Hello Friend,
Follow these steps:
Put servlet-api.jar inside the lib folder of apache tomcat. 1)create a servlet.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException,IOException{
response.setContentType("text/html");
PrintWriter pw = response.getWriter();
pw.println("<html>");
pw.println("<head><title>Hello World</title></title>");
pw.println("<body>");
pw.println("<h1>Hello World</h1>");
pw.println("</body></html>");
}
}
2)Go to the webapps folder of your apache tomcat and create a web application folder but it should having an appropriate name like examples.
3)Create web.xml and classes folder inside the WEB_INF folder of web application folder.
4)Copy the servlet to the classes folder.
5)Edit the web.xml to include servlet?s name and url pattern.
<web-app> <servlet> <servlet-name>HelloWorld</servlet-name> <servlet-class>HelloWorld</servlet-class> </servlet> <servlet-mapping> <servlet-name>HelloWorld</servlet-name> <url-pattern>/HelloWorld</url-pattern> </servlet-mapping> </web-app>
6)Compile your servlet.
7)Run Tomcat server by clicking the startup.bat file. This is located inside the bin folder of apache tomcat.
8)Open the browser and type the following url:
http://localhost:8080/webapplicationfoldername/HelloWorld
