2.servlet

现在，我们该看一下servlet了！

同样，编写一个程序HelloServlet.java

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
//** Simple servlet used to test server.*/

public class HelloServlet extends HttpServlet
{
public void doGet(HttpServletRequest request,
                   HttpServletResponse response)
throws ServletException,IOException
{
  response.setContentType("text/html");
  PrintWriter out=response.getWriter();
  String docType="<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0"+
  "Transitional//EN"> ";
  out.println(docType+
  "<html> "+
  "<head><title>Hello</title></head> "+
  "<body bgcolor="#FFFF99"> "+
  "<h1>Hello</h1> "+
  "</body></html>");
}
}

编译还像上面HelloWorld.java的那样,把编译得到的.class文件copy到ROOT/WEB-INF/classes目录下，然后在ROOT/WEB-INF/下找到web.xml文件，打开编辑：

<display-name>Welcome to Tomcat</display-name>

Welcome to Tomcat
</description>

    <servlet>
        <servlet-name>org.apache.jsp.index_jsp</servlet-name>
        <servlet-class>org.apache.jsp.index_jsp</servlet-class>
    </servlet>

<servlet-mapping>
        <servlet-name>org.apache.jsp.index_jsp</servlet-name>
        <url-pattern>/index.jsp</url-pattern>
    </servlet-mapping>

    <servlet>
    <servlet-name>HelloServlet</servlet-name>
    <servlet-class>HelloServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>HelloServlet</servlet-name>
        <url-pattern>/servlet/HelloServlet</url-pattern>
    </servlet-mapping>

</web-app>

红色的部分就是我们添加进去的，<url-pattern>/servlet/HelloServlet</url-pattern>是影射到那个目录！保存！

然后重新启动你的tomcat，在浏览器中输入: http://localhost:8080/servlet/HelloServlet/

你看到什么了？？？相信你能看到米黄色的背景上有一个很大的Hello。现在，你的servlet容器也没问题了！
