JaxB transforming empty element into null when unmarshalling

Question

I have a WSDl element something like :

<xs:element maxOccurs="unbounded" minOccurs="0" name="listElement" nillable="true" type="tns:test"></xs:element>

in the SOAP request if i send empty element for listElement like :

<listElement/>

Then JaxB is creating something like :

listElement= new Arraylist<Test>();
listElement.add(new Test());

So i am getting listElement as a single arrayed with Test Object.

I want to do something which can set the listElement to Null when empty element is passed. I can 't use @XMLJavaAdapter annotation's because this is contract first and all the input objects are generated one.

I need to add some kind of binding at WSDL level or to Generation level.

Any Help will be highly APPRECIATED?

Answer 1

If the listElement element really represents null then it should be sent as follows:

<listElement xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>

Doing any sort of special handling is ultimately going to cause you trouble.
