I need suggestions on what is the best technology I should use to implement my web services, my service is a full fledged service whose response is complex type and also includes attachments. Please suggest me what is the technology , I should use, there are so many of them apache-axsis, jax-rpc, CXF , restful , and many more . Like spring is a framework , or struts is nice framework , what in web services is the most widely used ?
IMHO there is nothing like best or most widely used web service framework. It all depends upon requirement and individual's flair and comfort level. Personally I prefer to go with standards and latest is the JAX-WS. CXF also provides supports for JAX-WS interfaces. Do some research according to your requirement and take an informed decision.
