Many thanks Simon, It was really very helpful to me and you have cleared many questions Now some more queations from my side (Again) :-)
First of all i'll explain what i have understood from your explanation... Only Tuscany client is option for callback service. (though for other client i have to right my own callback protocol) >From client side i have to pass callback uri and some other info to service and service will feedback me on that uri, so my client is also exposing wsdl and i have to put it into any server say Tomcat correct? I want to give a scenario...Say order service client makes an order call(assume client is part of a larger system), and doing some other activity.On service side it takes time to generate status. Now on client side what i have done when my client need the result, i m polling to check the status and wait till client get the result.But in callback scenario client have some callback interface. So should my client invoke method on same (client) side callback interface.. like polling(this is on client side only... no need to call service)... or service will invoke my client by callback uri? so my confusion is from client side what action should be taken, as in polling, client is calling service, now service is callingback to client? so how should client come to know about callback result? -- Many thanks Nishant Joshi
