JBoss Community

I've a problem to use abstract class in a Web Service like WebMethod output parameter.

Environment: 

- jboss-5.1.0.GA
- eclipseHelios
-windowsXp- SP3

I'm using JBOSS-5.1.0.GA and java runtime Version 6. It always return emtpry tag for abstract tag.

I have completed below step as wellWhen running under Java 6 you need to manually copy the following libraries from the JBOSS_HOME/client directory to the JBOSS_HOME/lib/endorsed directory, so that the JAX-WS 2.0 apis supported by JBossWS are used:

jbossws-native-saaj.jar
jbossws-native-jaxrpc.jar
jbossws-native-jaxws.jar
jbossws-native-jaxws-ext.jar

for below section of WSDL:

<xsd:complexType name="Personne" abstract="true" />
<xsd:complexType name="PersonnePhysique">
<xsd:complexContent>
<xsd:extension base="Personne">

<xsd:complexType name="PersonnePhysique">

        <xsd:complexContent>

          <xsd:extension base="Personne">

            <xsd:sequence>

              <xsd:element name="idFonctionnel" type="IdFonctionnel" maxOccurs="1"

                           minOccurs="1" />

              <xsd:element name="civilite" type="Civilite" maxOccurs="1"

                           minOccurs="0" />

                          minOccurs="0" />                         

            </xsd:sequence>

          </xsd:extension>

        </xsd:complexContent>

      </xsd:complexType>

Below is ant target we are using to generate code.

<target name="consume" depends="init" >
  <echo message="Génération des classes à partir du WSDL"/>

  <wsconsume
    fork="true"
    verbose="true"
    destdir="${classes.dir}"
    sourcedestdir="${srcgen.dir}"
    keep="true"
    extension ="true" 
       wsdl="../${wsdl.dir}/${wsdlName}"/>
</target>

We actualy using Personne as response from web service.

Getting below error stack:

javax.xml.ws.WebServiceException: javax.xml.bind.UnmarshalException: Unable to create an instance of com.sfr.sigc.rechercherpersonneetroles.Personne

The same was working fine with CXF stack before. Please suggest solution without changinf WSDL as we can't chnage that.
