J2EE Misconfiguration: Missing Servlet Mapping

ABSTRACT

web.xml 中定義的 Servlet 必須通過相應的 servlet 映射才能訪問。

EXPLANATION

缺少有效的 servlet 映射會阻止用戶對未映射的 servlet 的所有訪問。

例 1：web.xml 中的以下條目定義了 ExampleServlet，但未定義相應的 servlet 映射。


<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<servlet>
<servlet-name>ExampleServlet</servlet-name>
<servlet-class>com.class.ExampleServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

</web-app>
