Hi,

I need some community inputs on the following: -

- I like to go forward with Frank's suggestion that the schemalocation be
input to Java2WSDL along with the corresponding namespaces.  Ofcourse this
could make the commandline lengthy, but then may be we can have an XML
Config File to capture all inputs to Java2WSDL.  This will be optional...
i.e. use either command line or xml config file.  Any comments on this
approach?
-  If during generation of the WSDL, the tool discovers that there is no
schemalocation specified for a namespace that is to be imported then we
print a message to the console but continue with the WSDL generation so that
schemalocations could be later added.  Can the schemalocation default to
"*.xsd" when not specified?  I see something of this sort in the
XSDHelperImpl where when schemaLocaiton is not specified it is assumed to be
"*.xsd".

Thanks

- Venkat

Frank, I entirely endorse your viewpoint about the schemalocation.  Yes, I
think this must be input during deployment or during the time of running
Java2WSDL.  This would be more reliable than 'assuming' schemalocations
annotated in the SDO Types.

About the point on throwing an exception when isXSD(type) is true, I too
perceive it as an approach that will safeguard data consistency.  Especially
from the following - "the generated XSD validates a different set of
documents than the original XSD" and some sample round-trips that I tried I
believe that this is important lest which the user will be caught unaware.

Thanks.
