PL/SQL Web Cartridge A pl/sql procedure builds HTML tags, and the resultant HTML is shown on the browser.HTP Package procedures used.Called using SSWA Function of oracle eBiz SuiteExample: Some HRMS pages with PL/SQL cartridges

What is next …Oracle introduced a metadata concept in form of AK DeveloperItem properties like required/prompt/LOV etc became configurableThis meta data was stored in AK% tables. Reduced the programming effort to make minor changes

Disadvantages Both static/dynamic Content & validations were programmed within the PL/SQL. Presentation and data were within the same layerEven the simplest possible change required changes to PL/SQL Code

OAF EvaluationPL/SQL HTML

[email protected]

AK Developer with PL/SQL and other technologies In AK Developer Regions and Region Items can be defined using Screens. Important tables in AK Developer are AK_REGIONS and AK_REGION_ITEMS. “AK Developer” separates Data Layer from Presentation Layer. Regions within the screen and their fields can be defined using AK Developer.Examples : iProc Pages , HRMS pages

AK Developer Customizations Modify Fields Properties like Prompt, Required , Rendered , Enable DFF etc.,

OAF EvaluationAK Developer

Disadvantages of using AK DeveloperAK Developer changes are not upgrade safeAK Developer is standalone and is not integrated with jDeveloper, No IDEAK Developer Shared Regions changes are globally reflectedVery limited number of item styles were supportedAK is a proprietary technology

What is next …AK Developer is added with AK_CUSTOM% tables to store personalization to make AK developer upgrade safeOracle Applications Framework introduced to address IDE issue

[email protected]

OA FrameworkOA Framework is a combination of XML, Java and Meta Data ServiceOA Framework is a IDE thru JDeveloperOA Framework is WebUI developed using XML and then loaded to MDSOA Framework using MVC architecture OA Framework Highly extensible architectureUsing OA Framework •We can create custom pages•We can personalize existing pages•We can extend existing pages

DisadvantagesWYSWUG is not availableNo drag and drop provided as other standard IDE.Too much of code and too many steps for simple tasks.MDS is a propitiatory, Not an open standard.

What is next …Fusion ! ADF !!!

Now …Welcome To Oracle Application Framework

OAF IntroductionMVC Architecture

MVC ArchitectureM- Model Layer – Database ObjectsV - View Layer – Web User InterfaceC – Control Layer – Code Layer responds to WebUI eventsWidely used in webpage delvelopment

[email protected]

OAF IntroductionOAF Components & Onion architecture

M- Model Layer–(BC4J)Business Components for Java Objects (Server)•Entity Object (EO) = Oracle SQL Table•View Object (VO) = Oracle SQL Query •Association Object (AO) = Relations between EO,VO,AO•Application Module (AM) = Library [Access to EO,VO,AO]

V - View Layer – Web User Interface (UIX)UI XML Components (WebUI)•Page (PG) = Canvas•Page Layout Region (PLRN) = Form •Region (RN) = Block•Bean = Field

C – Control Layer – WebUI event listener (servlet)•Controller (CO) = Form Level Triggers [No access to EO,VO,AO]•processRequest method fires on page render.•processFormRequest method will be used to listen page events.•Controller will access AM code segments to perform business logic.

•Client Layers : UIX/webui and Controller •Business Layer : BC4J/server components

On Completion this presentation you should understand •External LOV region

•Attaching LOV region to a LOV bean of parent page•Dependant External LOV bean based on value passed form parent page

•Dependent LOV controller code

Understanding OAF Components : External LOV Exercise Goals

[email protected]

OAF IntroductionSearch Page LOV: Overview

Task • Modify homePG searchRN to have an LOV field to fetch employee ID from an independent

external Employee LOV and populate results to resultsRN based on employeeID returned

Design & Implementation• Extend Search page to have one pick list bean for department.• Create a new DeptVO for department picklist.• Create a new EmplovVO , we can use EMPVO if it is not designed to do any DML

operations.But it is recommended by oracle to create a seaprte VO for LOVs. • Create a OAF dependent EmployeeLOV region page for employee LOV to show selected

department employees.• Create EmployeeLOVCO to add where condition to EMPVO query• Set Properties of dept pick list bean to attach DeptVO values.• Change existing enameS textbean to LOV bean.• Set properties of enames as to attach EmployeeLOVRN to search page• No changes to results region Required as it is querying based on employee name already.
