Business Component and Task flow learning

Hi everyone,
can anyone suggest me how and from where I need to start learning Oracle BC ,Entity objects,View object and task flows concept . I am familier with Oracle ADF but never used this components.
so Please help me to learn the thing quickly.
Thanks in advance

Hi,
have a look here ADF Insider Basics - Introduction to Oracle ADF Business Components
Note that the Fusion Developer Guide product documentation is all about ADF BC

What is the diffrence between business Activity and task?

Hi plz explain business activity and task

Hi Venkat Mallela,
Sorry to say this, but you must stop rewarding your own threads. A user registered today (10/25//2007) and posted many threads and always rewarded you as thread completed. I dodn't think it is a coincidence.
If every SDN member starts playing this dirty trick, then there is no meaning to use SDN. SDN is for the people who share their good project experiences by helping other members by answering the issue.
As I mentioned before, I should take up this issue with SAP officials if this happens again.
Not only you, some other members were also recently started practicing the same trick, which is not a good thing.
Hope you understood the voice of other forum members like me.
Thanks,

PI 7.1 ,Business component and business system.

Hi Everybody,
Can you please tell me when should we use a business component and when to use a business system
thanks a lot,
Ramya Shenoy

Hi Ramya,
A common question :)..if you search sdn you will know more about this
Business system : Use when you know the end system (like system name, ip etc). Generally ECC, R3, JDBC systems wtc..
Business service : When you know that it is a file or htto system but dont have their details.. Generally Soap, HTTP, File etc...

Business Component and Communication Component

hi
is there any difference between Business Component and Communication Component in PI 7.1.
I assume business service of pi 7.0 is become Business Component.

Business Service of PI7.0 is now Business Component of PI7.1 with the same functionality
Communication Component is containing Business Components, Integration Process, Business System)

Problem with ADF security and task flow calls

Hi.
I am using JDeveloper 11.1.2.0.0.
I encountered a problem when tried to apply ADF security to my application.
The way to reproduce the problem:
1. Create new Fusion Web Application;
2. Import Business Components from Tables from any existing schema and add at least one table to the ApplicationModule.
3. Create "welcome page" (for instance, welcome.jsf). Add a button with fixed action outcome "test".
4. Create test page, for instance, test.jsf. Drag and drop any view object from Data Controls onto the page and create a form with navigation controls. Add a button with fixed action outcome "return".
5. Create bounded task flow, name it "test", drag and drop our test page on it - the page will be the default activity. Add a task flow return activity. Add a control flow case from the default view activity to the return activity, set From Outcome property to "return". So our return button should cause the task flow to exit.
6. Open adfc-config.xml in diagram mode and place our welcome page on it. Then drag and drop the test task flow to create a task flow call activity. Add a control flow case from welcome page to task flow call activity, set the From Outcome property to "test". So our test button should call the test task flow.
7. Configure application to run the unbounded task flow starting with Welcome view activity.
At this point all works as expected: when application runs, the welcome page is displayed with test button. Pressing the test button results in displaying the test page, return button leads back to the welcome page.
Now let's configure ADF Security.
Run the ADF Security configuration wizard, choose ADF Authentication and Authorization.
On the second page select Form-Based Authentication, check the Generate Default Pages flag.
On the third page choose No Automatic Grants.
On the next page keep the Redirect Upon Successful Authentication unchecked. Press Finish.
Open jazn-data.xml to configure roles, users and resource grants:
1. Create application role test-role.
2. Grant the test-role privileges to view the test task flow.
3. Create user and grant him the test-role.
Now we have the public available welcome page and the test page with restricted access.
When application runs, the welcome page is displayed as expected. Pressing the test button redirect us to auto-generated login page. After successful authorization the test page is displayed. But nothing happens if we click now the return button for the first time. When we click the return button once more, the application crushes with Error-500 and message "Target Unreachable, identifier 'bindings' resolved to null". The exact error trace depends on UI control bindings, but looks like this:
javax.el.PropertyNotFoundException: //C:/Users/DUDKIN/AppData/Roaming/JDeveloper/system11.1.2.0.38.60.17/o.j2ee/drs/Test1/ViewControllerWebApp.war/test.jsf @10,120 value="#{bindings.Id.inputValue}": Target Unreachable, identifier 'bindings' resolved to null

Any suggestions?

