How to make a CXF client in Java5?

[raylmail]

Hello CXF Team,
 
Current we are using CXF 2.2.5 in our product for publishing services, the 
system runs fine on Java 6.
 
Now we plan to integrate a satellite product in, which runs on Java 5. I tried 
to write client in the satellite product to call services published from 
flagship product.
 
When I try JaxWsProxyFactoryBean or JaxWsDynamicClientFactory for client, I 
found that some classes CXF uses don't exist in Java 5, such as:
 
    javax.xml.bind.JAXBException
    javax.xml.ws.BindingProvider

But I can find "Can CXF run with JDK 1.5? Yes." in CXF FAQ page.
Maybe I am fresh for CXF, are there some particular usage for Java 5 
environment ?
 
Any hint will be grateful :-)
 
Thanks a lot!
