NPE when using POJO Data Control deployed as webcenter shared Lib

Hello everyone,
I am using Jdevelopper 11.1.1.7...
I have a methodAction Binding defined for a JSFF. I am executing this methodAction in a managed bean. When doing so I have the following exception:

This methodAction calls a Data Contol based on a POJO which is using a JAX-WS Proxy. This Data Control POJO is packaged in a separate JAR file named ServicesProxy.jar.
Both ServicesProxy.jar and the ADF application using it are deployed as two distinct shared libraries used by webcenter portal application.
An important information is that the error does not happen when debugging the ADF application on my IntegratedServer. The error happens only when deployed as a shared Lib used by webcenter portal application.
This jar file ServicesProxy is used by other applications within our portal, so I think that the data control is properly created.
Do you have any idea what could be the cause of such error?

  • Any Examples of using ActiveCollectionModelDecorator with POJO data control

    Are there any Examples of using ActiveCollectionModelDecorator with POJO data control in any of the sample packs?

    OK, here's an quick example. Create a new Windows Forms application and add a ScatterGraph and a Label to the form. Add a cursor to the ScatterGraph, then add the code below to the form. This generates 50 random data points when the form is loaded and plots them, then uses the cursor's AfterMove event to display the current X and Y positions in the label. Here's the code:
    Private Sub OnFormLoad(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Const dataLength As Integer = 50
    Dim xData(dataLength - 1) As Double
    Dim yData(dataLength - 1) As Double
    Dim rnd As Random = New Random
    For i As Integer = 0 To dataLength - 1
    xData(i) = i
    yData(i) = rnd.NextDouble() * 10
    Next
    ScatterGraph1.PlotXY(xData, yData)
    End Sub
    Private Sub OnAfterMoveXYCursor(ByVal sender As Object, ByVal e As NationalInstruments.UI.AfterMoveXYCursorEventArgs) Handles XyCursor1.AfterMove
    Label1.Text = String.Format("({0}, {1})", e.XPosition, e.YPosition)
    End Sub
    Hope this helps.

  • How to cause POJO data control to use custom base ViewObject class

    ADF 11.1.1.4
    We have a POJO data control that displays data in a table.  We can filter the table using the column filters and this performs in-memory filter.   If an exception occurs I see that it is using a ViewObject for the in-memory filtering because this shows up in the stack trace.
    oracle.jbo.server.ViewObjectImpl.rowQualifies(ViewObjectImpl.java:2811)
    It uses DCDataVO which extends ViewObjectImpl
    We have a Custom base view object defined that all our normal view objects inherit from, defined in Project Properties/BC/Base Classes
    Is there any way to make the DCDataVO also extend from  our Custom View Object that inherits from ViewObject so that we can override methods?  For example if I wanted to customize the rowQualifies method.
    In DCBeanDataControl.Java I see where it actually gets created.
    vo = DCDataVO.createViewObjectFromDef(vdef, this, getApplicationModule());

    So you have already overridden then rowQualifies() method in your custom base View Object ? Are you calling super in that ?

  • Using UCM data controls in ADF application

    Using *.6 Jdeveloper/UCM/Protal Application/UCM
    Calling all the experts in Webcenter/Spaces/UCM/ADF.
    We have a requirement to design search inteface for Documents stored in UCM for Webcenter Portal and Spaces application.
    Our approach is
    Design simple ADF application (no security/templates)
    Bounded task flows using fragments.
    Framents to use UCM data controls (provided by oracle)
    UCM data control definition is extended to use custom metadata.
    package the application.
    Added as ADF library jar to portal application
    Added as Shared Library to Spaces application.
    Question.
    Is this approach sound?
    Does UCM data controls provide all the functionality, for example if we want to read a option list for custom metadata or need custom metadata in return table?
    Can we add other methods to UCM data control provided by Oracle or should we create different one?
    Is there good documentation for such requirements. We have acces Webcenter developers guide which throws some light on UCM data controls.
    Let me know if more clarity is needed...
    Regards

    Hi.
    One of my last components was a custom "Document Explorer" and I used for first time JCR Data Control (Custom UCM Data Control provided by Oracle).
    Sharing my experience I did something similar to you:
    1) Create a ADF Bounded Task Flow and test it individually.
    2) Add generated ADF JAR Library to WebCenter Spaces shared-lib.
    3) Add your Task Flow to Resource Catalog.
    Challenges that I found using custom Data Control:
    1) When items retrieved are content/files all custom metadata can be retrieved OOTB.
    2) When retrieving folders don't provide custom metadata like files. I used RIDC with JCR Data Control to provide all the information relative to folders. If you don't need more information about folders than the name, URI and icons then is OK :).
    3) Using JCR Data Control registers in DataControls.dcx UCM Connection name used when generate JCR Data Control. After deploy your ADF JAR Library in WebCenter Spaces you'll have problems if you don't have a WebCenter Content Connection created with the same name. (Not talking about export UCM Connection with ADF JAR Library, Data Control uses a Connection name by itself :)).
    I added extra functionallity with RIDC (not extending JCR Data Control).
    I hope this help you.
    Regards.

