Unable to compile Servlet

First I installed the tomcat server in C:\apache-tomcat-6.0.14 directory.

Then I created a system variable CATALINA_HOME with the value C:\apache-tomcat-6.0.14.

Then I created another system variable JAVA_HOME with the value C:\Program Files\Java\jdk1.6.0.14

Then I created another environment variable CLASSPATH with the value C:\apache-tomcat-6.0.14\lib\servlet-api.jar

Then I created my servlet file Servlet_LifeCycle.java under the folder C:\apache-tomcat-6.0.14\webapps\demo-examples. The demo-examples folder was created by me.

To compile my servlet program I did the following:

C:\apache-tomcat-6.0.14\webapps\demo-examples>javac Servlet_LifeCycle.java

But the compilation failed totally.

Hi Friend,

Follow these steps:

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 assuming examples.

4)Copy the servlet to the classes folder.

5)Edit the web.xml to include servlet?s name and url pattern.

 <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>

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
