The JDeveloper version i'm using is 10.1.3.0.4.
Does anybody knows how to fix this problem?
Thanks,
Nuno

Yes, i have created a fault on one of the operations, however in the .wsdl file it does have a name attribute.
<operation name="process">
<fault name="TestError" message="client:TestErrorMessage"/>
</operation>
The fault definition in the .wsdl obtained from the process when you access it over http is somewhat different:
<fault>
<soap:fault name="TestError" use="literal" encodingStyle="" />
</fault>