  • Managed Beans vs. POJO Data Control for sharing data

    Hi,
    I am currently using JAX-WS proxy client and POJO Data Controls to retrieve data from web services. This data needs to be shared across users. Normally I would use application scoped managed beans for this, but since I prefer using data controls and the binding layer, would using static POJO Data Control classes achieve the same thing?

    Hi,
    Data Controls don't exist across user sessions so in your use case use a managed bean in application scope. If you want to make this available from a Data Control
    - create a POJO
    - Use EL in the POJO to access the managed bean
    - Create a DataControl from the POJO
    This way the Data Control exposes the data as an API but itself always reaches out to the managed bean as a data store/cache

  • How to use multiple data controls in a single JSF page

    Hi,
    I am using Essbase Data Control to in my project to get Essbase Cube data into ADF table/Pivot Table.
    Suppose if [Item] dimension has this hierarchy [category] -> [Segment] -> [Brand] -> - [Item]
    I need to display Category in one column and Segment in the next Column and [Brand] in the another column.
    Different types of Category, Segment and Brands should display as table data(data values).
    Using MDX query I can not print [Item] hierarchy in different columns..so I am planning to use multiple data controls.
    Could any body help me to get the solution.

    Hi,
    sounds like you want to try the Pivot table
    http://download.oracle.com/docs/cd/E21764_01/apirefs.1111/e12418/tagdoc/dvt_pivotTable.html
    I don't think that multiple Data Controls is the solution to the problem

    It seems that problem is caused by af:query or quickquery component(or underlying view object or view criteria).
    Maybe you can drop BTF as static region directly to your page and see if this will run correctly?
    YES i have try stll does not work
    So then this is not related with "npe when using popup inside adf table column"

  • Crash when using Invoke Method: Library:Deploy Library

    I'm trying to set a library of shared variables to deploy when a VI runs. When using the method to deploy a library, Labview will crash with no error log. I am able to use Library.Open to, for example, HiliteInProjectWindow, and Library.GetFileLVVsersion (8.6). But for the life of me I cannot get deploy to work. Any ideas?

    hbcnb,
    I'm not quite sure why that is happening, but I
    can give you a work around for it.  There is a property node that
    returns the mode that LabVIEW is running in (Run-Time, Development,
    Evaluation).  If you output this value to a case structure, you can
    include your deploy code in the run-time version but not in your
    development version so that it will cease to crash.  Place down the
    property node, then select  Application » Kind.  I've included a
    picture of how to wire this up. Let me know if this helps work around
    the problem a bit easier.  
    Sincerely,
    Chris G in AE

  • Is it possible to implemnt af:query using JavaBean Data Control?

    Is it possible to implemnt af:query using JavaBean Data Control?

    Fortunately for you and me, Oracle documents this stuff.

  • Date selection will not print properly when using Microsoft Date and Time Picker Control 6.0 in Excel 2010

    I have created a field input worksheet in which the user identifies start and end dates for training sessions, using the Date and Time Picker Active X Control.  It works fine on-screen, but when the worksheets are printed, the dates that were selected
    using the date picker calendar print out in an unreadable, huge font.  The large font also appears in the print preview mode.  I've tried modifying various properties in design mode, but nothing that I have tried will correct the problem. 
    Any ideas?

    The DTPicker seems to have some bugs in it when used on a worksheet. I have overcome the above by setting the size properties to the same size as a cell and the Linked cell property to the
    cell under the DTPicker. (Even setting the Linked cell had problems with an error message referring to the Check box property to be set to true so I just set it to true and inserted the linked cell and set the checkbox property back to
    false.)
    Then the VBA code below that Hides the DTPicker after a date is selected and unhides the DTPicker when the linked cell with the date is selected. The code is for 2 DTPickers so you will need to edit to suit your requirements.
    Caveat: If the DTPicker is visible then you can't hide it by selecting the same date again. If this occurs then it is a multi step operation. First select another date and the DTPicker will hide, then click on another cell then back on the cell with
    the date to unhide the DTPicker and then select the correct date.
    Hope it helps and feel free to get back to me with any questions etc.
    Private Sub DTPicker1_Change()
        Me.DTPicker1.Visible = False
    End Sub
    Private Sub DTPicker2_Change()
        Me.DTPicker2.Visible = False
    End Sub
    Private Sub Worksheet_SelectionChange(ByVal Target As Range)
        Select Case Target.Address
            Case "$E$5"     'This is the linked cell for DTPicker1

  • Clear POJO Data control cache

    Hi I am using Jdev 11.1.1.7
    I have a POJO based Data control which am using for tree structure.
    I have this tree inside a popup.
    So when cancelling or after the purpose of the popup is over.
    I want to clear the cache of the data control.
    I tried several ways to do that like having a methods in my java class where making the object  null and calling the methods on cancel.
    But nothing worked .
    How to clear the Pojo DC.

