Thread: Run JDK from USB for BlueJ

Hello,

Im a bit new to this, I have a class requiring the use of BlueJ, I found the portable version on SourceForge and would like to have it run from the USB but as it requires the JDK. I am having very little success, I have tried installing it to the USB (Both BlueJ and JDK) created a bat file setting the path to the bin folder then tried running BlueJ but yet to no avail. The portable app works on any machine with the JDK installed, is there any way of redirecting paths via windows or the portable app itself so it looks for the Java libraries on the USB stick?

any help would be appreciated.

Thanks

I ended up getting the problem solved Thanks though. Not sure if people are concerned about my solution but if so so this is what i found:

Copy the lib, bin and jre folders of an installed JDK onto the USB drive, i.e. from C:\Program Files\Java\jdk1.5.0_10 to E:\jdk1.5.0_10
Copy the lib folder of your BlueJ installation onto the USB drive, i.e. from C:\BlueJ to E:\BlueJ
Create a file bluej.bat in the root of your USB drive, containing:

start jdk1.5.0_10\bin\javaw -jar BlueJ\lib\bluej.jar -bluej.userHome=home

The last bit forces the user's BlueJ home to be on the USB drive in the folder "home", which will be created if necessary.
If you want running BlueJ to be offered as part of the USB drive's autorun options, create a file called autorun.inf in the root of the containing the following:

[autorun]
open=bluej.bat
icon=bluej.ico
ACTION = Launch BlueJ-on-a-Stick

Moved. Thanks for updating with the solution.
