You create a new ADF Faces page called emp.jsрх and bind some data controls to that page. You notice a
file called empPageDef.xml. What is this file for? (Choose the best answer.)
A.
It is the page definition that contains the XML representation of the page layout and the components on that
page.
B.
It is a template file into which you can write any managed bean code.
C.
It is the page template definition file that represents the chosen quick start layout.
D.
It is the file that contains the definition of the bindings to your data-bound components.
E.
It defines the binding context for all pages in your application.
Explanation:
The pageNamePageDef.xml files are created each time you insert a databound component into a web page
using the Data Controls Palette or Structure window. These XML files define the Oracle ADF binding container
for each web page in the application. The binding container provides access to the bindings within the page.
You will have one XML file for each databound web page.
