Creating DFF in ADF 11.1.2.4.0

Hi Experts,
There is a requirement to implement EBS Descriptive flex fields in ADF jdev version is 11.1.2.4.0
Is implementing DFF and KFF supported in ADF?
I have seen some test case and implementations but not sure whether this is supported in the current version of Jdev or not.
Below link show a test case and implementation.

  • How to create DFF and how the values will be stored in the database

    Dear All,
    I have created DFF in OA Framework.
    That is working fine.
    But i dont know how to save values of DFF.
    do i need to attach EO with the View object which is used in DFF.
    I would be thankful to you.
    Thanks,
    sheetal mittal

    Hi Gorav,
    Actually its seeded page so i cannot do anything with teh save functionality..
    I have followed the below steps:
    1) Fst i have added Flex Field in the Seeded Page . Defined all the properties , View object name etc.
    2) After that i have created new custom View Object and entity object then add that EO in the custom VO..
    3) After that i have extended AM to add new custom View Object.
    4) After that i have extended CO and written following code :
    public void processRequest(OAPageContext pageContext, OAWebBean webBean)
    super.processRequest(pageContext, webBean);
    OAApplicationModule am = pageContext.getApplicationModule(webBean);
    NegotiationCreationAM negotiationcreationam = (NegotiationCreationAM)pageContext.getApplicationModule(webBean);
    int StrAucId = negotiationcreationam.getAuctionHeaderId();
    String strAuctionId = String.valueOf(StrAucId);
    Serializable[] Params = {strAuctionId};
    am.invokeMethod("InitLoad",Params);
    public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
    super.processFormRequest(pageContext, webBean);
    NOTE: AuctionHeaderId is the primary key of the page.
    5) I ahve written the below code in AM.
    public void InitLoad(String strHeaderId)
    OAViewObject vo = (OAViewObject)getxxEarnestDffVO1();
    if (vo.getRowCount() == new Number(0).intValue())
    Row row = vo.createRow();
    vo.setWhereClause(" AUCTION_HEADER_ID = " + strHeaderId);
    vo.executeQuery();
    else
    vo.setWhereClause(" AUCTION_HEADER_ID = " + strHeaderId);
    vo.executeQuery();
    6) But when i am saving the details it gives me :
    Unable to perform transaction on the record.
    Cause: The record contains stale data. The record has been modified by another user.
    Action: Cancel the transaction and re-query the record to get the new data.
    Please help me out.

    Hi,

  • Trying to create an annoucement ADF task flow.  Failure to authenticate

    Experts-
    I have created a JSPX page and added the announcement ASF task flow. After I deploy to my WLS instance I recieve the following error when browing the page. "failure to authenticate the user weblogic, due to: Unable to connect to discussion server."
    The java server log file throws this exception "Caused by: org.apache.ws.security.components.crypto.CredentialException: Failed to load credentials. Inner Exception: [Keystore was tampered with, or password was incorrect]"
    I am able to login to the OOTB discussion web app using the same user but not my custom ADF JSPX page.
    I have configured the JDEV Discussion forum connection with the following properties..
    keystore.location = "E:\Oracle\Middleware\user_projects\domains\working_domain\config\fmwconfig\webcenter.jks"
    keystore.type=jks
    encryption.key.alias=orakey
    encryption.key.password=welcome1
    keystore.password=welcome1
    I can test this connection with success.
    Anyone know why I can correctly login the OOTB discussion app using my default weblogic user but not the custom ADK app?
    I am also using the simple login page jdeveloper creates via the "configure ADF security"
    Thanks-

    even I am getting the same problem. I created a Discussion Forum Connection from my Jdeveloper. I tested the connection to be successfull.
    and when I run the ADF application having webCenter Discussion forum taskflow as a region , it says

  • Can't create a true ADF Libray JAR FIle

    I created a Model project. Then created an ADF Library JAR File Deployment Project to deploy the jar to the file system.
    I then, created a separate project and tried to add the export jar file to it via a File System connection in the Resource Palette.
    But, when I right click on the jar file in the Resource Palette, I only see 2 options, "Open" and "Advanced Search".
    I expected to have an option to add the jar to the selected project.
    Now, I am able to add the jar to the Project if I go to the projects properites, then add the jar via the "Libraries and Classpath".
    Note that even the icon for the jar is different than those from other System Jar files (the bookshelf/library icon).
    The icon I see for my jar is hard to identify, sort of like a torch.
    So, what is going on?
    I have double and triple checked that my deployment profile is for an "ADF Library JAR File".
    I have deleted the default deployment profile and create a brand new one.
    Still, the same issue.
    Any ideas?
    Thanks in advance.

