Marshaller and Unmarshaller Again

[siuyiuyiu]

Thanks a lot a quick reply!
Yes, I forgot to set the setMarshaller and setUnmarshaller method

But now, I am facing another questions
1) (Unmarshal) I cannot get the attribute value of the xml file, after it converts into object, but the element value is fine
<map-to xml="eFitnessProtocol"/>
<field name="Xmlns" set-method="setXmlns" get-method="getXmlns" type="java.lang.String"><bind-xml name="xmlns" node="attribute"/>
</field>

2) (marshal) I try to use the object (that is just converted by unmarshal class ) to convert back into xml file by using marshal class. But I don't know why it only return the root, no other element. I have tried if the element type is just a string type, there is no problem, but the type is defined by us, then it does not work.
(I have set the mapping file in applcationcontext file.)

if the xml file with namespace, can I using marshal or unmarshal class to do conversion?

thanks
