web.xml-404錯誤The requested resource is not available.

404錯誤The requested resource is not available.

路徑是按web.xml配置的路徑，但是還是顯示404錯誤

This is the description of my J2EE component
This is the display name of my J2EE component
DeleteStuServlet
servlet.DeleteStuServlet

<servlet-mapping>
<servlet-name>DeleteStuServlet</servlet-name>
<url-pattern>/servlet/DeleteStuServlet</url-pattern>

訪問時是這樣的：
<a href=../servlet/DeleteStuServlet?stu_id=<%=rs.getString(3)%>>刪除</a>

最佳回答：

前面../代表父路徑，，可能是路徑的問題，，建議樓主用絕對路徑試一下，，${pageContext.request.contextPath}/servlet/DeleteStuServlet試試
