Hi
You probably need to add an Accept header value set to application/xml when
requesting Locations or add @Produces("application/xml") on that method.
Not sure though why the list of locations is empty on POST, it appears the
incoming XML does not match the one which is produced :
<Locations><locations><id>1</id></locations></Locations>
meaning that JAXB is probably expecting tags with diff names, so it probably
should be :
<Locations>
<locations>
<id>1</id>
</locations>
</Locations>
Cheers, Sergey
