Problem loading REST service

[Brad O'Hearne <br...@neurofire.com>]

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 web.xml:

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
				class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean">
				<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
