An Arbortext PE 应用程序 is custom code that runs in an Arbortext PE 子进程. An application is invoked by the Arbortext PE Request Manager in response to an HTTP request that specifies a class or function name. The purpose of the application is to process the request, generate an appropriate HTTP response, and return the response to the Arbortext PE Request Manager for transmission to the requesting client.

An Arbortext PE 应用程序 can use any of the AOM interfaces and ACL functions within an Arbortext PE 子进程 to manipulate documents. Because Arbortext PE 子进程 run in batch mode, you can only use interfaces or functions that are not related to the graphical user interface.
