There are two methods available on how a user can download and install the Java Development Kit (JDK) on a Windows environment.
Install via the official Oracle JDK website
Java can be downloaded from the official Oracle JDK Downloads website here depending on the requirement of the end-user or organization.
Install via the OpenJDK binaries for an open-source and specific version of the JDK
Using the OpenJDK binaries edition to install the JDK will be free as it is open-source and not subject to any licensing complication with Oracle.
The OpenJDK binaries contains an extensive library of the previous versions of the OpenJDK available for downloading. Access to past versions might be required for an end-user due to development/product compatibility, or other technical requirements for development for the organization. Further information can be found here.
For Java applications to run, the user needs to set up a JAVA_HOME environment variable that will point to the Java installation directory. In addition, if the user wants to run Java commands from a command prompt they will need to set up the PATH environment variable to contain the Java bin directory.
When using Windows, the above parameters can be configured in the Environment Variables panel. Click on the Start button and type env to access this menu (Figure 1):
Figure 1 Environment Variables
Note: In this example, the installation directory is C:\Program Files\Java\jdk1.8.0_172
Click New... and enter PATH as the Variable name and the %JAVA_HOME%\bin as the Variable value before clicking OK (Figure 4):
Figure 4 New User Variable
Note: If a PATH variable already exists, add ;%JAVA_HOME%\bin at the end of the Variable name
To test the above configuration has been entered correctly, open a command prompt from the Start button, type java -version and press Enter. This should display the results below (Figure 6):
Figure 6 Results
The install will now be complete.
If the install fails, please contact the Symphony Support team at firstname.lastname@example.org and inform them that you are experiencing issues with a JDK install for Windows.
