Is it possible to base a data control on an interface? JDev 10.1.3.4.0.

Hi, I've created a Spring based POJO service which consists of an interface and it's implementation - e.g. TrialService and TrialServiceImpl. I created a data control from TrialServiceImpl.java - so far so good. In the DataControls.dcx, I amended FactoryClass for the TrialServiceImplDataControl to point to a class that uses Spring to get the bean containing the method I want to execute rather than using the Oracle factory.
This all works fine - I can drag an accessor attribute like 'getTrials' from TrialServiceImplDataControl on the data control palette onto a JSF page as a table and it populates it with the List returned from the method getTrials on TrailServiceImpl.
I'd like to be able to amend the data control definition of the service to be based on the interface rather than the implementation. Is this possible? I've tried changing the TrialServiceImpl.xml and DataControls.dcx files to change the bean definition and bean class settings to TrialService rather than TrialServiceImpl but it doesn't seem to recognise it.
It would allow more flexibility if the data control could be based on an interface (I know it can only be created from a concrete class). I may want to change the bean definition in future and have another concrete implementation of the TrialService interface by amending my Spring config xml file but as it stands I'd also have to manually amend the data contol to pick this up or create a second data control.
Thanks for any info you can shed on this.
Paul.

Hi, solved this myself. The data control can be amended to point to the interface. My problem was I left the following tag in the TrialService.xml file as a comment:
This causes the contents of the data control to appear empty in the palette. With this removed, the contents reappear and pages work as before.
Tks,
Paul.

Exception while creating Data Control

Good day house,
I have been doing some research on using business components design in other IDEs with Oracle ADF faces within JDeveloper 11g.
I went through the following steps
create a Java EE web application - a model and viewcontroller project
imported my EJB project jar file - but I could not get an icon to show me the beans within my jar, so I imported the source instead
On importing the source, I right click on my bean classes and chose create Data control but it comes with an exception

2. Why the exception? Is it a problem with my JDeveloper installation?
3. Is it also possible to create a data control from any plain java object/interface.
thanks in advance

Did you create the weblogic domain with the Oracle Webcenter Spaces option selected? This should install the relevant libraries into the domain that you will need to deploy your application. My experience is based off WC 11.1.1.0. If you haven't, you can extend your domain by re-running the Domain Config Wizard again (WLS_HOME/common/bin/config.sh)

Calling Data Control from Session bean

Is it possible to use workshop data control from with in Session bean.

If the client code is located in the same "deployment unit" (e.g. EAR
file) as the EJBs, then you can pass the data by reference.
Serialization is required when crossing between deployment units. This
is required to support redeployment.

I recently downloaded WL6.0 and I noticed that when a
session bean returns data to its client, the data is

Does the serialization occur because WL6.0 put session

because of the way WL6.0 compiles the RMI stubs? Thanks

Web Service Data Control Refresh

Hi,
We are creating the data controls for one of our web services and using the data control to create the user interfaces. Now the web service signature is changed and we would like to refresh the data control definition. But I am unable to find about regenerating the data control.
If we use web service proxy, there is an option for regenerate the proxy. Can you please help in refreshing the data control based on the changes in the web service definitions.
Thanks,
S R Prasad

simple! Refresh data control may now work. Remove the corresponding defs from connections.xml & datacontrols.dcx (AdapterDataControl). Refresh data control panel. Close jdev & open again. Generate the web services again. Make sure in both files the name attribute matches. You might have to re-commit all the files again (mostly just replace). You're all set.

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 ?
Cheers

Hi again,
Several points that can help more:
1. If you are working with Dot.Net, then I highly recommend read the first link that you got! This is nice and simple coding. Another option is this link which is even better in my opinion:
http://www.dotnetgallery.com/kb/resource21-How-to-store-and-retrieve-images-from-SQL-server-database-using-aspnet.aspx
2. As i mention above both link use the column's type image. There are several other option of working with Files. In most of my applications architecture I find that it is better to use a column which let us use any type of file and not an image column.
In choosing the right column's type for your needs basically your fist question should be if if you want to store your data inside relational database environment or outside relational environment. It is a good idea to look for blogs on this issue. Next
if you chose to store your data inside then you need to chose the right column type according to your server version. I highly recommend to look for blogs on the differences between those column's types: IMAGE,

URGENT ! Is it possible to create a xml data control description file

We are encountering serious problem when generating data control against java bean build from java classes generated with xml top link mapping.
As workaround we have created a new xml schema that generate the java classes in a way data control may be generated correctly but we have to declare manually each class for java.util.list attribute that are not types by top link.
Unfortunately some classes seem not to described by a data control xml files for a reason we cannot understand because others similar classes are correctly described.
To gain time - we have to finish our development -we would force de data control structure by manually adding class data control definition file that are missing.
Just adding the file in the pasckage is not sufficient.
What do we have to update to make this file active ?

Solved my problem by referencing the parent class correctly so the child class xml definition was created by the data control wizard and editable in the structure window.

