Spring：从jsp访问scoped bean时出错

Question

我学会了如何从jsp访问会话范围的sping bean但是出现了以下错误：

No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? scoped beans from jsp

request.getSession().getAttribute("scopedTarget.otmSessionHolder")).getUserVO()

我的web.xml：

 <listener>
            <description>Spring Context Listener</description>
            <display-name>Spring Context Listener</display-name>
            <listener-class>
                org.springframework.web.context.ContextLoaderListener
            </listener-class>
        </listener>

        <listener>
            <display-name>Request Context Listener</display-name>
            <listener-class>
                org.springframework.web.context.request.RequestContextListener
            </listener-class>
        </listener>

但我仍然得到这个例外 我使用sitemesh decorator作为模板。已经通过这些论坛，但无济于事。亲切地帮助我
