Hi,
I'm using portable Java (jPortable) on to launch portable Java applications from the jPort http://jwork.org/jport/ project. I want to use my USB with jPort on Mac/Linux. How can I force my Java to figure it out the platform? It seems jPort applications are fully multiplatform (since Java), while jPortable Java installation is platform dependent (i.e. runs on Windows). jPort desktop assumes that Java VM is not portable and is already pre-installed on the host computer.

It would be nice to have your apps available regardless what platform you're sitting in front of. Too bad jPort is not free or open source. They only have 15 registered users. If you are registered there, then you should contact them in their forum or send them an email asking for assistance.

If Wine is installed on the linux and mac machines, then many of the portable apps here will work. I'm not sure if the portable java does or not. Although if you can install Wine, you might as well just install Java there.
Otherwise, keep your PortableApps.com platform on the same drive with
PortableLinuxApps and OSXPortableApps. Many of the same apps are available on each platform. Perhaps they will come out with their own portable java and solve your issue, or you can seek help for those platforms on their forums.

Alternately, you could look into using a web based OS. Most of them are in their infancy, but they should get better as time goes on. I used Glide OS for a while. It was free, came with 30gb online storage and a decent array of web based apps: word processor, calculator, music player, spreadsheet, some social media stuff and others i can't remember.
A web based operating system can be accessed from any platform, be it windows, mac or linux, etc, so long as there is an internet connection and a web browser. It's like having a desktop inside your browser window. Many of them will sync up to your cloud storage as well.
Check out universeos.org for an example. You can mess around with it [use their music player (player button on bottom) while you read about the project (start>reader) or their terms of service ("terms" just above sign up button, also connects into the wiki) and also resize windows] without having to sign up or register. Best part is it is free and open source.

Sorry for the long answer; hope you find a solution to your problem.
