This is due to different interpretations of the "unwrapping" rules.
CXF has generally taken a relatively strict interpretation which doesn't allow
element references when unwrapping operations. Thus, it wouldn't consider
your wsdl as unwrappable and you would need to pass an "Echo" object into the
"invoke" method, not a String. For the command line, there is an
"allowElementReferences" flag to wsdl2java to allow it, but there isn't
anything on the dynamic clients to allow it at this point.
I've just added a flag to the Dynamic client to be able to turn this on there
as well. This will be available in 2.4.1.
