Hi Amit, I still don't know much about your app and requirement, but what I can say:
a) you should stick to http rather than going to any other kind of RPC: http on port 80 is very well managed and ubiquitous over the whole Internet. If you go to something more "exotic", you risk getting blocked by firewall, being poorly managed by content caches or load balancers. You risk issues (hard to figure out and solve...) that you could simply avoid via sticking to http. b) If you go java to java, why don't you use standard java serialization rather than going to PB protocol ? The idea: you have java objects on both sides and you ship them back and force over http via standard java serialization (using class ObjectOutputStream for example). Is this helpful or do I miss something? regards didier On Feb 22, 7:03 am, Amit Pandey <amit.s...@gmail.com> wrote: > Hi Didier, > > Almost same requirement is mine.
