It is used to deliver report to multiple emails, let it be your pay slips or PO’s or others.

1. Create rdf data model.
2. Register Executable.
3. Register Concurrent Program
4. Setup the temporary Working directory.
5. XML Bursting control File.
6. Create the rtf template.
7. Register Data definition.
8. Upload XML control file to data definition.
9. Register data template.
10. Move rdf file to registered TOP.
11. Move rtf file to tmp directory.
12. Attach the concurrent program to request group.
13. Attach another XML Publisher Report Bursting Program concurrent program to same request group.
14. Run the report.
15. Errors and solutions

1. Create rdf data model.

Query:

select full_name, person_id,email_address,EFFECTIVE_START_DATE,EFFECTIVE_END_DATE

from per_people_x ppx

where email_address is not null

and employee_number in ('9213','9214','9215')

and business_group_id = :p_business_group_id

and rownum < 5

function AfterReport return boolean is

 req_id number;

begin

            req_id := FND_REQUEST.SUBMIT_REQUEST(

                application =>'XDO',

Errors and Solution:

If the xml report run is normal and Bursting concurrent Program ends with Error then check the patch number Patch 9501440:R12.XDO.B is applied or not.

 

SELECT patch_name
FROM   apps.ad_applied_patches
WHERE patch_name LIKE '%9501440%'

 

Reference: Doc ID 1276845.

If both programs ends normal, but no email then need to check with the network and database team regarding server and port which we configured in the xml control file.

Errors and Solution:

1. Don’t forget to commit the transactions in the Step3.

2. If you get the error in the HR as “ Error: run the script $PER_TOP/admin/sql/hrahkpar.sql”

Solution: Delete the user hook , commit, create again using Step3.

3. If updated the package, procedure delete again the user hook and recreate again.

4. No need to bounce the apache or middle just run the Step3 of 3rd point.

26. OAF Storing Images into Database

1. In database table create column datatype as Blob
2. In VO Attribute based on EO Check the attribute type is BlobDomain
3. Create Item in Region:
itemStyle : MessageFileUpload.
 DataType : Blob 

25. OAF Multi Language text (Ex: Arabic, French)

In our Company we have Both English and Arabic Instances for Oracle Apps R12.1.3
So If we create any Custom OAF Page we need to add the Arabic Labels. Let see how to add them.
Example:
Page:ResultBaseSearchPG
Step1: Create folder under D: Drive as Temp
Step2: run the below command in cmd.
D:\JDev_Home\jdevbin\oaext\bin\xliffextract /xxresultbasesearch/oracle/apps/po/resultbasesearchprj/webui/ResultBaseSearchPG
-root D:\JDev_Home\jdevhome\jdev\myprojects
-source db -username apps -password apps
-dbconnection "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.10.10)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=VIS)))"
-languages ar-AE
-mmd_dir D:\JDev_Home\jdevbin\oaext\config\mmd
-xliff_dir D:\Temp\XLIF\XXTFRMSLAUC19

below is same as above but in single line to directly paste in cmd prompt:
D:\JDev_Home\jdevbin\oaext\bin\xliffextract /xxffrd/oracle/apps/xxcust/ffrd/webui/ResultBaseSearchPG -root D:\JDev_Home\jdevhome\jdev\myprojects  -source db -username apps -password apps  -dbconnection "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.10.10)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=VIS)))"  -languages ar-AE  -mmd_dir D:\JDev_Home\jdevbin\oaext\config\mmd  -xliff_dir D:\Temp\XLIF\ResultBaseSearchPGAR

Step3: The above command will create xlf file under D:\Temp\XLIF\ResultBaseSearchPGAR
Open the xlf file> change the text for all the <target>
Let say:
Before:
<source>FileNumber</source>
           <target>FileNumber</target>
           <prop-group name="ora_untranslatable">
              <prop prop-type="tagName">messageStyledText</prop>
              <prop prop-type="attributeName">prompt</prop>
After Mofication:

<source>FileNumber</source>
           <target>رقم الملف</target>
           <prop-group name="ora_untranslatable">
              <prop prop-type="tagName">messageStyledText</prop>
              <prop prop-type="attributeName">prompt</prop>

-- It was before FileNumber in <target> we changed to our Arabic Language and save it.

