OC4J 10.1.3 WSA -assemble "Duplicate type name" error

Question

I am trying to expose a Java class as a web service using the WSA tool assemble command. The return result of one of the methods is reasonably complex and includes two variables the classes of which both extend the same base class e.g. (bean bits missing for brevity)
public class Value extends DatasetMember {
private double value;
public class Text extends DatasetMember {
private String value;
When I attempt to assemble the web service wsa spits out
Error: uk.gov.ecoconnect.webservices.datatypes.DatasetMember - Duplicate type name "uk.gov.ecoconnect.webservices.datatypes.DatasetMember" for Java type "{http://uk.gov.ecoconnect.webservices.datatypes/}DatasetMember" found. To remove this error do not specify a single typeNamespace for all value types or specify a mapping file. This error could also be caused when an erroneous type has been used more than once.
If I use AXIS against the same classes I get at correctly generated wsdl file.
Is there any way to get wsa to generate as wsdl that utilises the <extension> element?
Is there an alternative OC4J mechanism that I could use to achieve this?
I'm guessing that if the answer to the above questions is no I guess I'm going to have to move to using AXIS instead.

Hi Tzhang,
Thanks for the udpate.
What spcific changes you made to make this work? can you please share that with us?
By looking at the exception, it looks like it's failing when trying to clear the datasource connection cache. I even opened the admin_ejb app. All it has is some MDB using JMS queues. But I didn't find any datasource references in that application.
