4. Installing Java JDK

To use JEUS, the Java SE Development Kit (JDK) must be installed.

Ensure that JDK 8, 11 or 17 is installed before installing JEUS. After installation, add the bin directory of the installed JDK to the environment variable PATH.

5. JEUS Licensing

A license key issued by TmaxSoft is required to use JEUS. A trial license is included with the version of JEUS installed by the installer by default. The license file is named 'license' and is in the 'JEUS_HOME/license' directory.

There are two license editions: Standard and Enterprise. They each have different features and license period.

To upgrade a license or to purchase a full license, contact a TmaxSoft sales representative or TmaxSoft directly. To use a license file, copy it to the 'JEUS_HOME/license' directory with the name of 'license'.

If the license file is not named 'license', rename it as 'license'.
