Thanks Sergey but I dont think I was clear. The problem has nothing to do
with xml attributes (my bad I should not have used the word 'attribute').
The problem is that the base class elements are not being unmarshalled. For
example if I pass:
{
"id": "12",
"name": "mike"
}
Where "id" comes from a base complexType:
<xsd:complexType name="entityType" abstract="true">
<xsd:sequence>
<xsd:element name="id" type="tns:textType" minOccurs="0" maxOccurs="1" />
</xsd:sequence>
</xsd:complexType>
and "name" comes from a derived comlexType:
<xsd:complexType name="userDataType">
<xsd:complexContent>
<xsd:extension base="common:entityType">
<xsd:sequence>
<xsd:element name="name" type="xsd:string" minOccurs="0" maxOccurs="1" />
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
I am not receiving the "id" value in my JaxRS service when the object is
unmarshaled:
public void get(UserDataType user) {
assert user.getName() != null : "this passes";
assert user.getId() != null : "this fails";
}
This happens only with the base complexType elements when I unmarshall json
objects. It works fine with XML.
