This is an example of how to pass parameters from one JSP page to another. JavaServer Pages (JSP) is a server-side programming technology that enables the creation of dynamic, platform-independent method for building Web-based applications. JSP have access to the entire family of Java APIs, including the JDBC API to access enterprise databases. In order to pass parameters from one JSP page to another we have created two JSP pages, as shown below:
Caller.jspuses thejsp:includeaction, that includes the pageCallee.jspat the time the page is requested. It uses thejsp:paramproperty inside thejsp:includetag to set values to one or more parameters passed to the other page.Callee.jsppage uses the request object that is an instance of ajavax.servlet.http.HttpServletRequestobject. Each time a client requests a page the JSP engine creates a new object to represent that request. The request object provides methods to get HTTP header information including form data, cookies, HTTP methods. Using thegetParameter(String name)it gets the value of a request parameter as a String, here is gets the value of the parameter passed to is by Caller.jsp.
Let’s take a look at the code snippet that follows:
Caller.jsp
<%@ page language="java" contentType="text/html;charset=UTF-8" %> <html> <head> <title>Java Code Geeks Snippets - Pass Parameters to other JSP Page</title> </head> <body> This is the caller JSP page. <jsp:include page="Callee.jsp"> <jsp:param name="param1" value="value1"/> <jsp:param name="param2" value="value2"/> </jsp:include> </body>
Callee.jsp
<%@ page language="java" contentType="text/html;charset=UTF-8" %>
<html>
<head>
<title>Java Code Geeks Snippets - Pass Parameters to other JSP Page</title>
</head>
<body>
This is the callee JSP page.
param1: <%= request.getParameter("param1") %>
param2: <%= request.getParameter("param2") %>
</body>
URL:
http://myhost:8080/jcgsnippets/Caller.jsp
Output:
This is the caller JSP page. This is the callee JSP page. param1: value1 param2: value2
This was an example of how to pass parameters from one JSP page to another in Java.
I have common jsp(Ex: test.jsp which has a common code snippet) which is included in all the remaining jsps(Ex Exam1.jsp, Exam2.jsp …..), so how can i pass the objects from Exam1.jsp to test.jsp and Exam2.jsp to test.jsp.
