在原有ssh项目上整合cxf时报错

严重: Servlet [HelloWorldService] in web application [/admin_iqiyi] threw load() exception

查了半天都说是未导jar包或者未配置cxf servlet，但是我都引入了
web.xml

    
        HelloWorldService    
        org.apache.cxf.transport.servlet.CXFServlet    
        1 
        
            config-location
            /WEB-INF/beans.xml
           
        
        
        HelloWorldService    
        /service/*    
    

cxf配置文件

实在是搞不明白是怎么回事，求指导
