There are 9 jsp implicit objects. These objects are created by the web container that are available to all the jsp pages.
The available implicit objects are out, request, config, session, application etc.
A list of the 9 implicit objects is given below:
| Object | Type |
|---|---|
| out | JspWriter |
| request | HttpServletRequest |
| response | HttpServletResponse |
| config | ServletConfig |
| application | ServletContext |
| session | HttpSession |
| pageContext | PageContext |
| page | Object |
| exception | Throwable |
1) JSP out implicit object
For writing any data to the buffer, JSP provides an implicit object named out. It is the object of JspWriter. In case of servlet you need to write:
- PrintWriter out=response.getWriter();
But in JSP, you don’t need to write this code.
Example of out implicit object
In this example we are simply displaying date and time.
index.jsp
- <html>
- <body>
- <% out.print(“Today is:”+java.util.Calendar.getInstance().getTime()); %>
- </body>
- </html>
