Oracle JET and ADF
BC REST Overview

5.
Oracle JET Overview
Oracle JET (JavaScript Extension Toolkit) – a modular toolkit based on modern JavaScript, CSS3, and
HTML5 design and development principles. Leverages popular Open-Source frameworks and adds
advanced functionality:
 Rich set of UI components
 Advanced two-way binding
 Advanced Routing System
 Smart Resource Management
 Validation framework
 Open Source

6.
ADF BC REST Overview
 ADF BC REST provides REST API that allows client application developers to interact with
exposed ADF BC objects
 ADF BC REST resources are backed by view object instances
 ADF BC REST allows to decide on the set of attributes to expose and actions to make available
 Supports standard CRUD operations and custom methods
 Data is shaped by REST resource backing view object instance, with the parent-child relationship
intact

7.
Use Case Overview

8.
ADF BC REST Functionality

9.
ADF BC REST CRUD
 Create, Read, Update and Delete operations are available by default

10.
ADF BC REST CRUD - POST
 Create with Content-Type as application/vnd.oracle.adf.resourceitem+json

11.
ADF BC REST CRUD - GET
 Fetching Collection and Filtering with Row Finder or Query with Criteria

12.
ADF BC REST CRUD - PATCH
 Update with Content-Type as application/vnd.oracle.adf.resourceitem+json

13.
ADF BC REST CRUD - DELETE
 Delete

14.
ADF BC REST CRUD Paging
 ADF BC REST supports retrieving collections with row set pagination using a GET method
 Example: http://server/demo/rest/1.0/Employees?offset=10&limit=10
 Limit – restricts the number of resources returned inside the resource collection
 Offset – defines a zero-based index into the collection. The index identifies the starting position
of the resource collection
 Set Access Mode = Range Paging in ADF BC VO. Range Size value will be updated on runtime
by Offset parameter

15.
ADF BC REST Master-Detail
 ADF BC REST supports retrieving nested resources using a GET method
 Example: http://server/demo/rest/1.0/Departments/50/child/Employees/120
Employee 120 from Department 50
 Example: http://server/demo/rest/11.0/Departments/50?expand=Employees
All Employees from Department 50

16.
ADF BC REST Basic Authentication
 Based on standard ADF Security. Make sure to specify applied HTTP methods for REST
Servlet

17.
ADF BC REST Advanced
 Retrieving LOV attribute values in the context of an existing resource item
 Querying a resource with a partial get using filtering to restrict attributes
 Fetching the resource collection with a row finder
 Returning just the data of the resource item or resource collection
 Returning the estimated count of resource items in a resource collection
 Executing a custom action defined by view object client interface
 Overriding the HTTP method to perform an update
 Making batch requests
 More: http://bit.ly/1X2OoMu

Oracle JET Rendering in ADF
 Use cases:
Render live data in ADF through JET island
Build public facing scalable sites with JET and back-office systems with ADF
 Possible to use JET island in ADF
 ADF timeout does not count activity in JET island
 Oracle statement: Should not mix ADF and JET, only in special use cases
 No official Oracle support

46.
Oracle JET Rendering in ADF
 Place JET UI code into ADF Fragment
