Beginner: WSDL2JAVA or Not

[Frogman]

Hi,

I'm just learning Apache Axis and it seems to me that there are 2
different ways of creating a client to access a service. One is to
manually code the client using Axis libraries. The other to generate
stub classes using the WSDL2JAVA library (I'm I correct in my
understanding?).

My question is when do you code manually and when do you generate
stubs using WSDL2JAVA? What are advantages and disadvantages?

Thanks,
