Webservice Migration Problems (WLS 9.2 - WLS 10.3.2)

Question

Hi,
we're upgrading our weblogic server from version 9.2 to 10.3.2. Everything runs just fine in my testing environment except for the webservices we have.
We have 6 webservices (JAX-RPC) which use a generic set of xml schema types to which each webservice offers specialized types that extend the supertype. Here comes the problem: The ant tasks wsdlc and clientgen from wls 9.2 generates java classes that do extend from the superclass. Unfortunatley the same call from the wls 10.3.2 results in a loss of class hierarchy.
Example:
<xs:complexType name="personinfo">
<xs:sequence>
<xs:element name="firstname" type="xs:string"/>
<xs:element name="lastname" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType name="fullpersoninfo">
<xs:complexContent>
<xs:extension base="personinfo">
<xs:sequence>
<xs:element name="address" type="xs:string"/>
<xs:element name="city" type="xs:string"/>
<xs:element name="country" type="xs:string"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
On WLS 9.2 this results in the following:
class Personinfo {
class Fullpersoninfo extends Personinfo {
On WLS 10.3.2. the result differs:
class Personinfo implements Serializable {
class Fullpersoninfo implements Serializable {
Is there any way to tell the wls 10.3.2 to generate a jax-rpc webservice that obeys the extension directive?
I look forward to your replies =)

Hi Jay,
thanks for the reply. Unfortunately using the other ant task doesn't seem to help. This is a WLS8.2 Version of Clientgen (which used the attribute "clientjar" rather than "destDir"/"destFile" and expected "packagename" as a required parameter). I tried id and it seems to have a couple of problems with schema files imported in included schema files. I worked around this by importing in the schema files from the wsdl itself, but now I get a "weblogic.xml.schema.binding.BindingException: ERROR: during code compilation".

Shouldn't we be able to use a 9.2 weblogic.jar for creating webservices that run on a 10.3.2?
