Asynchronous web service

I am trying to understand the asynchronous web service (using http transport). I had a few questions, it would be very helpful of some one can suggest any links, books or even answer the questions.

  • What are asynchronous web-services?

  • What I have understood is that whenever a web-service is invoked the client continues its execution and specifies a callback method (like Axis2). How does the call back happen?
  • How can we know that the service is asynchronous from the WSDL ? An Asynchronous web service I had seen had specified some ws-addressing information for the header. Will this be used for generating the reply, asynchronously?
  • How can I write a client?

  • Any help would be appreciated.

    Welcome back to the JavaRanch!

    We're a friendly group, but we do require members to have valid display names.

    Display names must be two words: your first name, a space, then your last name. Fictitious names are not allowed.

    Please edit your profile and correct your display name since accounts with invalid display names get deleted, often without warning
