i have followed the steps given here. on typing "http://localhost:8080" i do get the apache tomcat page. i suppose that should mean that my tomcat server is up and running. but whn i try to run my servlet that is placed in the directories as it has been mentioned here, the browser responds "HTTP Status 404 - /java_mail/hello" wht could be the problem?
please help me out of this...

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.
<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>
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/webapplicationfolder_name/HelloWorld

import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public class servlet1 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet NewServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet NewServlet at " + request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
}
}
my maping is like:
<servlet-mapping>
<servlet-name>S1</servlet-name>
<servlet-url>/hello</servlet-url>
</servlet-mapping>
The folder locations are as below:
webapps>jmail>WEB-INF(contains web.xml)>classes>(contains servlet1.java)
I have started the server using the startup.bat file. and have checked if the server is running by typing "localhost:8080" in my browser and it seems to be working fine. but when i type "localhost:8080/jmail/hello" It shows: Apache Tomcat/6.0.20
Apache Tomcat/6.0.20> HTTP Status 404 - /jmail/hello
type Status report
message /jmail/hello
description The requested resource (/jmail/hello) is not available.
Apache Tomcat/6.0.20Apache Tomcat/6.0.20
Apache Tomcat/6.0.20
i cant understand whats wrong.
is it the server that might be creating issues?
