Defining Attribute's Properties :

Control functionality and behavior :

Mandatory

Default value

Refresh on updateDefault UI representation :

Label

Tooltip.

Format mask.

Control type.

Set the attribute property see below.





How to add Field Level Validation :

Open JDeveloper select table, then go to attribute, then double click on any value . you can see below.

Declaration Validation :





Example : Employee Salary should be greater than 5000. Solution : Open JDeveloper select table, then go to attribute, then double click on any value .Click on Validation, Than click on New button. select Type, there is three tab available (Rule Definition, Validation Execution, Failure Handling )Select operator, Compare with , Enter Expression, Than click on ok button.

How to run this application :

Go to AppModule, right click than click on run link.. see below.





Out put :

Create View Objects Oracle ADF view objects are business components that collect data from the data source, shape that data for use by clients, and allow clients to change that data in the Oracle ADF Business Components cache.Step 1 : Right click on AppModule, select ADF Business Components, than select View object, after that click on Ok.





Step 2 : Enter then Name, Select the data source type. Then click on Next button.

Step 3 : Write Query Statement, for writing query click on Query builder button, then test the query and click on Next button.





Step 4 : Click on New button, then Enter Name, select Type Enter Value, Then click on Next button.







Step 7 : Check and set Attribute Settings, Then click on Next button.










Step 9 : Checked Application Module, Than click on Next button.

Step 10 : Then Click on Finish button.

After then run this application and see result, for run right click on AppModule and click on run. see below.





View Criteria - Dynamic where clause Define multiple query conditions

Apply selected condition at runtime

Enable further view object reusability

How to View Criteria :

Double Click on EmployeeView in Value object > select Query > then go to down and find view

criteria and click on plus icon. see below.Step 1 :





Step 2 : Enter Criteria Name, Click on Add Item button, Add attribute, set Operator, ser Operand, add Parameter, Then click on Ok button.

After click on Ok button you can see . after then click on Save button.

After that Run this application for see result :





Linking View Objects :A view link allows us to create a relationship between view objects. The relationship can be one-to-one, one-to-many, many-to-one, or many-to-many. The View Link Wizard and Editor lets us specify source and destination view objects, and links them using attributes selected. To create a view link, we first need to have all the underlying view objects in place.A view link is also like a Oracle Forms Block relation, that allows you to join two objects. Join Query -Define at view object query. -Can be updatable. Master/Detail -define with view links. -The derail item belongs to the master.

How to Create Linking View Objects :Step 1 : Go to Application, then go to Value object, then Click on " New View Object link " . see below.





Step 2: Enter Name , Then click on Next button.

Step 3 : Move Available Entity Objects, Then click on next button.





Step 4 : Choose specific field which you want and click on move button, Then click on next button.

Step 5 : Check attribute setting, Then Click on Next button.





Step 6 : Check Query and click on Next button.

Step 7 : Check Query, there is use join table.





Step 8 : Check bind Variables. Then click to Next button.






Step 10 : Mark Application Module and click on next button.

Step 11 : Check summary and click on Finish button.





After Run this application View result : See below.





List of ValuesIn this post i will continue to enhance my previous post’s Employee Form and create my first List of Values (LOV) in Oracle ADF Form. Creation of LOV in ADF is as simple as in Oracle Forms. In this post i am going to create LOV for Department and Job entities. Do the following steps to create LOV in ADF.1) Add Departments and Jobs Entities2) Add View Objects for Departments and Jobs LOVs3) Create LOVs4) Finally Link LOVs to JSF Page

Define at the attribute level.

Gets list from another view object.

Define type of list and list behavior.

How to add List of Values :

Step 1 : Go to application, select Any value object, click on Attribute, go to down and click on this icon.





Step 2 : Enter the list of Values Name, Select List data source, set list attribute, set UI Hints, Then click on O button.

After that run this application .





Define the Data Model for the Application Module :Associated with the root Application Module is the Transaction object, which provides this transaction context. From any (root or nested) Application Module, the user can retrieve the transaction object through a call to getTransaction(). In reality, getTransaction() first locates the root Application Module and then returns the transaction object from it.

How To open Data Model for the Application Module :

Open Apple action, Double click on AppModule , then select Data Model.





ADF Business Components : XML and Java.

ADF Business Components and JDeveloper simplify the development, delivery, and customization of business applications for the Java EE platform. With ADF Business Components, developers aren't required to write the application infrastructure code required by the typical Java EE application to:

Connect to the database

Retrieve data

Lock database records

Manage transactions

ADF BC uses XML metadata to describe the objects. By default there are no java files created. In many cases you don't need java files. However if you want more complex logic you'll put that ina java file overriding default behavior. You can create java files for EO, VO and AM.

Adding Logic to your Entity Object : The Impl file is the one you all mostly use Then choose which default method to create. You only need to create the one you want to override.

How to Add Logic to your Entity Object :

Go to Application Then Go to Entity Object and Double click on any table, Then Select Java(given

right side screen) then click on Edit icon. See below.Step 1:





Step 2 : Checked Generate Entity Object class.

Step 3 : Click on Entity Object Class.

Step 4 : On Source page right click , Then select Source > Override Methods, see below. for adding override method.





Step 5 : For Example : create remove Method, for create Remove method select Remove() method thenclick on Ok button. you can see below.

Step 6 : Write here code for print message .





Step 7 : After that run this application and see result.





Finding Hook-Points :- Use Source > Override Methods to locate an event you want to inject code into You have Access to :

set/get for attributes

Transaction events

Creation /remove events

DML events- Similar to Oracle Forms Triggers.

Exposing Your business Services to Other Systems : - Create SCA/SDO interfaces to business services declaratively. - Automates creation of : - java interface : Define the service. - EJB 3.0 session bean : Implements the java interface. - WSDl file : describes the service's operations. - XML Schema Document(XSD) : Defines the service's data structures. - Integration with Oracle's SOA Suite.

How to Add Services Interface :

Go application > Then Go Value Object, Double click AppModule > Select Service

Interface(Available Right side), Then Click on Add Icon. see below.Step 1 : Select Value Object, Then Double Click on AppModule, Then Select Service Interface.

Step 2 : Enter web service name click on Next button.






Step 4 : Select Table, Checked check box which want to want then click on Next button.
