Portable Java Web Start Bobert - February 2, 2010 - 12:46pm
I have a .jnlp file that I want to make portable. It creates and uses a folder of data in the user's home folder, and also uses the java web start cache. Is there some way to use java portable to have it store both of these things on the flash drive? ( categories: )

-Duser.home
For Data, see -Duser.home. For the JWS cache, I'm not sure. If you can find a variable which is what it uses (like user.home or java.util.prefs or anything like those), and then put the command line argument -Dwhatever.it.is="$EXEDIR\Data\Thingy".

Emmm... Where do I change this variable?
There's no place like 127.0.0.1
In the command line

As in
javaws launcher.jnlp -Duser.home="$EXEDIR\Data"?

Yep
That's it. You should put the -D parameters before launcher.jnlp though. Also I'm not absolutely certain on the format; running javaws to see what it says I think you will need to do -JDuser.home="$EXEDIR\Data".

What about this...
I found this on the following page:
javaws.cfg.cache.dir=C:/path/to/cache to change the cache dir
http://lopica.sourceforge.net/faq.html#changecache
Is there some way I can do this, possibly with a paramater?

Try -JDjavaws.cfg.cache.dir="$EXEDIR\Data". It may work.
