Dimuthu Gamage commented on AXIS2C-768:
---------------------------------------
Hi Bill,
The patch is applied, except the line 3468 where you suggest NULL as the return
type in failure in that particular function, But there are cases where the
retun type is a simple type like int, float. Currently I commented that piece
of code,

> I receive this failure both with the WSDL2C released in Axis2-1.3 and in the
> current nightly build I downloaded yesterday. Of course, it is a little
> difficult to isolate what in the WSDL is causing the failure, as no stub code
> is generated that might hint at the problem area. The same WSDL is accepted
> by the Axis2 WSDL2Java utility, so the issue is specific to C code
> generation. As the WSDL2Java utility accepts the file, this suggests that
> the WSDL itself is valid. If -d none is specified on the command line, the
> WSDL2C utility runs to completion, so the issue is specific to the generation
> of the C data bindings.
