Subject Re : Lightweight Skeletons
Date Mon, 14 Jan 2002 15:36:48 GMT

I think this is good news but I don't know if I have well understood the

Say I have a web service (2 classes : the interface and the impl)

1) If I compile it with -g, parameter names are available so the skeleton is
not necessary. Am I right ?
The ?wsdl will have correct parameters (not in0, inout0 ...) 

2) If I don't compile it with -g, parameter names are not available.
Skeleton can be useful in this case because I can implement getParameterName
and init functions that will tell the parameter names.

Personnaly, I have made a skeleton (and added it in the wsdd file) but I
still don't have correct parameter names in the generated wsdl (?wsdl).

Why ?
