访问显示结果出错，如下提示
type Status reportmessage ForeGoundServletdescription The requested resource (ForeGoundServlet) is not available.这是怎么回事呢

Answer 1

你的路径不是配置成这样的么？/foreground/ForeGoundServlet

Answer 2

试下<a href="/foreground/ForeGoundServlet?action=logIn">登录 </a> 

Answer 3

/foreground/ForeGoundServlet
你自己配制的这个url阿

Answer 4

改完还是不行
type Status reportmessage /foreground/ForeGoundServletdescription The requested resource (/foreground/ForeGoundServlet) is not available.

Answer 5

foreground/ForeGoundServlet试试，不要前面的"/"

Answer 6

或者配置文件中改为：
<servlet>
      <servlet-name>ForeGoundServlet</servlet-name>
      <servlet-class>com.shop.servlet.ForeGoundServlet</servlet-class>
</servlet>
<servlet-mapping>
      <servlet-name>ForeGoundServlet</servlet-name>
      <url-pattern>/ForeGoundServlet</url-pattern>
</servlet-mapping>    <a href="ForeGoundServlet?action=logIn">登录 </a> 这样就可以访问了！！！

Answer 7

foreground/ForeGoundServlet  你前面那里设置应该写上去

Answer 8

jsp文件： <a href="ForeGoundServlet?action=logIn">登录 </a>
<servlet>
         <servlet-name>ForeGoundServlet</servlet-name>
         <servlet-class>com.shop.servlet.ForeGoundServlet</servlet-class>
    </servlet>
    <servlet-mapping>
         <servlet-name>ForeGoundServlet</servlet-name>
         <url-pattern>/ForeGoundServlet</url-pattern>
    </servlet-mapping>   

Answer 9

很显然是路径配置错了
应该把/foreground/ForeGoundServlet中的/foreground去掉就可以了。

Answer 10

<a href="foreground/ForeGoundServlet?action=logIn">登录 </a> 

Answer 11

第一种第二种
<servlet>
         <servlet-name>ForeGoundServlet</servlet-name>
         <servlet-class>com.shop.servlet.ForeGoundServlet</servlet-class>
    </servlet>
    <servlet-mapping>
         <servlet-name>ForeGoundServlet</servlet-name>
         <url-pattern>/foreground/ForeGoundServlet</url-pattern>
    </servlet-mapping> 
<a href="foreground/ForeGoundServlet?action=logIn">…
如果这里写成这样<a href="ForeGoundServlet?action=logIn">…就找不到这个servlet
