Hey can any one help me “How can we create web service using vaadin framework with step by step procedure .”
Hello Rohan,
Vaadin is not the way to go if you wish to build web services.
Vaadin is for building GUI’s for web browsers (nothing more/nothing less)
Webservices are a completely different matter, for these and java you should ask google for them.
Here a few usefull links to get an idea…
