how to add third party rpc framework support to ensemble?

Hi

   My HIS System is a Microservice architecture base dubbo.  To call remote service must through dubbo rpc. 

But , I canot direct call his's dubbo service because ensemble cannot support dubbo protocol.

So I want to add support to ensemble.

where Can I start?

Does ensemble has low level interface like dll or linux so,  I can add dubbo support to the ensemble just by implementing these interfaces.

I known java Gateway maybe ok, but I want to direct not throught middle layer to do this.

Tks.
