Hello all, I'm trying my hand at some ideas for a distributed Java application. At the moment, I'm considering a few possible solutions, but I'm not sure which would would best on FreeBSD. Here is a brief example of what I would like to try as a proof of concepts, based on a possible scenario: >>> We have data acquisition instruments with a controlling host computer. Imagine these in a lab, connected to the network. Somewhere else in the building, or perhaps even outside on the internet, is a server that has the proprietary processing algorithms that I could charge for by use. This web service would be exposed to all customers, regardless of platform. Other companies could even publish similar services as well. Now, imagine a scientist in their office in the first building. They have an applet which connects to the component controlling the instrument, gets the data, and sends it to the outside service for processing. <<< Would it make sense to make the instrument controller an EJB? How about the processing web service? Or should one or both be servlets? Would Jini be better here, or maybe just plain RMI? I'm trying to balance flexibility with performance. At this point, I'm not going to worry too much about the size of the data being transferred, though that could become an issue for large data acquisitions. jm -- My other computer is your Windows box.
