I want to create a web service that returns multiple asynchronous responses
on a clients call. Though i intend a different use, one simple use case
could be that the requestor asks to be notified when mails arrive at his
mail box.

Is there a way to return a response from within a web service function,
without exiting it? Does Axis provide any server side classes for that

I know that notification is still an open issue in the WSDL spec, and
wsdl2java does not create an appropriate class when I provide a
notification operation in the WSDL.

Is it possible anyway?

thanks in advance,
