经理,我的servlet存放如下
G:/tomcat/webapps/lab03/WEB-INF/classes/scwcd/lab03/LoginServlet.class

web.xml中配置如下:
<web-app>
   <servlet>
      <servlet-name>LoginServlet</servlet-name>
      <servlet-class>scwcd.lab03.LoginServlet</servlet-class>
    </servlet>
   <servlet>

      <servlet-name>EnglishLogin</servlet-name>
      <servlet-class>scwcd.lab03.LoginServlet</servlet-class>
      <init-param>
         <param-name>message</param-name>
         <param-value>Welcome</param-value>
      </init-param>
   </servlet>

   <servlet-mapping>
      <servlet-name>EnglishLogin</servlet-name>
      <url-pattern>/ENG/Login</url-pattern>
   </servlet-mapping>

</web-app>

login3.html内容如下:
<HTML>
<BODY>
<H2>Login Page</H3>

<TABLE>
<TR>
     <TD>Name:</TD>
     <TD><INPUT TYPE='text' NAME='userid'></TD>
</TR>
<TR>
     <TD>Password:</TD>
     <TD><INPUT TYPE='password' NAME='passwd'></TD>
</TR>
</TABLE>

</FORM>
</BODY>
</HTML>

ie中输入,
http://localhost:8080/lab03/login3.html
输入用户,密码后submit
转到 http://localhost:8080/lab03/ENG/Login,
可以正确调用servlet(LoginServlet.class),得到返回结果:Welcome, lwl

而我直接在ie中输入 http://localhost:8080/lab03/servlet/LoginServlet想调用servlet(LoginServlet.class),却返回

HTTP Status 404 - /lab03/servlet/LoginServlet

--------------------------------------------------------------------------------

type Status report

message /lab03/servlet/LoginServlet

description The requested resource (/lab03/servlet/LoginServlet) is not available.

--------------------------------------------------------------------------------

Apache Tomcat/5.5.20

请问这是什么回事？servlet不是可以通过虚拟名称调用吗？
谢谢

另外,我在G:/tomcat/webapps/ROOT/WEB-INF下建了classes目录，然后将MyFirstServlet.class放在classes下，
想用 http://localhost:8080/servlet/MyFirstServlet调用,也是返回
HTTP Status 404 - /servlet/MyFirstServlet

--------------------------------------------------------------------------------

type Status report

message /servlet/MyFirstServlet

description The requested resource (/servlet/MyFirstServlet) is not available.

--------------------------------------------------------------------------------

Apache Tomcat/5.5.20

是不是因为servlet规范改了呢?我在网上查又没查到

--------------------------------------------------------------------------------

type Status report

message /servlet/MyFirstServlet

description The requested resource (/servlet/MyFirstServlet) is not available.
