How to Display Context Parameters Using Servlets?

The following example code demonstrates How to Display Context Parameters Using Servlets.

Here is an example of a servlet that creates and displays context parameters.

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class ContextInfoServlet extends HttpServlet {

  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response)
      throws ServletException, IOException {
    ServletContext context = getServletContext();
    context.setAttribute("database", "Oracle");
    context.setAttribute("server", "Apache Tomcat");
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head>");
    out.println("<title>Context Information</title>");
    out.println("</head>");
    out.println("<body>");
    out.println("<h1>Context Information</h1>");
    out.println("<p>Database: " + context.getAttribute("database") + "</p>");
    out.println("<p>Server: " + context.getAttribute("server") + "</p>");
    out.println("</body>");
    out.println("</html>");
  }
}

In this example, the ContextInfoServlet class handles GET requests. The servlet creates two context parameters, database and server, using the setAttribute method of the ServletContext object. The values of the context parameters are retrieved using the getAttribute method and displayed in an HTML page.
