weblogic与Spring acegi问题

大家好
    本人将使用了Spring acegi验证框架的项目从tomcat中移植到weblogic中。tomcat能用weblogic不行。希望各位高手帮助解决.
XML配置<servlet> 
<servlet-name>contextLoaderServlet</servlet-name> 
<servlet-class>org.springframework.web.context.ContextLoaderServlet </servlet-class> 
<load-on-startup>1</load-on-startup> 
</servlet> 
  <filter-mapping>
    <filter-name>Acegi Filter Chain Proxy</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping><filter> 
<filter-name>Acegi Filter Chain Proxy</filter-name> 
<filter-class> 
org.acegisecurity.util.FilterToBeanProxy 
</filter-class> 
<init-param> 
<param-name>targetBean</param-name> 
<param-value>filterChainProxy</param-value> 
</init-param> 
</filter> 
报错如下：
