Java First Development trouble

[blacksheep <eg...@gmail.com>]

Hi,

I am developing a Adobe Flex web application that will communicate with back
end through WebService tag. Flex uses RPC-literal type communication with
the WS. 

To do this I chose CXF. I used Java First Development style and completed my
JPA entity definitions and JpaDaoSupport classes. Then, I defined an
interface and annotated the methods with JAX-WS2.0 style. I also generated
my wsdl by using java2wsdl tool. 

Next, I followed the CXF Spring sample and finally I got such an endpoint:
<jaxws:endpoint id="AFServices" implementor="#AFInfoOps"
address="/AFOperations" />

At this point my first question is whether I have to use wsdl2java to
generate the class files. If so, I will lose JPA annotations. Since I follow
the Spring sample I have not used the wsdl2java tool. 

Then, I started my web app in debug mode let the Flex client makes a call.
Everything went well until the JPA entity get serialized into XML. I got the
following error:
