Subject why Axis doesn't preserve Inheritance ?
Date Tue, 01 Mar 2005 12:02:23 GMT
Hi All,

I am using AXIS 1.2 RC2 and trying to expose an EJB as web service
with below wsdl which is somewhat handcrafted  to support java
collections using my custom AXIS (De)Serialzers.

I have 2 questions here now.

1. Even though the above WSDL is "validated ok" by WSAD'S WSDL
Validator, Altova's XMLSpy say it is invalid and reports an error
"Unexpected element 'extension' in element 'complexType'. Can anyone
please tell me why is this error occurring ?        Is my WSDL correct
?


2. I have taken the above WSDL and feeded to axis to generate stubs
but AXIS does not preserve inheritance among  Forecast class and its
super class ParentForecast class. The Forecast java file does not
extend ParentForecast class.  Why is this strange behavior from AXIS's
WSDL2Java Code Generator ?





Thanks & Regards,
Kumar.
