Does Thrift have asynchronous server method definitions for Java?

Question

I can connect the HsHaServer and Async client in Java and make everything work smoothly. The problem is that there is no asynchronous interface for truly asynchronous services. The service interface is similar to

public TSomeReposonse doStuff (TSomeParams parameters);

which requires me to lock inside doStuff until I get back TSomeResponse

There is Async.Iface

public void doStuff (parameters TSomeParams, AsyncMethodCallback [AsyncClient.doStuff_call]);

but it seems that this is only for the client side. There seems to be no way to pass the value to the callback. Am I right about this? If I need true server-side asynchrony, do I need to implement my own client / server with something like netty?

Thanks Andrew