@Lovin_JV_941794
The welcome page is public available since it does not have appropriate PageDef file.
Login page comes not from the welcome page, it comes after attempt to access the test page. So after the login succeeded the test page appears, because redirect to welcome page after successful login is not configured. I do not need to return the welcome page at this moment, I need to go to the test page.
It seems the task flow call stack to be destroyed after redirect to login page.

App module view object row currency and task flows

Hello -
Using JDev 11gR1. My application uses ADF Rich Faces with ADFBC.
I have case where I want to
a. select a row in a table based on a view object
b. hit a button to invoke a method in an application module.
c. in the app mod method, call getMyViewObject().getCurrentRow() to get the row selected by the user
d. "do something" with the row
In 10.1.3, this worked fine.
In 11gR1, I am having problems:
1. The above situation works fine if I have a regular page.
HOWEVER,
2. The above situation does NOT work if my table is in a page fragment in a task flow. (The getCurrentRow() returns NULL.)
For case #2 I've checked the following:
* verified that the selectedRowKeys and selectionListener attributes were set on the table in the page
* verified that I'm using the correct app module instance (I have nested application modules).
* experimented w/various transaction and data control scope settings in the task flow definition.
So... from those details is there something obvious I am doing wrong? It looks like cases #1 and #2 above use different row set iterators. Is there a way to grab the correct row set from within my app module method? Does this have something to do with the data control scope defined by the task flow? (For 11g do I need to "rethink" sticking logic in the app module and instead placing it within a managed bean get access to my ADFBC objects via the bindings layer?)
Thank you for reading my question,
-- Scott

See this article for View Object tuning tips:
http://www.oracle.com/technology/products/jdev/tips/muench/voperftips/index.html
Are you planning to use this AM as a nested AM inside other application modules?
If you don't the "selection AM" will have its own, separate database connection/transaction.
If you do, it will share connection, transaction with its containing "root" AM.
It may not be relevant to your application, but just realize (which is explained in the article I point to above) that view objects that are not related to entity objects do not "see" pending changes in the current transaction. That feature depends on the VO/EO cooperation. It's fine to build VO's without an EO -- in fact we've made it easier to do this in 10.1.2 in the Design Time wizards -- but you just want to make sure you realize what features it's giving up. If you don't need those EO-related features, then by all means create an Expert Mode VO that's not related to EO's.

ADF Regions and Task Flows

Hi,
I'm attempting to create a search bar, that would be added to all of my pages in my application.
I have created a fragment that has a comboBox, a text field, and a commandButton. These three things make up my search bar. Then I added the fragment to its own bounded task flow. I then added the task flow to one of my jspx's as a region.
Ideally, I'd like to do that on every page.
When the search commandButton is pressed on any page, I would like the user to be redirected to a 'search results' page (that is not a fragment). With the value selected in the choice list, and the value entered in the input Text, I would like to call an executeWithParams before entering the 'searchResults' page.
I'm wondering how I would do this with task flows, considering I have my searchBar in a boundedTaskFlow, and my other pages are not. There is no 'call' to my Search Bar bounded task flow, it is just a region on all the pages.
What can I do to navigate from my search Bar (in a region on all pages) to my search result page?
Any help or guidance will be appreciated.
Thanks,
Joel

That's a good point.
I oversimplified my original explanation. I don't need the search bar in all pages, but many pages.
I went back and forth between A) making multiple templates, or B) creating a facet for the search bar in my current template, where pages that use it can place the search bar fragment/bounded task flow.
I was trying to go with option B.
Which option is easiest/best?
Thanks,
Joel

Business Roles and Tasks

Hi experts,
We´re involved in a SAP CRM implementation. We´d need to know if it´s possible to link Transaction Types with a Business Role. This is, when the user goes to create a new task, a window pops up with all tasks: is it possible to limit Tasks by Business Role? Maybe there´s a customizing point where you can define, by business role, the availabe tasks for that business role.
Thanks in advance.
Javier

Hi Javier,
As far as I understand you want to restrict transaction types per business role.
You can achieve this by customizing. You can create a transaction profile in customizing for each business role and assign the transaction types you have created to this transaction profile.You can find this customizing activity in spro transaction.
Then you can assign transaction profile you have created to your business roile by assigning function profile 'transaction profile' to the business role in crmc_ui_profile tcode.
In this way when you login with the business role the transactions you have maintained in transaction profile will only be shown up in the pop up.
I hope this helps yiour requirement. Let me know if you require any further information. Thanks.

What is relation of Business component and EJB3?