Step4:
Importing the Translation in to Apps:
D:\JDev_Home\jdevbin\oaext\bin\xliffimport -username apps -password apps -dbconnection "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.10.10)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=VIS)))" D:\Temp\XLIF\ResultBaseSearchPGAR\ar-AE\ResultBaseSearchPG.xlf

Step5: For export and import of translations no information will be shown in the command prompt unless there is error.

Step6: Just login to apps change the instance to arabic and check it.

24. OAF Interview Questions

OAF Interview Questions – Part1

1. What is an EO?
a. Map to a database table or other data source
b. Each entity object instance represents a single row
c. Contains attributes representing database columns
d. Fundamental BC4J object through which all inserts/updates/deletes interact with the database
e. Central point for business logic and validation related to a table
f. Encapsulates attribute-level and entity-level validation logic
g. Can contain custom business methods
2. What is a VO?
a. Represent a query result
b. Are used for joining, filtering, projecting, and sorting your business data
c. Can be based on any number of entity objects
d. Can also be constructed from a SQL statement
3. What are the methods in controller?
ProcessRequest, ProcessformData and processformrequest
ProcessRequest : is called when the page is requested for the first time from the server.
ProcessFormRequest : is called when some event occurs on the page
ProcessformData(not visible). : Used to capture Data from the form fields which the user has entered and post it into Model Layer.
4. What is a Controller?
Controller is the java file and can be associated to a complete OAF page or to a specific region.
There are several tasks you will do routinely in your code.
Handle button press and other events
Automatic queries
Dynamic WHERE clauses
Commits
JSP Forwards
The logic for accomplishing all these tasks is written in controller
5. When is the processRequest method called?
PR method is called when the page is getting rendered onto the screen
6. When is processFormRequest method called?
PFR method is called when we perform some action on the screen like click of submit button or click on lov
7. What is extension?
Extension is when you take an already existing component ex an OAF page or a region and then add some more functionality to it without disturbing the original functionality.
8. What is personalization?
Oracle Apps Framework has an OA Personalization Framework associated with it so that you can personalize any OAF page in an Oracle E-business Suite application without changing the basic or underlying code of that OA Framework page, Oracle Application Framework makes it very easy to personalize the appearance of the page or even the personalization of data displayed on to an OA Framework page.
9. What are levels of personalization?
1. Function Level
2. Localization Level
3. Site Level
4. Organization Level
5. Responsibility Level
6. Admin-Seeded User Level
7. Portlet Level
8. User Level
10) What is BC4J?
Business Components for Java is JDeveloper’s programming framework for building multitier database applications from reusable business components. These applications typically consist of:
• A client-side user interface written in Java and/or HTML.
• One or more business logic tier components that provide business logic and views of business objects.
• Tables on the database server that store the underlying data.
11.What are all the components of BC4J?
Following are the components of BC4J:
• Entity Object – EO encapsulates the business logic and rules. EO’s are used for Inserting, Updating and Deleting data from the database table. E0 is also used for validating the records across the applications.
• View Object – View object encapsulates the database query. It is used for selecting data. It provides iteration over a query result set. VO’s are primarily based on EO’s. It can be used on multiple EO’s if the UI is for update.
• Application Module – Application Modules serve as containers for related BC4J components. The pages are related by participating in the same task. It also defines the logical data model and business methods needed.
12) What is an EO?
EO encapsulates the business logic and rules.EO’s are used for Inserting, Updating and Deleting data. This is used for validating across the applications. We can also link to other EO’s and create a Association object.
13) What is an VO?
View object encapsulates the database query. It is used for selecting data. It provides iteration over a query result set.VO’s are primarily based on Eo’s. It can be used on multiple EO’s if the UI is for update. It provides a single point of contact for getting and setting entity object values. It can be linked together to form View Links.
