Install Java. We recommend the OpenJDK Adoptium Temurin 8 or 11. This is the build of Open JDK that we test with across linux and windows.

Install the latest version and patch of Java We strongly recommend that you use the latest version of Java. These instructions will give you the latest patch. You can choose to install Java 8 or Java 11. Unless you are updating an existing installation of Java 8 to the latest patch, please install Java 11. If you are still on Java 8, you should consider updating to Java 11. Check on the controls in place in your organisation for moving to a different major version of a software package. However, in practice, moving from Java 8 to Java 11 is very unlikely to have an impact, and can be treated much as patching an existing version. |

Download and Install Java
On Windows
- From the Adoptium home page https://adoptium.net, select Termurin 8 or 11.
This download is equivalent to the Adopt Open JDK HotSpot build of Java for 64 bit architectures. - Click the Latest release button to download an installation package.
- Complete the installation process as directed by the package, accepting all defaults.
Optionally Set the Environment Variable
You can set a system envrionment variable JAVA_HOME if you wish. This can be useful if you have other applications that use Java. However, for the operation of PhixFlow itself, this is not needed, and most operators choose not to add this. Even if you do not set JAVA_HOME, Java programs that need to operate PhixFlow will be added to your path. I.e. you can call them from the command line by using the program name alone.
If you decide to set JAVA_HOME as a system envrionment variable, specify the base installation directory of Java, for example:
C:\Program Files\Eclipse Adoptium\jdk-8.0.312.7-hotspot
On Linux

Setting JAVA_HOME These instructions assume you do not have a version of Java already installed on your server. If you do, and you need to retain the version of Java you currently have, but this is not compatible with PhixFlow, you may need to set up different users to use different versions of Java. Typically this is done by setting the PATH environment variable for certain users. In these instructions JAVA_HOME is set for all users, but this is only a recommended option, and is not mandatory for the operation of PhixFlow. Where a java program is needed for PhixFlow, the documentation will either suggest that you supply the full path, or will refer to JAVA_HOME. If you do not set JAVA_HOME in this way, simply add the full path of the Java installation used by PhixFlow. |
