为什么我把Servlet的class文件放在tomcat\Webapps\ch03\WEB-INF\classes\com\dytiger\servlets目录中下,
用Http://localhost/ch03/servlet/com.dytiger.servlets显示,IE总是报404错误?而examples下的官方的

Servlet例程确没问题呢?
JAVA_HOME和CLASSPATH等书上说的参数都设置正确了,而且在编译后也重新启动Tomcat了.请前辈指教,谢谢.

代码是:
package com.dytiger.servlets
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class FirstServlets extends HttpServlet {

public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out;
String title = "Servlet Example";
response.setContentType("text/html");
out = response.getWriter();
out.println("<html><head><title>");
out.println(title);
out.println("</title></head><body>");
out.println("<h1>This is an example servlet.</h1>");
out.println("</body></html>");
out.close();
}

public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}

在WEB-INF目录下添加web.xml文件,问题解决.以下是XML文件的内容.

<?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-mapping>
    <servlet-name>invoker</servlet-name>
    <url-pattern>/servlet/*</url-pattern>
  </servlet-mapping>

</web-app>
