If you use some client java-code(rmi-client?) to do the database updating in client, is it enough to put classes used in that apllication to client machine? and how to do an executable from those? making jar-file with main-class header pointing to the start-up class(static main String(..)). I remember reading that making jar-files executable requires putting them in some place in jre-directory tree? on is there some other possibility?
I don't understand your question. Are you asking if you can send a "message" to a remote machine to have it insert things into a database it keeps? I don't understand what you are asking about executables Chris
