Java Runtime Environment Support for Arbortext Publishing Engine
Arbortext Publishing Engine does not ship with a Java Runtime Environment (JRE). Arbortext Publishing Engine, requires you to obtain a JRE from Oracle (www.java.com) or from Amazon and install it.
Arbortext Publishing Engine will work with Oracle Java 11 and Amazon Corretto 11.
The environment variable APTJAVAVMPATH specifies the path of the Java Runtime Environment installation. If this environment variable is set, it takes precedence over a set javavmpath command.
Tomcat Updated
Support for Tomcat has been updated to the 8.5.54 version.
Configuring Publishing Engine Post Installation
You must now configure the Arbortext Publishing Engine post installation. As of version 8.5-45 and later, the Tomcat server runs the SERVICE group as default instead of the SYSTEM group. This prevents the Arbortext Publishing Engine from successfully creating the Arbortext Editor subprocess. To enable creation of the Arbortext Editor subprocess, the SERVICE group requires permissions similar to the SYSTEM group. For more information, see “Configuring Publishing Engine Post Installation”, in the PTC Arbortext Help Center.
