Re: Integrating Hessian with UI

Well, the point in making it a single call to begin with was to reduce round
trips. The application is making these calls from across the internet,
converting it to a number of calls would greatly increase the transmission
time - especially if I wanted a small enough granularity to drive a progress
bar. Moreover, the single call is necessary so that the entire logical
transaction can occur within a single actual transaction on the server side.
I can see two possible solutions. One would be to supply Hessian with my own
input and output streams, if this were possible (maybe it is?). I would then
need to know how many bytes Hessian would transmit as the return value.
Then, I could just count the number of bytes transmitted and so drive a
progres bar.
The other solution would be to provide Hessian with my own factory, so that as
it instantiates each part of the return value I could determine its progress
and so drive the progress bar.
Is either of these options feasible, and if so, how do I approach implementing
this with Hessian?
