Spring mvc3 + hibernate + java + web services : <p>I want to create a web application which should communicate with other web-apps and access their db and pull and insert in my project db and push the data too. Somebody suggested me you can achieve that using web services.But i have no knowledge on that. </p>

<p>I am creating web application using spring mvc3 + Maven + hibernate + java and database is MySQL in STS IDE.  </p>

<p>Am very new to web services. Can you please suggest me how to create web service from scratch with any good step by step format and how to get web services in IDE, how to create Web service in my project and how to link my web app with other web apps to communicate with the db?</p>

<p>A million tons of thanks in advance. :)</p>
