This is probably a dumb question but I am new to Hessian (but not to
RMI) and I just want to be sure:
If I do:
ComputeService comp = (ComputeService)
factory.create(ComputeService.class, url);
Long result = comp.doBigCalculation(int 5000);
Then I assume that the int value 5000 is “searialized” via Hessian
and sent to the server and the BigCalculation method executes on the
compute server that hosts the implementation class of ComputeService
interface. Am I correct?
Correct.
Also is the HessianProxyFactory a light weight object to create and
throw away with every call or it is expensive to create and should I
use it as a singleton? In that case is it thread safe?
It's expected to be a singleton. The introspection of the classes and
types is cached by the factory, so it's better to keep it around. So,
it is thread safe.