    Hi AlejandroTLanz   ,
    I tried the above method.
    I created a method in Java class which is used to make the List null used by the tree.
    And then calling finditerator.executequery.
    I could see that the list is getting null.
    But In Java sampler It still shows that Objects are present.
    I guess the Object are still in data control cache...
    I tried to clear the DC Cache by calling the DC.resetMethod.
    But nothing worked

  • Web sevice data control deploy error.

    We developed an ADF application. We deploy this application to SOA 10.1.3.3 it works correctly. After that we add this project a web sevice data control pointing a BPEL process (initiate method).
    it works from Jdev 10.1.3.3. no problem.
    But when we deploy this application to app server . deploy works ok. but when we want to connect application
    "page not displayed error" occurs. no more information.
    it seem to us a connection error occurs to BPEL process web services.
    is there anyone face this problem? How can we solve?
    We want out ADF application works even SOA application down.
    How can we make ADF and BPEL applications like loose couple (can we add try catch block to provent general failure. Where we can add?)
    Thanks.

    when u deploy manually it goes under some other url than you specified, try to test webservice under the app server console and then webservice tab. this is how u get the actual URL to request webservice u deployed manually.other solution is to redeploy manually through app server console the webservice that you've deployed through jdeveloper.

  • POJO Data Control af:table with selectOneChoice

    Hello All,
    JDeveloper 11.1.1.6/7
    I have a peculiar issue that I am trying to solve.
    I have a POJO based data control and an af:table based out of it. One of the fields (category) is to be a selectOneChoice driven by a WS Data Control. When I drag-drop the target attribute (category) as a Select One Choice and create a dynamic list based on the WS Data Control the row becomes uneditable.
    The selectOneChoice from the jspx:
              <af:column headerText="#{bindings.children.hints.category.label}"
                         id="c3">
                <af:selectOneChoice value="#{row.bindings.category.inputValue}"
                                    label="#{row.bindings.category.label}" autoSubmit="true"
                                    required="#{bindings.children.hints.category.mandatory}"
                                    shortDesc="#{bindings.children.hints.category.tooltip}"
                                    id="soc1">
                  <f:selectItems value="#{row.bindings.category.items}" id="si1"/>
                </af:selectOneChoice>
              </af:column>
    The relevant sections from the pageDef are as follows:
    <tree IterBinding="childrenIterator" id="children">
          <nodeDefinition DefName="info.bijesh.samples.ws.model.Children"
                          Name="children0">
            <AttrNames>
              <Item Value="id"/>
              <Item Value="name"/>
              <Item Value="category" Binds="category"/>
            </AttrNames>
          </nodeDefinition>
        </tree>
    <list IterBinding="childrenIterator" id="category" DTSupportsMRU="true"
              StaticList="false" ListIter="ReturnIterator">
          <AttrNames>
            <Item Value="category"/>
          </AttrNames>
          <ListAttrNames>
            <Item Value="categoryCode"/>
          </ListAttrNames>
          <ListDisplayAttrNames>
            <Item Value="categoryDisplay"/>
          </ListDisplayAttrNames>
        </list>
    If I remove the Binds attribute from the Item definition, then the row becomes active but of course the drop-down list is empty. Any ideas on what I am doing wrong. I have uploaded the sample workspaces here - http://www.bijesh.info/bijesh/ADFWS_TestCase.zip. WebServiceHost contains the LOV Web Service and the WSClient workspace contains the test page.

    Hi,
    there is a bug I filed this week on that issue. Could it be you filed the issue as a SR with support? Because this is where I got the test case from. For me the problem reproduced witha static list as well. So if you want to check if this is the same you see, please try a static list in the SOC. If this too makes the field un-editable then its the same effect. The testcase I had was 11.1.1.7 and I fixed an issue in its POJO model to run the sample (just in case you belong to the same customer). I didn't test with 11.1.1.6 as obviously the bean data control is different in 11.1.1.7 (at least it complained about a missing class when I tried in 11.1.1.6).
    If the testcase I true is not yours, please contact customer support with your test case or send it my way in a zip file renamed to "unzip"
