2.2.3
Java
The latest version of the Java Runtime Environment is available from
www.java.com
.
You will need at least version 1.5.0, also known as Java 5.
2.2.4
RxTx Serial Drivers
Since Sun has removed support for serial drivers in Java, we use the open
source RxTx serial drivers.
This means that any client computer will require the files for RxTx.
We use version 2.1-7-r2, which is freely available from
www.rxtx.org
, and should
be provided with the softPanel application, in a directory called “RxTx”.
Inside the “RxTx” directory, you will find 2 files; one for each supported OS.
You should copy the file for your OS into the Installation Location shown below:
OS File Installation
Location
Windows rxtxSerial.dll
C:\Windows
Mac OS
librxtxSerial.jnilib
/Library/Java/Extensions
Users of Mac OS X may receive "PortInUseException" errors reported by the
RxTx drivers when attempting to open a COM Port.
In this case, you should ensure that your user account is granted permission to
use the COM Port, as described below.
2.2.5
Granting a user permission to open a COM Port in Mac OS X
N.B. In Mac OS X 10.5 (Leopard) and above the sudo commands below will
only work if the administrative user account has a non-empty password. (
This means that you must create a user account with a password to allow
installation. This is something that has recently been enforced by apple.)
