为什么weblogic不支持在jsp中调用getServletContext()?

错误如下：
Compilation of 'C:\bea\user_projects\mydomain\myserver\.wlnotdelete\DefaultWebApp_DefaultWebApp_4328039\jsp_servlet\__login.java' failed:
--------------------------------------------------------------------------------

说得很清楚嘛，找不到 getServletContext ()方法
改用application试试，weblogic是直接用application的
