Problem loading REST service

Tue, 01 Apr 2008 00:16:37 -0700 

Hello,
I have what is probably a fairly simple problem. I am trying to load a RESTful service in Tomcat 6.x using Spring. When I start Tomcat, I receive an Exception -- here's the Exception received:

us.service.brad.com/}IUserServiceService from class

Here is my beans.xml

        <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

        <jaxws:endpoint id="userService"
                implementor="com.brad.service.us.UserService"
                address="/userService"
                bindingUri="http://apache.org/cxf/binding/http";>
                <jaxws:serviceFactory>
                        <bean

                                <property name="wrapped" value="true" />
                        </bean>
                </jaxws:serviceFactory>
        </jaxws:endpoint>
</beans>


Does anyone have any idea what the problem is? I have been through all  
of the documentation and I cannot see the problem. I am wondering if  
there is some potential dependency issue. I have tried both the 2.0.3  
and 2.0.4 versions of the CXF jars, and I have also tried using the  
spring bean approach in the beans.xml file instead of the jaxws  
endpoint approach. Everything produces the same error.


Your help is appreciated!

Thanks,

Brad
