12 What Is the Use Of Servlet Context in Web.xml File

ServletContext is created by the web container at time of deploying the project.
There is only one ServletContext object per web application.

Advantage of ServletContext
• Easy to maintain if any information is shared to all the servlet, it is better to make it available for all the servlet.

Usage of ServletContext
There can be a lot of usage of ServletContext object. Some of them are as follows:

1. The object of ServletContext provides an interface between the container and servlet.
4. The ServletContext object can be used to provide inter-application communication.

How to get the object of ServletContext interface

//We can get the ServletContext object from ServletConfig object
ServletContext context=getServletConfig().getServletContext();
2. getServletContext() method of GenericServlet class returns the object of ServletContext.
//Another way to get the ServletContext object

Hi! May I ask if I can initialize a JSP page as a param-value, and if yes, how can I call it from the Servlet/JSP?

For context, I have header.jsp as ServletContext and I want to put it in all my pages.

Thank you!
