Hi Friend,
It seems that server is not getting the path of servlet.
Anyways, 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.
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/servletname
