The subprocessEnvironment Attribute
You can specify subprocessEnvironment to have Arbortext Publishing Engine set the environment variables of the Arbortext PE sub-processes. To ensure that Arbortext PE sub-processes have the expected values for environment variables, set them using the subprocessEnvironment parameter for each Arbortext PE sub-process pool in the e3config.xml.
If you are using the Tomcat servlet container, be aware that newer versions clear some environment variables, such as CLASSPATH, and then set them to values needed by Tomcat prior to starting the Tomcat servlet container.
Any other variables in the Arbortext Publishing Engine environment are passed to its Arbortext PE sub-processes unchanged.
