A. protected void create(AttributeList attributeList) { super create(attnbuteList), setAttributelntemalC'SALARY", 0);]

C. protected void create(AttributeList attributeList) { super create(attributeList); setSalary(O); }

Correct Answer: A

Question 4

The EmployeesVO view object is based on the Employees table and includes a Deptld attribute.
However, Deptld is not really meaningful to the end user and so, for each employee returned by EmployeesVO. you need to show the correct DepartmentName, which comes from the Departments table and is referenced by the EmployeesVO Deptld attribute. How can you achieve this behavior by using the declarative features of ADF Business Components? (Choose the best answer.)

A. Add a transient attribute to EmployeesVO and set its value to select DepartmentName from Departments where Deptld = EmployeesView.Deptld

B. Create a database view to join the Departments and Employees tables and base the view object on that view.

C. Define that EmployeesVO is also based on the Departments entity object. Then select "Add attribute from entity" in the EmployeesVO view object and select DepartmentName from the Departments entity object.

D. Add a transient attribute called DepartmentName in the view object and, in the ViewRowlmpI class, override the getDepartmentName() accessor to: return (String) getAttributelnternal(DEPARTMENTNAME);

E. For the EmployeesVO view object, select the query and add WHERE Employees DEPARTMENTJD = Departments.DEPARTMENTJD

Correct Answer: A

Question 5

Consider the validation code in a Shipping entity object that is designed to ensure that the
date ordered is <= the date shipped.
public boolean validateDateShippedAfterDateOrderedQ {
Date DateShipped = getDateShipped();
Date DateOrdered = qetDateOrdered();
if (DateShipped != null && DateShipped.compareTo(DateOrdered) < 0){
return false;
}
return true;
}
Which entity object validation rule should you integrate this with'' (Choose the best answer)

A. method validator on the Shipping entity object

B. compare validator on the DateOrdered attribute

C. compare validator on the DateShipped attribute

D. method validator on the DateShipped attribute

E. range validator on the Shipping entity object

Correct Answer: B

Question 6

Which method must you override to ensure that messages are logged each time bind variable values are set in an application? (Choose the best answer.)

A. bindParametersForCollectionO method in the super-class of ViewObjectlmpI

B. bindParametersForCollection() method in any ViewObjectlmpI that uses bind variables

C. bindParametersForCollectionO method in the super-class of ApplicationModulelmpI

D. setBindVahables() method in any ViewObjectlmpI that uses bind variables

Correct Answer: A

Question 7

Consider the following code:
<af:inputTexl valueChangeListener="#{myBean.handleChange}r .../>
<af:commandButton actionListener= n#{myBean.doAction}" action="#
{myBean qetDestmation}" .../>
At run time, a user modifies the value in the af:inputText control, then presses afcommandButton
Assuming no errors are raised, which option represents the managed bean code invoked in the correct order1? (Choose the best answer.)

A. myBean handleChange, myBean doAction, myBean.qetDestination

B. myBean.handleChange, myBean.doAction

C. myBean.doAction, myBean handleChange, myBean.getDestination

D. myBean.doAction, myBean.handleChange

Correct Answer: B

Question 8

Which statement describes the Oracle implementation of model-view-controller (MVC)? (Choose the best answer.)

C. ADF Controller provides support for application tasks such as validation, state management, security, and business-process orchestration.

D. JSF Controller is the best choice for ADF Faces-based web applications because it enables you to break up an application's page flow into re-usable fli

Correct Answer: B

Question 9
