Hi,

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.

    Thanks,
    Sash

    "sash",
    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

    thanks,
    Dave
