Passing values from servlet to jsp
Step 1: ServletCall.jsp
[html]<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Javadomain.in</title>
</head>
<body>
Click the below button to call the servlet, then servlet will print the value in the display.jsp file
<br>
<br>
<form action="ServletValues">
<input type="submit">
</form>
</body>
</html>[/html]
Step 2: ServletValues.java
[java]import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/ServletValues")
public class ServletValues extends HttpServlet {
private static final long serialVersionUID = 1L;
public ServletValues() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
String input = "Welcome to Javadomain.in";
request.setAttribute("servlet_value",input);
RequestDispatcher rd = request.getRequestDispatcher("display.jsp");
rd.forward(request, response);
}
}[/java]
Step 3: display.jsp
[html]<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Javadomain.in</title>
</head>
<body>
The values from the servlet (ServletValues) is,
<br>
<br>
${servlet_value}
<!– servlet_value is set in the ServletValues servlet. –>
</body>
</html>[/html]
Note:
Do not forget to add the required jar files.
Download the servlet required jar files
Output: ServletCall.jsp
display.jsp
