writing a java webservice

one of the interview questions was
How will you develop a java webservice ?

All i know about webservice is there are two components
actual webservice and
webserivce client

the 'Client' invokes the 'webservice' using the WSDL.

But can anyone explain how the 'web service' is implimented in java? In my scenario i have a java webservice and a java client.

I am using eclipse. What interfaces, implimentation classes do i need
to impliment the webservice?

thanks

I want to start from scratch, I don't have wsdl or anything. All I have is
eclipse ide. What implimentation classes and interfaces do I need to create to impliment
a web service for example a webservice which has a method
called getName() which returns a string 'jay'.

Ok thx for the responses. For_yan, vectorstringcalculator.jws file, how is jws file different from java file? I am assuming it's a java file? Is this technology specific? Do all webservice technologies like
axis or cxf use .jws file?

for_yan

It is not different from .java file - the contents is exactly like java - you just chnage the extension - and that
gives axis the idea what to do with it.
Perhaps, it is not the only way - I found it very convenient.

ok thanks for sharing that. It helps. Have you worked with apache CXF? I am guessing is it just like axis but very popular , not sure why

for_yan

No I didn't have a chance to work with CXF.
