stub + skeleton

[lukchiuming]

just finished axis User Guide with a few questions :

- there are 2 ways to deploy / call a web service
1) (without using / generate stub + skeletons) --> example1 in axis
samples
--> call web service using --> Call call = (Call) service.createCall();

2) (generate stub + skeletons using WSDL2Java) example6 in axis samples

--> call web service using -->
WidgetPriceServiceLocator().getWidgetPrice()

QUESTION 1 : what are the difference the 2 ways --> deploy / calling a
web service?

QUESTION 2 : is the 2nd way (using stub) better? since just run
WSDL2Java then i can call web service in my client code + all code
generated automatically

QUESTION 3 : is all other web service engine (.NET / PHP / Perl) has t
his 2 ways of deloyment as in axis? -OR- all web service have to
generate stub + skeletons?

Thanks