14) What is an AO?
An association object is created where we link EO’s. For example take the search page where we link the same EO to form a association between the manager and employee. Every employee should have a manager associated. But if it President then no there is no manager associated. This is a perfect example to understand the AO.
15) What is an VL?
A view link is an active link between view links. A view link can be created by providing the source and destination views and source and destination attributes. There are two modes of View link operation that can be performed. A document and Master/Detail operation.
16). What is UIX?
UIX is an extensible, J2EE-based framework for building web applications. It is based on the Model-View-Controller (MVC) design pattern, which provides the foundation for building scalable enterprise web applications.
17). Where the VO is located in the MVC architecture?
VO is located in the View Layer in MVC which is responsible for presenting the data to the user.
18) Which package should include EO and AO.
The EO and AO will be present in the schema.server package.
19) What is the difference between inline lov and external lov.
Inline lov is a lov which is used only for that particular page for which it was created and cannot be used by any other page.
External lov is a common lov which can be used by any page. It is a common component for any page to use it. It can be used by giving the full path of the lov in the properties section “External LOV” of the item.
20) What is a Javabean?
JavaBeans is an object-oriented programming interface that lets you build re-useable applications or program building blocks called components that can be deployed in a network on any major operating system platform.
21) What is query Bean?
QueryBean is used to execute and return the results of a query on behalf of the QueryPortlet application.
22) What is the difference between autocustomization criteria and result based search?
Results based search generates search items automatically based on the columns on the results table.
In Autocustomization search we need to set what all fields are required to display as a search criteria.
23) What is MDS?
MDS is MetaData Service. When a web page is broken into small units like buttons,fields etc they are stored in a database. These are not stored as binary files but as data in tables. The data are present in JDR tables. MDS provides service to store & return page definitions. MDS collects those definitions in components/fields in a meaningful manner to build a page.
24) What is XML?
XML is a markup language for documents containing structured information.
Structured information contains both content (words, pictures, etc.) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.).
25) What is the difference between customization and extension?
Customization is under direct user control. The user explicitly selects between certain options. Using customization a user can:
Altering the functionality of an application
Altering existing UI
Altering existing business logic
Extension is about extending the functionality of an application beyond what can be done through personalization. Using extension we can:
Add new functional flows
Extend or override existing business logic
Create New application/module
Create New page
Create New attribute
Extend/Override defaults & validations
26) What is Personalization?
Personalization enables you to declaratively tailor the UI look-and-feel, layout or visibility of page content to suit a business need or a user preference. Using Personalization we can:
• Tailor the order in which table columns are displayed.
• Tailor a query result.
• Tailor the color scheme of the UI.
• Folder Forms
• Do Forms Personalization
27) Can you extend every possible Application Module?
No..Root AM cannot be extended.
28) What is rootAM?
The application module which is associated with the top-level page region (the pageLayout region) is root application module.
29) Why can’t Root AM be extended?
The root AM is loaded first and after that the MDS Substitutions are parsed.
Hence ROOT AM gets loaded even before the time the substitutions definition from MDS layer get worked out.
Obviously, the root am cant substitute itself, hence it can’t be extended
30) What are the various profile options in OAF?
FND Diagnostics: required for ABOUT THIS PAGE and Diagnostic link on page.
Personalize Self Service Definitions: To enable Personalize page link on the page.
FND Personalization Region Link Enabled: used to enable Region Personalization links at every region.
FND Migrate to JRAD: By default set to Yes. Page would run from MDS if Yes, else it will run from AK.
FND Document root path: required for personalization migration. It is set to path of the MDS folder on the respective servers.
