Data Uploader requires Java SE Runtime Environment (JRE) version 6 (1.6.0) or higher from Sun Microsystems. The computer may already have the required Java runtime. To determine this open a command prompt or shell and type
java -version
If Java is installed, you may get a result like
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Server VM (build 16.0-b13, mixed mode)
If Java is not installed, or the version is older than 1.6.0, you must install version 1.6.0 or higher. You can download it from http://www.java.com for the platform the Data Uploader application will be deployed on.
Java on Linux
Set the environment variable JAVA_HOME to point to your install (e.g. /usr/local/java/jdk1.6.0_18). Also add $JAVA_HOME/bin to the execution path (PATH).
A good place to install Java is usr/local/java/{jdk-version}
If you put environment variables in /etc/profile, all users will have the environment variables set by default.
