How to creating website using servlet
Servlet is a Java software component that extends the capabilities of a server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API
Install a Java Development Kit (JDK) on your computer. You will also need to install a Java Integrated Development Environment (IDE) such as Eclipse or IntelliJ IDEA.
Create a new project in your IDE and add the necessary libraries and dependencies. You will need to include the servlet-api library, which contains the classes and interfaces required to create servlets.
Write a servlet class that extends the HttpServlet class and overrides the doGet or doPost method. The doGet method is called when a client issues an HTTP GET request to the servlet, while the doPost method is called when a client submits an HTTP POST request.
In your servlet class, use the PrintWriter object to generate the HTML content that will be displayed on the website. You can also use other Java classes such as StringBuilder to build the HTML content.
Deploy the servlet to a web server such as Apache Tomcat.
Access the servlet from a web browser using its URL.
Here is a simple example of a servlet that generates an HTML page with a heading and a paragraph:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// Set the content type of the response
response.setContentType("text/html");
// Get the printwriter object to generate HTML content
PrintWriter out = response.getWriter();
// Generate the HTML content
out.println("<html>");
out.println("<head>");
out.println("<title>Hello, World!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello, World!</h1>");
out.println("<p>Welcome to my website.</p>");
out.println("</body>");
out.println("</html>");
}
}
