Install and Configure Java

Now that your Unanet Software has been installed, you can use OpenJDK or Oracle JDK (see System Requirements).  This is necessary because the Unanet Servlet is written in the JAVA language and runs in a Servlet Environment.  Please note that if you already have Java installed, you have the option of using it for your Unanet installation and may not need to complete this step.

The topics covered on this page include:


Obtain the JAVA Platform

The Java JDK (not the JRE) is used to support Java applications. See System Requirements for supported versions.

Unanet recommends that you use the most current version that is supported (including the most current updater).   This can be downloaded at Oracle following the links for "Java SE Downloads" (note: download the JDK latest update -- not the JRE).

Once Java installation completes, you'll need to set up the JAVA_HOME environment variable.

Variable Name: JAVA_HOME
Example Value: c:\program files\java\jdk11      (substituting your specific location and directory name)


Installing Java

After downloading Java SE, simply run the executable to install Java in the location you desire.  Further configuration of your Java Environment may be necessary depending on your individual requirements.

Note: Our Tuning Tips page contains more information on Java parameter tuning.

Step 5 -- Install/Configure the Servlet Engine

Once Java has been installed, you are ready to move on to Step 5 -- Installing and Configuring the Servlet Engine.  

While Unanet may work with a number of Servlet Engines, we currently have installation instruction for Tomcat only.
