急求TOMCAT支持SERVLET的配置,最好有实例!!!

解决方案 »

  1.   

    建立自己的Servlet： 
    1.用你最熟悉的编辑器（建议使用有语法检查的java ide）新建一个servlet程序，文件名为Test.java，文件内容如下： 
    package test; 
    import java.io.IOException; 
    import java.io.PrintWriter; 
    import javax.servlet.ServletException; 
    import javax.servlet.http.HttpServlet; 
    import javax.servlet.http.HttpServletRequest; 
    import javax.servlet.http.HttpServletResponse; 
    public class Test extends HttpServlet { 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) 
    throws ServletException, IOException { 
    PrintWriter out=response.getWriter(); 
    out.println("<html><body><h1>This is a servlet test.</h1></body></html>"); 
    out.flush(); 
    } 
    } 
    2 .编译 
    将Test.java放在c:\test下，使用如下命令编译： 
    C:\Test>javac Test.java 
    然后在c:\Test下会产生一个编译后的servlet文件：Test.class 
    3 .将结构test\Test.class剪切到%CATALINA_HOME%\webapps\myapp\WEB-INF\classes下，也就是剪切那个test目录到classes目录下，如果classes目录不存在，就新建一个。 现在webapps\myapp\WEB-INF\classes下有test\Test.class的文件目录结构 
    4 .修改webapps\myapp\WEB-INF\web.xml，添加servlet和servlet-mapping 
    编辑后的web.xml如下所示: 
    <?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> 
    <display-name>My Web Application</display-name> 
    <description> 
    A application for test. 
    </description> 
    <servlet> 
    <servlet-name>Test</servlet-name> 
    <display-name>Test</display-name> 
    <description>A test Servlet</description> 
    <servlet-class>test.Test</servlet-class> 
    </servlet> 
    <servlet-mapping> 
    <servlet-name>Test</servlet-name> 
    <url-pattern>/Test</url-pattern> 
    </servlet-mapping> 
    </web-app> 
    这段话中的servlet这一段声明了你要调用的Servlet，而servlet-mapping则是将声明的servlet"映射"到地址/Test上 
    5 .好了，重启动Tomcat，启动浏览器，输入http://localhost:8080/myapp/Test 如果看到输出This is a servlet test.就说明编写的servlet成功了。 
    注意：修改了web.xml以及新加了class，都要重启Tomcat
