Every Arbortext PE サブプロセス contains a Java object called the Arbortext PE アプリケーション Context. The Arbortext PE アプリケーション Context is responsible for loading and executing Arbortext PE アプリケーションs upon request from the Arbortext PE Request Manager. The Arbortext PE アプリケーション Context starts when the Arbortext PE サブプロセス launches. Before the Arbortext PE Request Manager asks an Arbortext PE サブプロセス to run an Arbortext PE アプリケーション, the Arbortext PE Request Manager passes parameter information to the Arbortext PE アプリケーション Context. The parameter information includes all global parameters defined in e3config.xml, plus all of the parameters defined for the Arbortext PE サブプロセス pool in which the Arbortext PE サブプロセス will run.

The Arbortext PE アプリケーション Context stores the parameter information it receives from the Arbortext PE Request Manager in an object called the Application Configuration. An instance of this object, which implements the Java class com.arbortext.e3.E3ApplicationConfig, is passed to the init method of every Arbortext PE アプリケーション written in Java. The information is also available to JavaScript, VBScript, and ACL applications, as described in later sections.
