}
}

before i unmarshal, i put a validation handler i get

[ERROR]: unexpected element (uri:"test:mod_rep.xsd", local:"DocumentHeader"). Expected elements are <{}TimeSeries> 

if i don't put this validation, no error... but when i check objects value, TimeSeries is null

maybe the problem is the flx prefix?

Based on the actual error message you posted, I don't know how you could come to that conclusion. The error message rather clearly says it expected a TimeSeries element in no namespace but instead it found a DocumentHeader element in the namespace represented by your "flx" prefix.

So that's the first problem. Your document has a DocumentHeader element which the class doesn't describe.

However it looks to me like you are going to have a namespace problem. The error message does say it's expecting a TimeSeries element in no namespace, but the TimeSeries element in your document is in a namespace. Perhaps you have to mention that fact in your class?

like i said, only a few element in the xml interest me.... DocumentHeader don't
are we oblige to put every element of the xml in the class?

i come to this conclusion because if i remove prefix of every element in the xml and change my root header for

<ModeleREP>

that work fine.....

i tried to add namespace in my TimeSeries class in the XmlRootElement, i have no error but my TimeSeries class is null
