What is Java, and what is a JAR file?
Last Updated 3 months ago

Java is a cross-platform programming environment that allows us to write only one version of our Manager application, and have it run on the Windows, Linux and MacOSX operating systems.

Our Manager applications (eg Spatial Manager, Spatial Dual Manager, Motus Manager etc) are generally supplied to you as a JAR file - you can think of the JAR as the container for the application.

Your computer system must have Java installed before you can run our Manager applications. If you are not developing your own Java application then you will only need to install the Java SE Runtime Environment (JRE). This can be downloaded from here: JRE download link.

If you are developing your own Java application (using our SDK for example) you will need to download the Java SE Development Kit (JDK). This can be downloaded from here: JDK download link.

It is very important that you download the correct version for your operating system: 32-bit Java should only be used on 32-bit operating systems, and 64-bit Java should only be used on 64-bit operating systems.

Once you have downloaded Java and completed the installation, you should be able to start the Manager application for your Advanced Navigation product. Windows users can simply double-click on the Manager icon. Mac and Linux users will need to start the application from a command line, for example:

java -jar SpatialManager.jar