Hi
Thank you for reading my post
I saw that we can use Business components to make data driven pages very easily
can some one explain me , what is relation of Business components and EJBs ?
Does business components use EJB 3 ?
What about toplink , Does Jdeveloper provide better tooling for toplink persistance or EJB 3 persistance ?
Thanks

ADF Business Components is a Java framework we developed at Oracle to make development easier.
ADF BC doesn't use EJB 3.0 - and on a certain level it is an alternative approach to EJBs.
To see what ADF Business Components offers you out of the box to make you more productive read chapter 4 of the ADF Developer Guide -
http://download.oracle.com/docs/html/B25947_01/bcintro.htm#sm0051
The bottom line is that when you use ADF Business Components you end up writing less code.
With ADF you can use either ADF BC, EJB, or TopLink to build your application.
In terms of mapping capabilities - we currently offer richer and more visual mapping support for TopLink then for EJB 3.0.
Note that when you use EJB 3.0 and you deploy it to Oracle AS you are actually using TopLink as the JPA implementation.

Business Object and tasks for Plant Maintenance

Hi,
I would like to know which object and method should I use to create the following tasks?
Inspect equipment to check if faulty
Replace equipmentCreate purchase order
Maintain equipmentCreate service order
Thank you.

Hi Arun,
Swtich on the event trace using tcode SWELS and then perform each of the operations you mentioned above. Then see the event trace using tcode SWEL to check which business object events and business objects are associated with these operations i.e. inspect equipment, replace equipment, maintain equipment etc.
Then you can drill down in those business objects using SWO1 tcode and check if there are any methods for your requirements or not.

BPM Process and Task Flow association

Hi,
I deployed one BPM process on a partition called "common". It has a human task, so when I am deploying the human task as separate adf ui project, do I need to specify the partition in hwtaskflow.xml as
hwTaskFlows
xmlns="http://xmlns.oracle.com/bpel/workflow/hwTaskFlowProperties">
<ApplicationName>worklist</ApplicationName>
<LookupType>LOCAL</LookupType>
<TaskFlowDeploy>false</TaskFlowDeploy>
<PartitionName>common</PartitionName>
Or is it ok, to deploy without mentioning the partition.I am deploying both the bpm and adf ui projects using ANT scripts.
Regards,
Subhashini

Hi Subhashini
No. There is no need to mention partition name in this file. Infact its better if you do not mention. In this way, you can deploy the taskforms to any partition in any environment.
Thanks

when I compile time sheet, I want to fill field task type, task component, task level, sender purchase porder, PO item e service number but the system give me an error, LR105, "service does not exist". I uderstand that this error is caused from missing record inderivationor task component but I work on more services.
Is there anyway to set in this derivation all the services or a range of services?

ADF task-flow and transactions

Hi All,
I have created a web application using ADF and JDeveloper 11.1.1.4. The ADF web application has two pages 'Search' and 'Edit'. The 'Search' and 'Edit' are page fragments. I have two bounded task flows 'search-flow.xml and 'edit-flow.xml'. The search and edit functionality has been created as dynamic regions by dragging the task-flows onto the JSF page.
The bounded search-flow.xml has page flow from search ----> edit(Parent Action component)
The bounded edit-flow.xml has page flow as *-->edit----> search(Parent Action component)
User comes from login page to the search page. On search page users can choose to search for records and edit individual searched records or create a new record using 'CreateInsert' button. Either way users end up on the edit page.
On the edit page, users see a form to fill or modify. They have the choice to navigate back to search page using 'Search' button or commit changed record using 'Save' button or create new record using 'Create' button
The application is functioning 90% as expected, only problem is the transaction management part if the user does not care to save each time the edit is made.
Say for instance, on search page user press ' CreateInsert' button which takes the user to edit page and then without saving the new record user presses 'Search' button which takes the user to search page and so repeated goes back and forth cycle.
In such cases the transaction never ends, The primary key for each new record is retrieved from the DB sequence only on persisting to database. A place holder like negative integer is used for the primary key temporarily till new record is persisted to database.
As per best practices, I am using the checkUncommittedDatabehavior which prompts the user when navigation is done away from the edit page i.e. without saving on pressing the 'Search' button on edit page. User can choose 'OK' or 'Cancel' which comes bundled with the ADF checkUncommittedDatabehavior property. Even after selecting OK the new record does not seems to be rollbacked (Issue 1).
eg:, if the user performs the cycle(i.e navigating between search and edit pages without commit/save) 'n' times, new entity records are created with primary keys -1, -2, -3, -4 ........ so forth. As I said earlier a proper sequence number for the primary key is assigned only if a record is persisted to the database.
Now on the 'n+1' cycle the user fills the records and clicks commit, it comes up with a error 'primary keys with nulls from previous uncommitted record (i.e; 1,2,3, .....n) creation.
I guess the transaction management is not happening correctly and not completing during these cycles (1, 2...n) Note: I am not using 'Task Return' components in my bounded ADF task flows, just commit operation 'Save' button in edit page and checkUncommittedDatabehavior.
Also, in search-flow.xml I have following configured under 'Behavior' tab Transaction ---> No Controller transaction and ' Share data controls with calling task flow checked
in edit-flow.xml, these configurations are in place under 'Behavior' tab Transaction ---> Always begin new transaction and ' Share data controls with calling task flow checked and Critical checked and 'task flow rentry' as reentry-outcome dependant.
Thanks

