Using wsdl2java to create a stub with PROPER async support

Suppose that I have a service is only one method: int generateRandomNumbers().

Can wsdl2java be used to create stubs with proper async support?

For example, the generated class should have the following methods / messages:

int generateRandomNumbers()
int generateRandomNumbers_Async(callback)

I know how to use wsdl2java to create stubs with asynchronous messages. However, this only works if the service understands asynchronous messages.

What I mean by async native support is that

  • generateRandomNumbers_Asyncis not a new message because the service only understands generateRandomNumbers, notgenerateRandomNumbers_Async
  • generateRandomNumbers_Async= calls generateRandomNumbersin another thread and invokes a callback when generateRandomNumbersterminated behind the scenes.

Any idea?

What about other web services?