    When you say you see the XML files for the EOs & VOs do you mean in the resource palette? Never mind, let's take a step back.
    Via the following link this is what you should see for a Model project ADF Library JAR that contains EO/VOs etc:
    https://dl.dropboxusercontent.com/u/12154176/pic01.png
    If you were to right click on the JAR this is what options you should see:
    https://dl.dropboxusercontent.com/u/12154176/pic02.png
    I'd suggest you're still doing something wrong when you create the ADF Library JAR. To assist you via this link:
    https://dl.dropboxusercontent.com/u/12154176/Model.zip
    ...you'll find a previous workspace/project I've setup. If you right click on the Model project look to the Deployment options you'll see an ADF Library deployment profile called "Model_Model_adflib". If you exit out of the preferences, right click Deploy -> select Model_Model_adflib, the appropriate ADF Lib JAR will be created under Model/Model/deploy. Returning to JDev and the Resource Palette, add a file system connection to this deploy directory, then you should see what I see above.
    Let us know how you go.

  • Creating a New ADF Page Template

    -- I posted this in the WebCenter forum but since it is primarily around ADF I thought I would post here also
    -- Extending WebCenter Spaces 11.1.1.3: Creating New Page Template w/Float Div
    Hi all,
    I am attempting to create a new group space page template for Spaces that has a floating div on the right side that will have content wrap around it. It should look similar in concept to the image in this link:
    http://css.maxdesign.com.au/floatutorial/tutorial0104.htm
    This seems like it should be simple enough but I need to allow dynamic content to be added each region with Oracle Composer. Currently when I am testing this and add content the two regions end up in distinct columns. This appears to be a result of the html elements that get wrapped around the content by the ADF tags. Has anyone successfully created a page template / page similar to this or have any ideas on how I might get it to work? Below is the current code I am using:

    Hi ,
    I understand that you want to be able to select content type when creating a wiki page to a Wiki Page library. In browser ,you cannot add content types to a wiki page library .You need to edit the library in SharePoint Designer.
    Open the site in SharePoint Designer.
    Click on the library. Check ‘Allow management of content types’ in the Settings section.
    Then you can add content types to this page library.
    Then you can add content types in the Site Content Types gallery which inherit from the Wiki Content type.
    Add the newly added content type to the Wiki Page Library.
    In this way ,when you add a new page in the Wiki Page library ,you can choose a different content type .
    Edit the content type in Library Settings .Choose Advanced Settings for the content type .Here you can upload new page for the content type .

  • Jdeveloper remove some Jar files while create deployable of ADF Application

    Hi,
    i am using JDeveloper11.1.1.5 with weblogic server 10.3.5
    i have created one ADF application.
    it works fine with integrated server.
    now i want to create the Deployable EAR file for this application to deploy it on another server (Other Than IntegratedWeblogic Server)
    when i try to create the EAR following trace would be printed on Deployment-Log

    if you see the lines highlighted by @
    here it removes the trinidad-api.jar and trinidad-impl.jar from my EAR saying that "Removing the following prohibited entry from the EAR: lib/trinidad-api.jar "
    so why this happen ?
    this EAR file creates problem while deployment.
    if i manually put both Jars in EAR, it works fine..
    can anybody please help on this ?
    thanks in advance...

    hi timo,
    thanks for quick reply..
    but i don't think so it is present on weblogic because i not put that files in EAR it gives me some classDefNotFound or classNotFound exception.
    and when i put those files, my application is deployed and workes fine..
    thanks,

