1. Installing Java

BellaDati requires Oracle's Java SE 8 platform to run. Refer to Supported Platforms for details on the Java platform versions that BellaDati supports. Oracle's JDK can be downloaded from Oracle's website.

Please be sure you are installing JDK with Server HotSpot, and not just JRE.

 

You can test whether you have the correct Java platform by running java -version:

~$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b18, mixed mode)

On recent Linux distributions, Oracle's JDK can be installed through a package manager, e.g. apt-get on Ubuntu.

2. Setting JAVA_HOME

Once the JDK is installed you need to set the JAVA_HOME environment variable pointing to the root directory of your JDK installation.

Some JDK installers set this automatically. You can type echo %JAVA_HOME% in a Windows command prompt or echo $JAVA_HOME in a Linux/UNIX console to verify. If the property hasn't been set, follow the steps below.

2.1 For Linux/Solaris

You can set the JAVA_HOME variable with the following command:

$ export JAVA_HOME=/path/to/jdk

Make sure this variable is automatically set after system starts (append it to the .profile).

2.2 For Windows

Windows users can specify environment variables in the System Properties->Environment Variables window.
