5. ADF IN LARRY‟S KEYNOTE
ON ORACLE OPEN WORLD 2009 AND 2010

6. THE TABLE
• ADF Faces
Rich Table (& Panel Collection)
– Displays ADF Model data bound collection, bean array,
List, ResultSet, RowSet and more
– Dynamic Table Configuration & Change Persistence
• Rearrange, resize, hide/show columns, freeze columns
– Post-load or Lazy Data Fetch
– Fetch data rows upon scroll
– Filter & Sort
– Read-Only and Click-to-edit
– [single or multiple] Row and Column Selection
– Header, Footer, Column Grouping, DetailStamp
– Many, many predefined facets
– Export data set, Email & Print mode

7. ACTIVE ROW KEY
• Property on table that is „click to edit‟
• EL expression that resolves to the primary key of the
row that should be displayed as editable
– Table will scroll that row into view

19. JDEVELOPER GO TO SHORTCUTS
• Go to Class: CTRL -
• Go to File: CTRL ALT -
• Find usages: CTRL ALT u
– For class, method,
EO and VO Attribute, …

20. MORE BEST SHORT CUTS…
• CTRL Shift Space: parameter insight
• CTRL = : list of recently opened files
• CTRL Space: completion insight
• CTRL Space (2x): declaration insert
• CTRL /: selection commented
• CTRL Shift C:
copy file path to
Clipboard
• Alt Home :
select
file in „tree‟

21. DATA VISUALIZATION

22. THE RIGHT MOUSE CLICK
• ContextMenu client listener
and
Popup (menu and window)

23. POPUP MAGIC

24. EXAMPLE: ADDING FANCY
BALLOON HELP
• Create a popup with a noteWindow child to
contain the fancy
help content
• Add a showPopupBehavior tag to the inputText
that we want to add the help to

25. EXPRESSION LANGUAGE
• IoC: Injection of Value and Listener into page
• Dynamic, context sensitive behavior
• Extension points
– Custom Functions invoked from EL
– Integration of Spring Beans
– Custom EL Resolver
• To resolve values from property files, ….

CLIENT SERVER INTERACTIONS VV.

29. USE SETPROPERTYLISTENER
TO PUSH DATA TO THE SERVER
• The setPropertyListener will pass
from value to the to target
when type event occurs on parent
– A very simple way to inform the
server about an event and the data
associated with the event
– Supported types: action, focus,
poll, query, rangeChange, selection, sort, rowDisclosure,
valueChange and many more
<af:image id="removeFromSetImage“
source="/images/removeFromSet.png“
shortDesc="Remove from Shopping Basket"/>
<af:setPropertyListener from="#{item}“
to="#{shoppingBasket.itemToRemove}"
type="action"/>
</af:commandLink>

30. SERVERLISTENER FOR CUSTOM AJAX
(BACKGROUND CLIENT TO SERVER
PUSH)
• A serverListener associates a
server side method with a
client side custom event
– This allows JavaScript functions
to call a server side method by queuing an event
– A custom event carries a payload

31. ADF ACTIVE DATA SERVICE –
SERVER PUSH TO CLIENT
• Push: server sends messages to client
• ADF Active Data Service enables UI components to
be „automatically refreshed‟ when server side events
occur
• Active UI Components include Table, Image,
OutputText, DVT Components
– Based on BAM Data Control
– Based on Custom Beans
that extend ActiveAdapter
• Nudge: push-to-refresh
• Note: client-2-client push
can easily be implemented
as client-to-server-followed-
by-server-to-client push
Web Browser
JEE Application Server

32. AUTO-PPR FOR IMMEDIATE REFRESH OF
DATA BOUND COMPONENTS
• To have ADF automatically refresh
data bound components when underlying
value binding has changed its value
• Set changeEventPolicy=ppr on iterator
– Refresh as piggy back on any request cycle
– No partialTriggers attribute required!

34. THE “HISTORY” FEATURE IN JDEVELOPER
• Quick comparison of file with previous states
– Can leverage Source Code Control system
(Subversion, CVS) but also maintains local file history
– The compare feature is ‘XML aware’
• Revert to a previous state of a file

35. MARRYING FORMS AND ADF TOGETHER –
MIGRATE WITH (i/o FROM) FORMS TO ADF
• OraFormsFaces leveraging the JavaScript-Applet
bridge for two-way event exchange

36. ADF BC PROPERTIES

37. LIBRARY PRIVATE

38. JAVA AND JEE
• ADF is a framework on top of Java, JEE and JVM
• Anything that is/extends/runs on one of these is
potentially usable with and relevant for ADF
• Zillion frameworks and libraries
– iText (PDF), Apache POI (Excel), Jasper Reports, BIRT
– Spring (IoC, AOP, Acegi/Security, Social, ..)
– Apache Commons, Google Collections, Joda Time
• Software Engineering
– Test (Junit, EasyMock), build (Ant, Maven), check/QA
(FindBugs, CheckStyle, Sonar),
• JEE facilities in WLS including JMS, WS* & RS, JMX…
• Dynamic JVM languages: Groovy, Scala, JRuby, …
• Java 7 SE and beyond
• Java FX?

