I tried to post this in JIRA but it told me I dont have permission to comment on the issue so here it goes: I am experiencing the same problem described by original Reporter: Subclass information gets lost when the SOAP message is created....but not always.. if the class contains a variable of JAXBElement then the inheritance seems to work correctly for all attributes in the class. Example (constructed to explain my point, sorry if not 100% correct but the WSDL I am really dealing with is quite huge). | <complexType name="SomeType"> | <complexContent> | <sequence> | <element name="someElement" type="tns:SomeElement" minOccurs="0" maxOccurs="1"nillable="true"/> | <element name="classB" type="tns:ClassB" minOccurs="1" maxOccurs="1" nillable="true" /> | </sequence> | </complexContent> | </complexType> | Note that the minOccurrs="0" together with nillable="true" in someElement will cause wsconsume to create the JAXBElement<..> variable i was talking about: | public class SomeType{ | | @XmlElementRef(name = "someElement", namespace = "http://some.namespace.com", type = JAXBElement.class) | protected JAXBElement<SomeElement> someElement; | @XmlElement(required = true, nillable = true) | protected ClassB classB; | .... | In this example inheritance for the classB Attribute works as expected. Whereas if I alter the wsdl and set the minOccurrs of someElement to 1 thus having wsconsume create the following class: | public class SomeType{ | | @XmlElement(required=true, nillable=true) | protected SomeElement someElement; | @XmlElement(required = true, nillable = true) | protected ClassB classB; | ... | | then inheritance on classB breaks. Not sure why this is happening, but I thought this observation might help to track down the cause of this.
