Hello, the kinds folks that replied to my Book Recommendations threadprobablyknow what I'm up to here. I was just wondering whether you can run theJ2SE SDKstraight from a USB key without molesting the host machine. This isbecause I'mpondering using it (and if possible a C++ equivalent) in a net cafe.Totally impractical,I know, but I'm curious as to if it would work. I suspect thatinstallation would requiresome registry gubbins being installed on the host (Windows) machine?Gordy

It wouldn't have file associations, paths or be installed into the browser, but it should just run. I switch between various JDKs on Linux simply by specifying the path to the binary I want to run each time.Tom Hawtin

Another alternative is to use a symlink or mountpoint (UNIX) or drive mapping (MS) to peg the JAVA_HOME directory to the USB - e.g.,   export JAVA_HOME=/media/EXTUSB/java/or   set JAVA_HOME=U:/java/, respectively.These will, of coure, fubar if the USB drive is disconnected, but that shouldn't be a real problem.-- Lew

And possibly even describe what you tried and what problems you encountered.

Although you've just given me an idea,I could in theory use my PC that is about 10k miles away as a server,but I'm not convinced that would be too practical. Worth ponderingthough.Thanks,Gordy

Looks like it would work then, which is good.Gordy

I don't have a lot of time, is the main reason.So I wanted to know the likelihood of it working before spending agesmucking about only to find it was never likely to work.I forgot to mention the machines run on Windows (it being a netcafeand all).Good point, though. Maybe I'm just lazy? ;)Gordy

Simply copy the installed JDK from another machine.The big question is: what do you understand with "running the JDK"?You can certainly run a Java based application without "installing" the JDK e.g.: e:\jdk\bin\java -jar MyApp.jar, assuming your USB Stick is e:\You can also compile a .java file using e:\jdk\bin\javac MyClass.javaOnly the browser plugin for running applets require a proper JDK installation. If you need to run Ant, make sure JAVA_HOME is defined to point to your USB stick.Setup of environment variables for your IDE depend on your IDE. NetBeans will run happily if you give it the path to the JDK on the commandline (--jdkhome) or through netbeans.confThomas

Nothaving applet/browser support would be fine though, since I'm not toworried aboutapplets at the moment (is anyone?).As for using putty, probably not a good idea since the networkconnection hereis horribly slow and the practicalities of running from my home PCwith thetime difference/distance etc. isn't really very sensible.Thanks everyone, though. Looks like it's do-able for what I want,anyway.Gordy
