Hi Friend,
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.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!--<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd"> -->
<web-app>
<servlet>
<servlet-name>Hello</servlet-name>
<servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Hello</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/servletname