Hi Frank,
I checked the DB sequence is setup correctly. I have also modified the problem description above for better understanding.
2. When users press OK, navigate to a commit method activity (just drag and drop the commit operation).
-- When user presses OK, I need to rollback instead of commit to make users lose the unsaved work and controller should navigate to the search page. Here, the message panel with Cancel and OK is shown automatically with the <af:checkUncommittedDataBehavior/> property, I thought the framework will do the rollback for me. If I need to do rollback manually, how to do it, because I cannot see the JSF related source code for the <af:checkUncommittedDataBehavior/> dialog box. Please suggest what to do
3. If they press cancel, have the return activity rolling back to the save point taken when the user entered the bounded task flow (edit task flow)
-- If they press cancel, user stays on the same page, so I will leave future action to the user. This bit is working fine in my app.
Thanks

Problem reentering task flow in dynamic region

Hi All,
I have problem with reentering task flow in dynamic region.
JDeveloper/ADF 11.1.2.3.0
Use Case:
Application contains bussines modules(implemented as bounded task flows) displayed in dynamic region.
In some modules, default activity is Method Call activity which performs some validations(input parameters, state of records in db, etc.)
and if some conditions are not satisfied, shows message to the user and exits module (navigates to Task Flow Return activity).
Problem:
If user tries to start the same module again, nothing happens(message is not shown).
If user choose some other module and after that start first module, message is shown(so I suppose this means that task flow was correctly exited first time but dynamic region state was not refreshed).
Current implementation info:
Dynamic region has attached regionNavigationListener which resets taskFlowId variable in dynamic region bean if regionNavigationEvent.getNewViewId() == null but this listener is not called if Method Call activity directly navigates to Task Flow Return activity.
(if user navigates to Task Flow Return activity from button on some page, this works as expected)
Also, I tried to reset taskFlowId variable from task flow finalizer and to programatically refresh region binding, but this still doesn't work.
So, am I missing some point about refreshing dynamic region or this is bug in ADF?
Thanks,
Dario

I don't have any popup.
There is only page which contains dynamic region.
This dynamic region can be empty or can contain one of business modules(bounded task flows) which are invoked from menu.
In some cases business module must exit(by invoking task flow return activity) immediately after invocation(because some business validations fail).
In this case, module will show message to the user.
Problem is that if user call the same module again, nothing happens(message is not shown) because regionNavigationListener(which only purpose is to reset taskFlowId variable when business module exits) is not triggered when Method Call activity(which is default activity in BTF) navigates to Task Flow Return activity.
Also, I tried to use Router activity instead Method Call, but problem still exists(regionNavigationListener is not triggered).
Obviously, regionNavigationListener is called only if navigating from page(or fragment) and this is probably a bug in ADF so I opened SR.

How to invoke different pages/bounded task flows from Radio Group faces control ?

Hi,
I am quite new to JDeveloper and Java. Trying to call three different pages/bounded taskflows depending upon the each selection of radio buttons in Radio Group of 3 Radio buttons.
Advance appreciation for hints/guide line for doing the same.

Hi,
I can't code it for you, but the way it works is that you create navigation cases to the pages and task flows. Then you set autosubmit=true for the radio group component and define a value change listener. The value change listener then would do the navigation following the navigation case names determined by the radio settings.
To implement this I suggest to
1. create a hidden command button with its action property pointing to the same managed bean handling the value change event (just double click the button to create the managed bean method)
2. In the value change listener, change the navigation case returned by the action method
3. In the value change listener you call
ActionEvent ae = new ActionEvent( (RichCommandButton)valueChangeEvent.getUIComponent().findComponent("button_id"));
ae.queue()
