关于配置自己的servlet的问题(昏迷中的请教)
经过了2天的冥思苦想,已经到了精神崩溃的边缘.特向知情者请教.

我刚刚学习JSP,在安装JDK时,很顺利.配置变量,也很顺利.安装tomcat与配置时,顺利+顺利.
在C:\Tomcat 5.0\webapps\myapp\WEB-INF目录下,建立了web.xml(代码如下):
<?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>
</web-app>
然后在C:\Tomcat 5.0\webapps\myapp下建立了index.jsp代码如下:
<html> <body> <center>
Now time is: <%=new java.util.Date()%>
</center> </body> </html>
并且顺利的在http://localhost:8080/myapp/index.jsp下显示index.jsp
=================================
然后又建立了一个servlet程序,文件名为Test.java代码如下:
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();
}
}
并且顺利的生成Test.class文件,把Test\Test.class复制到WEB-INF\classes下
修改web.xml文件为:
<?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 ">
<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>
刷新http://localhost:8080/myapp/Test后页面显示为:
HTTP Status 404 - /myapp/Test
--------------------------------------------
type Status report
message /myapp/Test
description The requested resource (/myapp/Test) is not available.
