Introduction

PASOE (Progress Application Server for OpenEdge) is the runtime platform used by the SmartComponentLibrary to expose its OERA‑based Business Entities and Business Tasks as modern, HTTP-based services. Within the SmartComponentLibrary, PASOE is typically used to host the backend service layer and to provide RESTful endpoints for Business Entities (for example via the RestEntitiesWebHandler), enabling JSON/HTTP access from web, mobile, and third‑party applications. This allows you to deploy the same SmartComponentLibrary business logic behind desktop UIs, browser-based UIs, and external REST clients, all through a scalable, manageable PASOE application server.