39. PREPARE SESSION
• Before any other database communication is
performed during the processing of a request …
• ADF BC will execute the prepareSession() method that
you can override in ApplicationModuleImpl
• This is the perfect place to
– Reset package state
– Set application and client info
– Set application context
• User details, current session
context, view filter conditions
(real or poor man VPD)
– Fetch any events published
inside the database

40. CHALLENGE
• Create a Sliding Tile puzzle that tiles up an image in a
configurable number of tiles
• Using drag and drop, the user can reassemble the
image

41. STEPS
• Create Servlet that produces tiles from a JPEG
image
– Parameters: image name, tile factor, x and y
• Create PanelDashboard with panelBoxes with
richImage components
– That request their source from the servlet
corresponding to their position in the grid
• Bind the PanelDashboard and dynamically create
the panelBox components
• Allow user to set the tile factor and choose the
image
– Use a Carousel for image selection

45. PROGRAMMATIC VIEW OBJECT
• It walks, talks and looks like a „regular‟ View Object
– (regular being based on Entity Objects or SQL Query)
• But it is entirely fueled by custom written overridden
Java methods – possibly without database connection
– A bit like a View with Instead Of trigger – against a
Collection based Table Function and PL/SQL API
• Programmatic View Objects can be used as normal in
a Data Control for binding ADF Faces components
• Normal rich declarative ADF BC data binding can be
provided to UI developers for data sources such as
– WebService, JMS Queue, Memory Grid, Document
Management System, Email, cross session data, …
• Note: with the evolution of the Bean Data Control,
some of the use cases will fade away

46. THE ROOT OF AJAX
Suggestions

47. AUTO SUGGESTIONS
• User is entering a field
– As she types characters,
suggestions can be
presented for what the full entry should read
• Based on a list of allowable values, based on
previous (popular) entries or anything really
– User can pick a suggestion for ‘short-cut typing’
• Auto suggestions can be model-driven (declarative) or
custom
– And can do things beyond plain list based suggestions

48. INTRO
• Google Suggest set off the AJAX hype in anger
• Many implementations for a „suggestions‟ feature
in ADF 10g and 11g have been created
– Using custom JavaScript or libraries like Jquery
• With PS1, ADF 11g introduced a native
component for „auto suggestions‟
– The <af:autoSuggestBehavior> component, to be
included in inputText or inputListOfValues or
inputComboboxListOfValues

49. MODEL DRIVEN SUGGESTIONS
• The suggestions can be derived declaratively
from List of Values reference on a VO Attribute
• Steps:
– On ViewObject
• Create ViewAccessor (for list values)
• Create List of Values for Attribute
• Link LoV to ViewAccessor
– In Page
• Add InputListOfValues component based on attribute
• Add af:autoSuggestBehavior with suggestions based on
List of Values Binding’s suggestedItems

50. IN PAGE:

51. CUSTOM SUGGESTIONS
• Auto Suggestions can be provided by managed
bean that implements signature:
– List getSuggestions( String currentValue)
• And the List returned is really List<SelectItem>
• Potential use cases
– Based on some (application wide) cached
collection (of previously entered ?) values
– Retrieve values from WebService, file, …
– Use common abbreviations, codes
• Country code, airport
– Show translations in other languages

52. STATIC LIST OF COUNTRIES
Suggestions

53. SUGGESTIONS … OR?
• Suggested Values do not need to be suggestions in a
very literal sense
– What you see may not be what you get
– The SelectItem as a label (WYS) and a value (ISWYG)
• Examples:
– Add words to field instead of replacing value
– Perform selected
operation on value
– Show an updated
indicator based
on the value

54. PAGE TEMPLATE
• Turns page layout inside out:
– the page references the template
– the page template determines the overall structure
– the page provides the content for the designated areas
in the template (through the facets)
• Can be dynamically, context-sensitively selected using
an EL expression
• Can also be used for areas within a page
– With multiple page templates used within the same
page
– More an area template than a page template to define
UI Design Patterns
• Tree-with-Detail-Form, Table-and-Chart, Master-Form-
Detail-Table, Search block-Results table…

55. USING MULTIPLE PAGE TEMPLATES
• Two templates: mainpage and Table-Form template

56. OTHER PAGE CONSUMING THE
TEMPLATE(S)

57. CHANGING THE MICRO-TEMPLATE

58. SUMMARY
• Twinkle, twinkle little stars…
– #1 nugget
– #2 nugget
– #3 nugget
• Don‟t give up [too soon]
– There is more in ADF than meets the eye
– There is a world of Java/JEE to leverage
– There is a community to lean on
• Scan release notes and monitor blog-o-sphere for
valuable new (and re-discovered) nuggets
• Share! Yes, you too! Your findings are just as valuable.
– Participate in EMG and OTN Forum discussions, write
blog articles, present in conferences, …
