsp:param name="tutorialname" value="jsp forward action" /> 
<jsp:param name="reqcamefrom" value="index.jsp" /> 
</jsp:forward> 
</body> 
</html>

display.jsp

<html>
<head>
<title>Display Page</title>
</head>
<body>
<h2>Hello this is a display.jsp Page</h2>
        My name is: <%=request.getParameter("name")%><br>
        Website: <%=request.getParameter("site")%><br>
        Topic: <%=request.getParameter("tutorialname")%><br>
        Forward Request came from the page: <%=request.getParameter("reqcamefrom")%>
</body>
</html>

Output:
Above code directly displayed display.jsp page, which is displaying the parameters passed from index.jsp page.
