高分求答：JSF中不能取得bean
web.xml中有如下配置

XML code

<context-param>
    <param-name>javax.faces.CONFIG_FILES</param-name>
    <param-value>
        ......
        /WEB-INF/faces-managed-beans-user.xml,
                ... ...
    </param-value>
</context-param>

faces-managed-beans-user.xml中有 bean的配置(alertConfigBean和ruleBean)如下：

XML code

<managed-bean>
     <managed-bean-name>alertConfigBean</managed-bean-name>
     <managed-bean-class>
           com.test.bean.rule.AlertConfigBean
     </managed-bean-class>
     <managed-bean-scope>application</managed-bean-scope>
</managed-bean>
......
    <managed-bean>
        <managed-bean-name>ruleBean</managed-bean-name>
        <managed-bean-class>
            com.infosec.secsrv.scms20.bean.rule.RuleBean
        </managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>

我想在RuleBean中取得alertConfigBean，怎么获取？
用下面的代码不可以吗？为什么取出来的是null？
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().get("alertConfigBean");
求高手解答！

你直接import，然后引用不好……

遇到同样类似问题啊...
------解决方案--------------------
在定义ruleBean时把alertConfigBean写在<property>里不行吗
------解决方案--------------------
你把FacesContext.getCurrentInstance().getExternalContext().getApplicationMap()打印一下
应该是没有给alertConfigBean实例化，当然就是空的了
