I generated Java files from WSDL with WSDL2Java converter, but I don\'t know how can I use service with these files, because there are no examples. I\'m implementing client side
Normally a client doesn't instantiate a stub in Web Services, you would use the service locator and call the get method. I can't tell from your question, but if you are asking a more general "Where do I get JavaDocs (or such) to better understand the API", you would have to tell use which WS you are using.