FND Branding image:
FND Banding Size: these profiles options are used for changing standard image (Oracle) on the page.
31) Steps for VO substitution?
1. About this Page-> VO, AM, EO, Path of Page
2. Export Commad (in cmd Prompt)
3. New .jpr =Open page
4. Look for AM and VO or EO.
5. Copy the class files of VO,AM or EO
6. Decompile into Java and store it into MyProjects (with respective directory structure)
7. Open VO.xml in a new jpr
8. Create a new BC4J based on your Original VO.
9. Create a new VO and extends original VO
10. Change the query
11. Rebuild the project
12. Go to .jpx(double click)
13. Go to Substitutions
14. Substitute Vo
15. Rebuild your Project .jpr
16. Transfer New VO class and xml to respective directory structure
17. FTP .jpx into $JAVA _TOP
18. unix command promrt CD$ JAVA_TOP
19. jpx importer command
20. Bounce Apache Server
32) What are different methods for passing paramaters?
1. Tokens
eg. vname={@AttributeName}
2. Hash Maps
eg. HashMap variablename=nre HashMap();
variablename.add(“ParameterName”,ParameterValue);
3.ThroughSession
eg. pageContext.putSessionvalue(“ParamterName”,ParameterValue)
33) setForwardURL list
There are many parameters, here is the complete list of it:-
public void setForwardURL(String functionName,
byte menuContextAction,
String menuName,
com.sun.java.util.collections.HashMap parameters,
boolean retainAM,
String addBreadCrumb,
byte messagingLevel)
Parameters:
functionName – This is the function name representing the page you want to forward to. If its null, an IllegalArgumentException will be thrown.
Also if the function is not under the current HOMEPAGE a OAException will be thrown.
menuContextAction – Determines the behavior of the MenuContext after forwarding to the new page. It accepts the following values:
OAWebBeanConstants.KEEP_MENU_CONTEXT: Keeps the menu context as is.
OAWebBeanConstants.KEEP_NO_DISPLAY_MENU_CONTEXT: Keeps the menu context as is, but will not display all menus including global buttons.
OAWebBeanConstants.KEEP_NO_DISPLAY_MENU_CONTEXT_RETAIN_GLOBAL_BUTTONS: Keeps the menu context as is, but will not display all menus excluding global buttons.
OAWebBeanConstants.REMOVE_MENU_CONTEXT: Removes the menu context
OAWebBeanConstants.GUESS_MENU_CONTEXT: Selects the given functionName function if it exists in the current menu.
If not it will try to make a guess by moving up the menu tree until it finds it. An exception will be thrown if the function could not be located.
OAWebBeanConstants.RESET_MENU_CONTEXT: Reset the menu context to the given functionName and menuName.
menuName – The name of the HOMEPAGE menu to reset the Menu context to when the menuContextAction is OAWebBeanConstants.RESET_MENU_CONTEXT.
If the menuName is not of type HOMEPAGE a OAException will be thrown. You can pass null otherwise.
parameters –
HashMap of parameter name/value pairs to append to the forward URL. The final forward URL parameters are in the following sequence:
It will first get the function’s corresponding URL call by querying the function information from the database. If the user is not authorized to execute this function, a security OAException will be thrown.
It will then append all parameters passed in the parameters HashMap. First parameter added to the HashMap will be first added to the URL. Also the framework will encode all parameter values before appending them to the URL.
It will remove all parameters if they have null values in the passed parameters HashMap. This provides an easy way for developers to set a certain parameter’s value to null if they want to remove it.
It will remove any OA Framework internal URL parameters such as bcrumb, retainAM, and so on..
retainAM – If true, all the cached application modules will be retained. If false, all the cached application modules will be released.
Developers must use this parameter to control the release behavior of the cached appplication modules.
This method will ignore any retainAM=true or retainAM=false as a URL parameter or as part of parameters
34) Code to copy rows in VO
public void copy()
{
SuppliersVOImpl pervo = getSuppliersVO1();
Row row[] = pervo.getFilteredRows(“SelectFlag”,”Y”);
for (int i=0;i35) What for isPreparedForExecution() and executeQuery() methods used?
isPreparedForExecution function will check whether all parameters are assigned properly and query is ready for execution.
On multiple navigations to the page this query will not be executed multiple times.
While executeQuery function is used for executing the VO query so that it can fetch the data from database into VO cache.
36) What is the pattern used in developing any OAF component?
MVC (Model, View, Controller)
Lists the components in the MVC architecture
Model: Application Module, View Objects, View Links, Entity Objects, Entity Associations etc.

