JAXB schema validation error with CXF - JAXBException occurred : cvc-elt.1: Cannot find the declaration of element

Question

I have a REST service with CXF 3.0.1 which accepts an XML message in a HTTP POST payload. The XML payload is getting unmarshalled to an Object by JAXB .

I am trying to validate the XML through an XSD schema and I have configured the XSD in CXF but I keep getting the error below

JAXBException occurred : cvc-elt.1: Cannot find the declaration of element 'incident'.. cvc-elt.1: Cannot find the declaration of element 'incident'..

NOTE: incident is my root element

What I understand from that is that XSD is successfully registered by CXF but something is wrong in the JAXB side.

I have tried many possible solutions related to that error but none worked.

Any ideas

Thanks

Here is my configuration

Service

@Path("incident") 
public class CreateIncident { 
        @POST 
        @Consumes({ MediaType.APPLICATION_XML}) 
        public Response createIncident(Incident incident) { 
                        //code 
        } 
}

JAXB Object

@XmlRootElement(name = "incident") 
@XmlAccessorType(XmlAccessType.FIELD) 
public class Incident extends Event { 
        public Incident() { 
                super("incident"); 
        } 

        @XmlElement
        private String importProfile;

        @XmlElement
        private String eventTitle; 

        public String getImportProfile() { 
                return importProfile; 
        } 

        public void setImportProfile(String importProfile) { 
                this.importProfile = importProfile; 
        } 

        public String getEventTitle() {
                return eventTitle;
        }

        public void setEventTitle(String eventTitle) {
                this.eventTitle = eventTitle;
        }
}

Event:

public class Event {

    String eventType;

    public Event(String eventType) {
        this.eventType = eventType;
    }

    public String getEventType(){
        return eventType;
    }
}

My XSD

<?xml version="1.0" encoding="UTF-8"?>
<schema
    xmlns="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://www.ba.com/schema/BAassystWrapper/incident"
    elementFormDefault="qualified">
    <element name="incident">
        <complexType>
            <sequence>
                <element name="importProfile">
                    <simpleType>
                        <restriction base="string">
                            <minLength value="1"></minLength>
                            <maxLength value="254"></maxLength>
                        </restriction>
                    </simpleType>
                </element>
                <element name="eventTitle">
                    <simpleType>
                        <restriction base="string">
                            <minLength value="1"></minLength>
                            <maxLength value="890"></maxLength>
                        </restriction>
                    </simpleType>
                </element>
            </sequence>
        </complexType>
    </element>
</schema>

The XML that I pass

<incident>
    <importProfile>Test text</importProfile>
    <eventTitle>Test text</eventTitle>
</incident>

CXF Config

Answer 1

THe root elements need to be namespace qualified. Thus, the incoming XML needs to be something like:

<incident xmlns="http://www.ba.com/.......">

Answer 2

Since you have not defined namesapce in @XmlRootElement remove the namespace from the input.

@XmlRootElement(name = "incident") 
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso({Event.class}) 
public class Incident extends Event { 
        public Incident() { 
                super("incident"); 
        }

    //fields, getters and setters
}

And in event class add default constructor

public Event(){

}

However its better to use xjc plugin and wadl2java/wsdl2java plugin and generate jaxb classes from xsd, which would save lots of time when you change xsd frequently and also use xmlns
