How to share java desktop application to multiple users

[91E20]

Please help,
I have a Java desktop application but I want to share the application to multiple users on a local computer offline so that everyone can access the application but I don't know where the database should be position in the computer so I can connect it to the application.

Am using JavaDB (derby database) as the backend for the application or can you recommend and show me which database engine I should use for this purpose and how to do it....

I am not an expert but I did some research on this and here's what I found-Unlike Microsoft-based apps and Microsoft products,
Java is intended to be portable to ALL platforms and operating systems
-- providing the JVM (Java Virtual machine) has been ported to that particular OS and platform.

Since JVM is portable to all operating systems that run on even the smallest hardware configuration, with minimal support for I/O, etc., Java apps are universally portable and any java app should run on ANY platform or OS
unless the platform or OS deliberately does something to block it.

I'm not sure if the original post was about portability or cross-platform.