38) If we have to initialize something during the page loading, which is the right place?
A. ProcessRequest() method of the Controller file is the right place.
39) What is the significance of ProcessFormData()?
For a ‘POST’ request the data on the page is binded to the view object in this method
40) Does ‘GET’ request result in calling ProcessFormData()?
No, only POST request calls that.
41) What is the main Controller component in OAF?
OAController is the main class and our controller will become subclass of it.
42) How does page structure get created at runtime?
OAPageBean is responsible for creating the bean hierarchy structure at runtime after calling ProcessRequest() of each of the beans in the hierarchy.
43) Where does the client BC4J objects get placed in the server?
They are located in the oracle.apps...server
44) Where does the server BC4J objects get placed in the server?
They are located in the oracle.apps...schema.server
45) Where does the Page and Controller related files get placed?
They are located in oracle.apps...webui
46) What are Validation View Objects?
They are the VVO’s used in validation of attributes, they are the BC4J components and have their AM ie VAM Validation Application Module
47) What is the version of Jdeveloper to be used in 11i or R12?
For 11i, Jdeveloper 9i will be used and for R12 Jdeveloper 10g will be used.
48) What is a Database Connectivity File?
It is a .dbc file which is specified in the project properties. The location of this file on the server is $FND_TOP/secure
49) What is a View Object?
It is a BC4J(Business Component for Java) object which encapsulates the query results. View objects will support the display of the content to user in the Page.
50) How do you create a view object?
View objects can be created in the Business components package, can be based on entity objects or an sql query. View objects based on sql query are read only view objects
51) What is an entity object?
Entity object is created based on a database table, it is responsible for insertion/updation/validation of the table data. They are stored in the oracle.apps...schema.server package directory
52) What is an Application Module(AM)?
Application module holds the related objects pertaining to an application ie. View objects, Entity Objects etc. The application module helps in getting the required database connection, maintains the page session or transaction context
53) What is the object passed to every page request?
OAPageContext object is passed to every request, using this object the controller initializes the application module object and will call the required methods.
54) Where is the view object(VO) initialization or query filtering done?
It is done with view object implementation class Ex. EmpVOImpl.java
55) What is the property to set for an AM so that the transaction state is maintained across pages?
RETENTION_LEVEL property is set to value MANAGE_STATE for an AM.
56) What is the Personalization?
Personalization means changes to the existing ‘Page’ according to the customer requirement
57) Give some examples of Page Personalization?
Addition of new columns to a table results, adding of fields, changing the order of regions, columns etc. Apart from this validation of certain fields, display of Descriptive flex fields etc can also be achieved
58) What is extension?
Extension is the changing of the existing components for adding more features or customer required features. View Objects, Controller, Application Module can be extended.
59) What is substitution?
When view objects are extended, we need to tell the applications that our extended view object should be used or substituted during runtime, substitution will serve this purpose
60) How to do register a new OA Framework page in Oracle Applications?
oracle.jrad.tools.XMLImporter utility will be used. After successfully importing the page data will be stored in metadata repository tables of the database
61) How do you move personalization from one machine to another?
Using the functional administrator responsibility the xml file can be downloaded, this file contains the required personalization done on a particular page. The same can be used to upload in a different instance. Here XMLImporter utility can be also used.
62) How is the applications security maintained during the OA Framework components development or how is the required security obtained?
The Database connectivity file ( .dbc file) has the applications username and password along with the responsibility to be used for connecting to the applications at page run time.
63) What are the different layers of onion reuse object model in OAF?
The hierarchy is as :
Controller (XXCO.java)
|__
Application Module (XXAMImpl.java, XXAM.xml)
|__
View Objects(XXVOImpl.java, XXVORowImpl.java, XXVO.xml)
|__
Entity Objects(XXEOImpl.java, XXEO.xml)
|_ Database
64) What is ‘Partial Page Rendering’ PPR?
PPR is a mechanism where in only the required part of the page is refreshed as against the whole page. The page objects fire the ‘events’ and accordingly the request is handled in the controller file
65) What are the search region options available?
Simple Search – ResultBasedSearch is the construction mode for the region
Advanced or autocustomization search – Autocustomization is the mode here
None – User has the develop the page, regions, controller etc here
66) What is the bean used for supporting transactions across pages visually to the user?
OATrainBean is used to link the pages across the transaction. AM supports the transaction context or state here across the pages.
67) How does personalization takes its effect at runtime?
After the page structure or bean hierarchy is formed with, the personalization layers get applied on top of it to come up with the final structure. Remember that is the reason why personalization is upgrade safe.
68) Name some components requiring extension?
View Objects, Controller, Application Module. Yes nested application module concept is allowed.
After you modify a class file and move it to the server what is the immediate step that will be followed?
The services of the instance ie. Apache server etc. have to be bounced so that the new code in the class file takes effect.
69) Where does the two categories of files in OAF be placed in the server?
All the xml files of the page/region will be placed in the respective TOP’s mds directory. All the class files irrespective of TOP will be placed under $JAVA_TOP which can be $COMMON_TOP/java
70) When do you create additional business components package?
Apart from B4CJ client business components package and B4CJ server business components package we create additional business components package when we develop any sharable thing such as ‘LOV’ (List of Values), ‘Poplist’ etc which will be used in multiple pages
71) How do you map the LOV created to your base page?
One of the items in the page has to be MessageLOVInput which extends the new LOV region, apart from this LOV mappings between base page and LOV region have to be created.
72) What is the default top region of any new page that you create?
PageLayout is the top level default region
73) At what level region controller for a page can be set?
It can be under a Main region under PageLayoutRegion or any region as per the business need. Provision of defining multiple controllers for a page also exist.
74) PPR follows GET or POST flow?

