Java class in JSP
To use a Java class method in jsp first we need to
import a package inside which there is java class. We will import the package by
using page directive and one of its attribute import. To use the class inside
the jsp page we now need to create an object of the class by using the new
operator. At last use the instance of the class to access the methods of the
java file.
To perform this example we need to create a java class.
In this example we are making a class named as DateDemo inside a package.
Declare one method named returnDate() inside the class. Now in the jsp page
import the package which we have declared in the java class. This package is
used inside the page directive. Now make a object of the java class and by the
instance of the java class call the method defined inside the java class.
The code of the program is given below:
package Date;
import java.util.*;
public class DateDemo{
public Date returnDate() {
Date d=new Date();
return d;
}
}
|
<%@ page import="Date.DateDemo"%>
<html>
<head>
<title>This is the date example</title>
</head>
<body>
<% DateDemo demo = new DateDemo();
out.println("Current date : " + demo.returnDate();%>)
</body>
</html>
