The Oracle Applications Platform

Redwood — Oracle’s Design System for Fusion Cloud

Oracle Redwood is Oracle’s next-generation user experience design system — a set of building blocks, components, and design templates that define the look, feel, and interaction patterns of all Oracle Fusion Cloud Applications. Every new Fusion module is built natively on the Oracle Applications Platform using the Redwood Design System.

Oracle EBS Extensions

Oracle Redwood is a set of building blocks, components, and design templates — the same UI resources Oracle uses to build Oracle Fusion Cloud Applications. Extensions built with Redwood components match the native Fusion look, feel, and accessibility standards exactly.

Oracle Applications Platform

The Oracle Applications Platform includes Oracle Visual Builder Studio and the Redwood Design System — and is available to Fusion Cloud customers to build their own extensions using the same resources Oracle’s own development teams use to build Fusion Cloud modules.

Integral — Not iFramed

Redwood Application Extensions are an integral part of the Fusion UI — not iFramed separate windows. They appear in Oracle Cloud Application menus, share Fusion authentication and authorisation, and are indistinguishable from delivered Fusion functionality to end users.
Two Development Modes

Express Mode and Advanced Mode — Choosing the Right Approach

Visual Builder Studio offers two modes for Redwood extensions. eAppSys selects the right mode based on the Fusion pillar, the complexity of the change, and what the business needs to achieve.

Express Mode — Functional Personalisation

  • Add, remove, and reorder fields on existing Redwood pages
  • Business Rules — set default values and validate field inputs
  • Display logic — show or hide fields, regions, and components based on conditions
  • Dynamic containers — rearrange and add content to predefined page areas
  • Customise layouts and component visibility at the site level
  • No code required — functional administrators can make changes directly

Advanced Mode — Developer Extensions

  • Create entirely new Redwood Application Extension pages within Fusion
  • Custom business objects and data models hosted within the Fusion environment
  • External REST API integrations — connect Redwood pages to external services
  • Custom action chains, event listeners, and JavaScript functions
  • Full VB Studio design-time — page templates, layouts, navigation flows
  • Embed new pages within existing Fusion menus with full SSO

Three Extension Patterns

How eAppSys Extends Oracle Fusion with Redwood

Oracle defines three extension patterns for Fusion Cloud Redwood applications. eAppSys delivers all three — selecting the appropriate pattern based on the use case and pillar.

1. Edit an Existing Redwood Page

  • Modify delivered Oracle Fusion Cloud Redwood pages — add, remove, reorder fields
  • Set business rules — field defaults, validation logic, and conditional display
  • Uses VB Studio Express Mode — accessible to functional administrators
  • Changes deployed directly to the Fusion instance via VB Studio publish
  • Available across HCM, SCM, Procurement, and selected ERP Redwood pages
  • No custom development license required — included with Fusion subscription

2. Create a New Redwood Application Extension

  • Build entirely new pages within the Oracle Fusion Cloud UI framework
  • New pages appear in Oracle Cloud Application menus — integral, not iFramed
  • Access Fusion REST APIs and custom business objects from within the extension
  • Same Fusion users, roles, and authorisation — single sign-on
  • Built using Redwood Design System components — matches native Fusion UI
  • Deployed via VB Studio CI/CD — Git, build pipeline, and Fusion environment mapping

3. New External Redwood Application

  • Build a standalone Redwood application embedded within Oracle Fusion Cloud
  • Hosted on the Visual Builder platform — own domain, own security model
  • Integrates with Fusion REST APIs via service catalog
  • Exposed as a menu option or custom tab within Oracle Cloud Applications
  • Can call external REST APIs from OCI services and third-party sources
  • Visual Builder Runtime licence required for standalone hosting
eAppSys Redwood Services

Four Redwood Development Service Areas

eAppSys delivers Oracle Redwood development across the full service lifecycle — from initial page extensions through to new Redwood applications with full CI/CD delivery.

Redwood Page Extensions

Express Mode customisation of existing Fusion Redwood pages — adding fields, setting business rules and validation, configuring display logic, and rearranging dynamic container layouts across HCM, SCM, ERP, and Procurement.

Redwood Application Extensions

Advanced Mode development of new Redwood Application Extension pages within Oracle Fusion Cloud — new functionality, custom business objects, external REST integrations, and complex application logic using the full VB Studio design-time environment.

VB Studio CI/CD for Redwood

eAppSys configures Visual Builder Studio for team development of Redwood extensions — Git repositories, build pipelines, workspace management, and automated deployment to Fusion development, test, and production instances.

REST & OCI Integration

eAppSys connects Redwood extensions to Oracle Fusion Cloud REST APIs, OCI AI services, and external data sources — using the Fusion REST proxy for secure authenticated calls and the VB Studio service catalog for Oracle business objects.

Common Questions

Frequently Asked Questions

What is Oracle Redwood?
Oracle Redwood is Oracle’s next-generation user experience design system — a set of building blocks, components, and design templates that define the look, feel, and interaction patterns of Oracle Fusion Cloud Applications. All new Oracle Fusion Cloud modules are built natively on the Oracle Applications Platform using the Redwood Design System — including HCM Journeys, CX Field Service, and ERP Touchless Expenses. Redwood delivers consumer-grade, responsive, and accessible user experiences across Oracle Fusion Cloud.
A Redwood Application Extension is a customisation or new application built using Oracle Visual Builder Studio that extends Oracle Fusion Cloud Redwood pages. Extensions can change and edit existing Redwood pages or create entirely new Redwood applications deployed with Oracle Fusion. Extensions are integral to the Fusion UI — not iFramed — share Fusion authentication and authorisation, and appear within the existing Fusion application menus as if delivered by Oracle.
The Oracle Applications Platform is the platform Oracle uses to develop Oracle Fusion Cloud Applications — and which Oracle has made available to Fusion customers for their own extensions. It includes Oracle Visual Builder Studio and the Oracle Redwood Design System. Using the Oracle Applications Platform, customers can: modify delivered Oracle Applications Redwood pages; create new Oracle Application pages; create new external applications embedded within Oracle Cloud Applications; and leverage the same security, roles, privileges, and functionality being used by Oracle Cloud Applications.
Express Mode is a simplified VB Studio interface for functional administrators — adding, removing, and reordering fields, setting business rules, and configuring display logic without writing code. Express Mode is supported by HCM, SCM, and Procurement. Advanced Mode exposes all VB Studio developer features — creating new pages, connecting to external REST services, custom JavaScript, and full application logic. Advanced Mode is available for ERP, CX, and standalone application extensions. HCM, SCM, and Procurement support Express Mode only.
eAppSys provides Oracle Redwood development across four areas: Redwood Page Extensions (Express Mode — field additions, business rules, display logic across HCM, SCM, and ERP); Redwood Application Extensions (Advanced Mode — new pages, custom data objects, external REST integrations); VB Studio CI/CD for Redwood (Git repositories, build pipelines, automated Fusion deployment); and REST and OCI Integration (Fusion REST APIs, OCI AI services, and external data source connectivity). Ongoing support via OracleCloudCare.