The data are present in JDR tables. MDS provides service to store & return page definitions. MDS collects those definitions in components/fields in a meaningful manner to build a page.
86) What is XML?
XML is a markup language for documents containing structured information.
Structured information contains both content (words, pictures, etc.) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.).
87) What is the difference between customization and extension?
Customization is under direct user control. The user explicitly selects between certain options. Using customization a user can:
Altering the functionality of an application
Altering existing UI

• Tailor the color scheme of the UI.
• Folder Forms
• Do Forms Personalization
88)Can you extend every possible Application Module?
Answer: No..Root AM cannot be extended.
89) What is rootAM?
The application module which is associated with the top-level page region (the pageLayout region) is root application module.
90) Why can’t Root AM be extended?
The root AM is loaded first and after that the MDS Substitutions are parsed.
Hence ROOT AM gets loaded even before the time the substitutions definition from MDS layer get worked out.
Obviously, the root am cant substitute itself, hence it can’t be extended
91) What is MVC Architecture?
MVC Architecture is a Model View Controller Architecture. The controller responds to user actions and directs application flow. The model encapsulates underlying data and business logic of the application. The view formats and presents data from a model to the user.
92) Which is the MVC layer VO located?
O is located in the View Layer which is responsible for presenting the data to the user.
93) Which package should include EO and AO.
The EO and AO will be present in the schema.server package.
94) What is the difference between inline lov and external lov.
Inline lov is a lov which is used only for that particular page for which it was created and cannot be used by any other page.External lov is a common lov which can be used by any page. It is a common component for any page to use it. It can be used by giving the full path of the lov in the properties section “External LOV” of the item.
95) What is a Javabean?
Ans: JavaBeans is an object-oriented programming interface that lets you build re-useable applications or program building blocks called components that can be deployed in a network on any major operating system platform.
96) What is query Bean?
QueryBean is used to execute and return the results of a query on behalf of the QueryPortlet application.
97) What is the difference between autocustomization criteria and result based search?

The data are present in JDR tables. MDS provides service to store & return page definitions. MDS collects those definitions in components/fields in a meaningful manner to build a page.
99) Why Should we give retainAM=Y?
The AM should be retained whenever you are navigating away from a page and when you know that there is a possibility to come back to the page again and data is to be retained. Example : Any navigation link that opens in a new page or any navigation which has a back button to come back to the initial page.

150) What is Validation View Object(VVO), Validation Application Module , Root Application Module , View Link , Entity Expert , Association Object , Attribute Set?
Validation View Object – A view object created exclusively for the purpose of performing light-weight SQL validation on behalf of entity objects or their experts.
Validation Application Module – An application module created exclusively for the purpose of grouping and providing transaction context to related validation view objects. Typically, a standalone entity object or the top-level entity object in a composition would have an associated validation application module.
Root Application Module – Each pageLayout region in an OA Framework application is associated with a “root” application module which groups related services and establishes the transaction context.
This transaction context can be shared by multiple pages if they all reference the same root application module, and instruct the framework to retain this application module (not return it to the pool) when navigating from page to page within the transaction task.
View Link – Establishes a master/detail relationship between two view objects
Entity Expert – A special singleton class registered with an entity object (EO) that performs operations on behalf of the EO.
Association Object – BC4J association objects implement the relationships between entity objects. For example, a purchase order header can reference a supplier, or it can own its order lines.
Attribute Set – Bundles of region or item properties that can be reused either as is or with modifications. For example, all buttons sharing the same attribute set would have the same label and Alt text.
