Java Forum / General / March 2007Running SDK from a USB key?
Hello, the kinds folks that replied to my Book Recommendations thread probably know what I'm up to here. I was just wondering whether you can run the J2SE SDK straight from a USB key without molesting the host machine. This is because I'm pondering 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 that installation would require some registry gubbins being installed on the host (Windows) machine?

I don't see any reason why the JDK shouldn't work from a flash drive. 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.

Some Linucex, like Fedora, use the alternatives mechanism. 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 On Mar 11, 7:32 pm, "Luc The Perverse" <sll_noSpamlicious_z_XX...@cc.usu.edu> wrote: > >> I don't know about running the JDK from a key . . but it is easy enough > >> to run Putty from a USB key ;) [quoted text clipped - 16 lines] > > :) Good idea. Looks like it would work then, which is good.

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 pondering though. Thanks, Gordy > ... I was just wondering whether you can run the J2SE SDK > straight from a USB key I'm curious; why don't you just try it? Or, if you did try it, and you encountered problems - why do you not mention this? And possibly even describe what you tried and what problems you encountered.

Good question, really. I don't have a lot of time, is the main reason. So I wanted to know the likelihood of it working before spending ages mucking about only to find it was never likely to work. I forgot to mention the machines run on Windows (it being a netcafe and all). Good point, though. Maybe I'm just lazy? ;) Gordy gordon.is.a.moron@gmail.com wrote on 11.03.2007 23:52: > Hello, the kinds folks that replied to my Book Recommendations thread > probably [quoted text clipped - 7 lines] > installation would require > some registry gubbins being installed on the host (Windows) machine? Yes. It's possible. 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.java Only 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.conf Thomas On Mar 13, 12:14 pm, Thomas Kellerer <TAAXADSCB...@spammotel.com> wrote: > gordon.is.a.mo...@gmail.com wrote on 11.03.2007 23:52: > [quoted text clipped - 27 lines] > > Thomas By running the JDK (I should have said using, really) I mean having the compiler as well as just the JRE, since I want to write and compile on the USB key. Not having applet/browser support would be fine though, since I'm not to worried about applets at the moment (is anyone?). As for using putty, probably not a good idea since the network connection here is horribly slow and the practicalities of running from my home PC with the time difference/distance etc. isn't really very sensible. Thanks everyone, though. Looks like it's do-able for what I want, anyway. Gordy Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
