If Hessian is Dead, what should one use instead?

Question

In the comments to this question: Testing Hessian remoting-servlet.xml

Skaffman labeled Hessian a dead duck. So question is: what to use as a replacement.

Criteria for evaluation are:

• a drop in replacement would be cool
• should allow simple coding against interfaces
• no code generation as a separate build step
• reasonable efficient considering network bandwidth
• not a dead duck

Important update:

• http based

Answer 1

I'd probably use either Spring http invoker, hoping that the backing by the large spring ecosystem helps. It also looks like Hessian and http invoker should be easily exchangable.
