technology (JAX-RPC, Axis, SOAP, REST etc.) to implement web services ?

[Edward Chen]

In an interview, I am asked a question :

under what scenario we should use which technology (JAX-RPC, Axis, SOAP, REST etc.) to implement web services ? what is pros and cons ?

here, my first question is , why they list all "JAX-RPC, Axis, SOAP, REST " as technology ? In my understanding, SOAP is just a protocol, but Axis is vendor product to implement SOAP.

Anyway, how to answer this question ?

Thanks.

I think the "etc." part is important. They just listed some technologies and implementations to give you an idea of the solution space. So the important points they wanted you to address were most likely a) whether or not to use web services, b) whether to use SOAP or REST, c) the fact that JAX-RPC is obsolete and should no longer be used.