  • How to Create LOVs in ADF  pragmatically  if DataControl is from WebService

    Hi All,
    I consumed Web-services in ADF application to do CRUD operation on some tables(for example i created one web service which perform all crud operations on database that tables are mapped)
    now what i required is i consumed that web services, I created DC from that WS ,And In ADF application i created insert operation the data is inserting well,but that tables are mapped i want to
    display LOVs for that foreign-keys as we know id we created ADF application from database we ll able to create LOVs like thatbut this is possible to create only through pragmatically.
    is there any links for creating LOVs from Web-services Data Control.
    Thanks

  • How to create Services in ADF

    Hi ,
    I have requirement to create independent services in ADF , which when called, independently complete the tasks of putting or fetching data from the Database., irrespective of the page defs from where it is called.
    For example a Look up service,
    It should take the Identifier to be looked up and return the arraylist list of values matching the indetifier.
    When I am using this service on a button on my pages, I do not want to bind the page with the iterators(view objects)/ service methods bindings. It should be independent.Possibly a std POJO object instantiation.
    I want to isolate the Page from the underlying services implementations used, the primary reason for doing this is that the implementation have to change dynamically including the datasources with which thy interact.

  • Database Constraint Error Handling on create/edit (Struts ADF)

    Hi,
    In our project we use Struts ADF (JDeveloper 10.1.3) technology. And we're facing the following trouble with it.
    If we try to create a record that violates say Unique constraint in the database, then during commit procedure of the AppModule's Transaction an exception occurs.
    We handle this exception with our extension of DCErrorHandlerImpl. And we have to do the rollback action because the Transaction became invalid and we cannot do the commit since there was an error.
    But unfortunately appModule.getTransaction().rollback(); forces ViewObj to loose all of the newly created rows. Because of this, after pressing submit with the same (violating) data once more our edit form shows the first row in a rowset.
    Are there any ideas about what we may be doing wrong?
    Any standard approaches on database constraint error handling?
    The "before/after commit/rollback" approach is very effort-consuming because we have a lot of views in our app and tracking all of them may become a nightmare in future.
    Thanks in advance.

    Larry

  • How to create stopwatch using adf?

    Hi experts,
    do you guys have stopwatch application sample using adf code?
    i try to create using javascript in adf but there is a problem with refreshing the value.
    Thanks
    Hadi Wijaya

    actualy i want to capture total time spent by user, the scenario is like this:
    1. user click start button to start time.
    2. then time running and will shown in adf input text using this format hh:mm:ss
    3. user click stop button, then total time will insert into database; total time = stop time - start time
    more or less it will looks like timer in the chess game.
    im using Jdeveloper 11g version 11.1.1.0.2
    i try using javascript ... using setTimeout but it still not working
    Regrards,
    Hadi Wijaya

  • Create DFF using OA Framework

    Hi,
    I have a requirement where i have to create a DFF usng OA Framework. When i checked the Developer's Guide they have mentioned that first we have to create the DFF in APPS and then use the same in OA Page using Flex item.
    My question is without creating the DFF in the Apps can we create the DFF dynamically using java code.
    Kindly help.

    Hi Reetesh,
    I have used the code what u have shared in the processRequest of the CO.
    Below are the details which i am using in the Page.
    I have created the DFF in 'Application Object Library' application so only i am using the Application Short Name as "FND" along with this i am giving the Name as 'FND_COMMON_LOOKUPS' , Type as descriptive and segment name as the name of the segment what i have mentioned.
    But stil i am getting the Null Pointer Exception.
    Below is the stack details:

  • DBSequence usage creating 2 rows (ADF BC)

    As a "newbie" with JDeveloper (10.1.3) development, I have approached my project development referencing the Oracle ADF Tutorial for Forms/4GL Developers using the same technology specified in the Tutorial (ADF Faces Components, ADF Faces HTML, JSF Core, JSF HTML).
    This is a small project (a team knowledge base) that actually fit well with the Tutorial (SRDemo) example.
    The problem I am encountering is 2 rows are created when using the same approach in the Tutorial with a "Create" and a "Confirm" page. The first row has the correct data entered and the second row is blank with the next sequential ID. Row ID is of type DBSequence and a database sequence is used and populated with a BEFORE INSERT TRIGGER.
    So when I've created 2 new rows, the results appears as follows:
    5 8/2/2006 SW Prototype Dev JD 10.1.3 WN 111111
    6
    7 8/2/2006 SW Database DB 10g WN 111111
