Without Installation (portable)
Portable
applications
have some advantages from a mobility point of view: you don't need to
install them and you can carry both the application and the program data
with you on an USB flash drive for example.
Program on an USB
flash drive, the JRE from the system
Download
nc-2.0.0.zip and
extract
the file using your preferred unzip-application to a
new
folder.
Hint: Since Windows XP
you can have a look into a .zip file using the Windows-Explorer, however
that view is just virtual, i. e. the files are being listet by the
Windows-Explorer, but they are not extracted. The files can be extracted by
selecting all files and moving the files to a new folder. Alternatively you
can use a different unzip program such as the free
7-zip.
In order to read and save the user properties in the program folder and not
in the user folder, call
nc-portable.jar
rather than nc.jar.
Execute
in
<myapp>/bin |
User
Properties are stored ... |
nc.jar |
on GNU/Linux and Unix in the
home directory called
$HOME/.NumericalChameleon
on Windows in the user directory called
%USERPROFILE%\.NumericalChameleon |
nc-portable.jar |
in the applicatoin folder
<myapp>/bin/.NumericalChameleon |
By default, the JRE on the computer system is used. The usage of a JRE
on the system has significant performance advantages, however it requires a
pre-installed JRE on the system. If you don't have a JRE installed yet,
please get one for free from
java.com.
Both program and JRE
on an USB flash drive
If you want to load not only the program, but also the JRE from your
external device, such as an USB flash drive, it is required to copy both the
program and the JRE on the external device and to launch the actual program
using the JRE which has been stored on the device. Dependend on the data
transfer speed between host computer and external device, it could
cause a decrease in performance, because not only the program, but also the
JRE must be tranferred from the USB-Stick to the memory of the computer.
Anyway, if you have the requirement to load the NC using that route, you can
download the bundle which has been provided here. Please just extract the
.zip file and copy the content on an (preferable empty) USB flash drive.
Launch the executable that is suitable for your operating system.

Notes:
Since the JREs on an external device cannot be updated automatically,
you should update the JREs manually from time to time. The actual JREs for
the operating systems are stored in a subfolder with a prefix called "jre".
If your external device is a FAT-32 formatted volume and the mount options
for the partition don't allow executing scripts and binaries (for example if
the showexec mount option flag is set) you can start the script on the
command line by entering "bash nc-portable".
