OL IDE

What OL IDE is

An Eclipse-based design-time environment that generates Java SDK and API/service projects from legacy backends. Latest line: 5.2 (OpenLegacy Core 5.2.x).

Project types

• RPC SDK — program/function invoke with no UI (copybook, PCML, stored procedure, SOAP, …)
• Screens SDK — 3270/5250 terminal models and navigation when business logic lives in the screen layer
• Service / API project — REST or other endpoints that orchestrate one or more SDKs into a deployable microservice

Typical workflow

1. Download the installer from Downloads (signed in), then install the IDE (standalone or Eclipse plugin) and apply a license.
2. Create an SDK project and choose a connector.
3. Generate entities from source or a live backend; refine them in the entity editor.
4. Create or attach a service project, choose an endpoint, test, then package for deploy.
