求助eclipse下开发struts+spring+hibernate的问题

beingo

小弟新学struts+spring+hibernate开发，写了一个增加记录的应用，第一次用eclipse开发，有些错误不懂，请高手解答一下：

以下是action的主要代码
public ActionForward execute(ActionMapping mapping, ActionForm form,
                        HttpServletRequest request, HttpServletResponse response) {
                InsertUser ob =(InsertUser)getWebApplicationContext().getBean("addUser";
                User1 u=new User1();
                u.setName("曾凡明";
                u.setSchool("小学";
                ob.save(u);
                return mapping.findForward("ok";
        }
启动tomcat在ie输入/AddUserAction.do时报错：
错误信息如下:
java.lang.IllegalStateException: Root context attribute is not of type WebApplicationContext: org.codehaus.xfire.spring.GenericApplicationContext: display name [org.codehaus.xfire.spring.GenericApplicationContext;hashCode=30866355]; startup date [Sat Jun 30 16:30:52 CST 2007]; child of [org.codehaus.xfire.transport.http.XFireConfigurableServlet$GenericWebApplicationContextX: display name [org.codehaus.xfire.transport.http.XFireConfigurableServlet$GenericWebApplicationContextX;hashCode=9102426]; startup date [Sat Jun 30 16:30:51 CST 2007]; root of context hierarchy]
