Subject [jira] [Updated] (CXF-4016) JAX-WS schema generation of an Exception annoted with @WebFault that contains a property of a class annotated with @XmlRootElement causes the schema of the WSDL to generate the incorrectly
Date Fri, 13 Jan 2012 20:16:40 GMT

     [ https://issues.apache.org/jira/browse/CXF-4016?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Kulp updated CXF-4016:
-----------------------------

    Description: 
I have the following Exception Class (BusinessException) that is annotated with @WebFault.  BusinessException has a property named exceptionMessage that is of Type ExceptionMessage. ExceptionMessage is annotated with the @XmlRootElement annotation.



When CXF generates the WSDL via hitting the web wervice URL it generates a schema with an invalid element for the BusinessException element.

See the schema in question here:



{code}
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" targetNamespace="http://www.mycompany.com/platform/exception" xmlns:tns="http://www.mycompany.com/platform/exception" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="ExceptionMessage" type="tns:exceptionMessage"/>
<xs:complexType name="exceptionMessage">
<xs:sequence>
<xs:element minOccurs="0" name="classCause" type="xs:string"/>
<xs:element minOccurs="0" name="severity" type="xs:string"/>
<xs:element minOccurs="0" name="exceptionMessage" type="xs:string"/>
<xs:element minOccurs="0" name="displayMessage" type="xs:string"/>
<xs:element name="code" type="xs:int"/>
<xs:element minOccurs="0" name="informationCode" type="xs:string"/>
<xs:element minOccurs="0" name="uniqueID" type="xs:string"/>
<xs:element minOccurs="0" name="userResolution" type="xs:string"/>
<xs:element minOccurs="0" name="exceptionCause" type="xs:string"/>
<xs:element minOccurs="0" name="stack" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="BusinessException">
<xs:sequence>
<xs:element nillable="true"/>
</xs:sequence>
</xs:complexType>
<xs:element name="BusinessException" type="tns:BusinessException"/>
</xs:schema>
{code}



Notice this portion of the schema here:

{code}
<xs:complexType name="BusinessException">
<xs:sequence>
<xs:element nillable="true"/>
</xs:sequence>
</xs:complexType>
{code}

It is generating an invalid schema element "<xs:element nillable="true"/>" without a name or ref.


The problem appears to be with the fact that the ExceptionMessage class is annotated with @XmlRootElement.  If I remove the @XmlRootElement from the ExceptionMessage class it all works fine.  My problem is that the ExceptionMessage class is also used by other services in my code that need to serialize the ExceptionMessage to xml via JAXB.  And as I'm sure you already know when using the JaxbContext will throw an Exception if the class is not annotated with the @XmlRootElement.  I have been able to work around this issue by simply removing the @XmlRootElement annotation and programmatically implementing a JAXBElement object which will then allow me to use the JaxbContext without getting the non present @XmlRootElement Exception.

{code}
	QName qName = new QName("http://www.mycompany.com/platform/exception", "ExceptionMessage");
	JAXBElement<ExceptionMessage> jaxbElement = new JAXBElement<ExceptionMessage>(qName, ExceptionMessage.class, exceptionMessageObj);
{code}




So I guess what I'm asking is isn't it possible just use the simple class name for the WSDL schema name  for a class that is annotated with @XmlRootElement verus generating an invalid schema element without a name or ref?

> I have the following Exception Class (BusinessException) that is annotated with @WebFault.  BusinessException has a property named exceptionMessage that is of Type ExceptionMessage. ExceptionMessage is annotated with the @XmlRootElement annotation.
> When CXF generates the WSDL via hitting the web wervice URL it generates a schema with an invalid element for the BusinessException element.
> See the schema in question here:

> The problem appears to be with the fact that the ExceptionMessage class is annotated with @XmlRootElement.  If I remove the @XmlRootElement from the ExceptionMessage class it all works fine.  My problem is that the ExceptionMessage class is also used by other services in my code that need to serialize the ExceptionMessage to xml via JAXB.  And as I'm sure you already know when using the JaxbContext will throw an Exception if the class is not annotated with the @XmlRootElement.  I have been able to work around this issue by simply removing the @XmlRootElement annotation and programmatically implementing a JAXBElement object which will then allow me to use the JaxbContext without getting the non present @XmlRootElement Exception.
> {code}
> 	QName qName = new QName("http://www.mycompany.com/platform/exception", "ExceptionMessage");
> 	JAXBElement<ExceptionMessage> jaxbElement = new JAXBElement<ExceptionMessage>(qName, ExceptionMessage.class, exceptionMessageObj);
> {code}
> So I guess what I'm asking is isn't it possible just use the simple class name for the WSDL schema name  for a class that is annotated with @XmlRootElement verus generating an invalid schema element without a name or ref?
