Hello,
I get the following marshaling error when invoking my service. I am
using CXF 2.1.1.

My service has just one method implemented.
public List<Message> getMessages(String filter);
Message is an interface and I tied the interface to the implementation
using JAXB XmlJavaTypeAdapter and my adapter code is shown below.
public class MessageAdapter extends XmlAdapter<MessageImpl, Message> {
public MessageImpl marshal(Message v) throws Exception {
return (MessageImpl)v;
}
public Message unmarshal(MessageImpl v) throws Exception {
return v;
}
}
Am I missing anything here?
Appreciate any help.
Best regards,
Arul