Is it possible to create data control from wsdl when complextype is used

Getting DCA-40015 error when trying to create a data control from WSDL file.
The error clearly says complextype is not supported . just trying to see if there are any workarounds . because creating data control will save time in developing user interface by dragging and dropping the the data control in jsf page. jdeveloper webservice tester is able to create user interface for me based on wsdl when i run it , trying to develop the user interface using jsf pages
oracle.adf.model.adapter.AdapterException: DCA-40015: Failed to create the structure for schema element "result". The complex type definition of the element is not supported.

Hi,
I could reproduce what I did:
- created WebService from custom Pojo Model
- Made sure all entities implemented serializable
- In the WebServices Wizard, I created XML representations for my entities
- tested with OC4J WebServices tester
- Built ADF data control from WSDL file of deployed WebService
- Created dependency t project containing the POJO entities
- Selected result.xml of each method exposed in the WebService project
- In the structure window, selected "item" (result-->item)
- changed Bean class to my entity class name (absolute name)
This showed my entity in the DC palette

Clear all rows in a Bean Data Control

I am using JDeveloper 11.1.1.6
In my use case I have a screen that interacts with a Bean Data Control I have followed the steps in the following URL to create a Bean Data Control
http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_36/jdtut_11r2_36.html
My screen successfully interacts with the Bean Data Control. This screen lives in a Bounded Task Flow (BTF). I can add rows using a Create Insert binding and can delete Rows as well. Once the user gets all rows into the Bean Data Control that they want inserted to a DB table, I can iterate through the Bean Data Control and post those records to the DB. It is possible for the users to add rows to the Bean Data Control and then link to a brand new screen which is in a different BTF which leaves rows in the Bean Data Control. Now the user goes back to the original screen. Upon returning, I want to empty (clear all rows) for the Bean Data Control so that they have a fresh start. Could you please provide guidance on what I might need to do to be able to clear a Bean Data Control when entering a BTF

Hi,
You can create a method to clear your Bean Data Control and call it with an invokeAction with property refresh="ifNeeded" and refreshCondition="#{pageFlowScope.isTimeToClearAll}", so pageFlowScope.isTimeToClearAll must be true only when you need to clear the BDC.

Refresh the object associated with a Row in a Data Control?

I am using EclipseLink & have an issue with multiple updates of the same Row. During an update, a new instance of the entity is returned by the update method. The instance bound to the Row is not updated with this new version and subsequent updates fail with an optimistic locking exception since the entityVersion hasn't been updated.
Question: Is it possible to refresh the instance associated with a data control Row? I can remove rows, create rows, but it is not apparent to me how to update a row. I am trying to avoid doing a full retrieve on the bound iterator.

Hi!
The issue here is, by my opinion, a gap between ADFm and EJB 3.0 in use-cases with large data sets. If you search this forum, you may find related thread by Pedja about problem of feasible "scrollable" af:table with large number of entities in EJB finder result list. Unfortunately, the ADFm "paged" fetching is in mismatch with EJB support for "paged" (or scrollable) results lists. The all results of EJB finder method are retrieved from data source, stored in memory (thus breaking the heap) and transferred to ADF datacontrol. Then, and only then, ADFm paged fetching and caching mechanisms are employed – but they are just cosmetics as the main data set is permanently stored in memory as List<?>. The workaround is, as Pedja discovered, to write completely proprietary TableCollectionModel which completely evades ADFm and is implemented by set of EJB Session methods for paged acces to datasource through TopLink and native database queries (enabling retrieval of particular range of rows instead a complete result set). Of course, this is very complex coding experience and I find it a not acceptable for efficient development of modern applications on ADF + EJB stack, especially as it brakes a technology independence promoted by EJB and EclipseLink and other standards-based technologies (as you have to use database-specific native query implementation for paged /scrollable access!).
What I want to say is that I have feeling that ADF support for EJB is not complete in full extend and that ADFm is still much better suited for BCs then for EJBs. I hope that this will be solved in future as this issue may pose a significant issue on application development in enterprise-level area where it is supposed that we are dealing with BROWSING also a large data sets.
Yes, I emphasize a BROWSING as I strongly oppose a dogmatic approach that SEARCHING is a solution for every use-case. From theory of information, the system SHOULD NOT limit the user in accessing ALL information (based on access rights, of course). So the idea that SEARCH forms should be used to bridge a architectural gap between a ADFm and EJB is not acceptable, as the search MAY limit the user in acquiring the information he (or she) is not able to describe in adequate manner based on search criteria offered by the developer. So, the developer may be responsible for misinformation of user, by limiting his access to information, jus for technology limitations of ADFm which forces a development of purely SEARCH-based functionalities.
I hope that development team would appreciate and consider this remarks, and invest effort in closing (not bridging!) the gap between ADFm and EJB.

Bind an inputFile value to a data control methods parameter

Hello I am trying to create a InputFile (ADF Faces) which is linked to a data control method. The method reads a specified file and returns the content which is then displayed in table form.
 
I have a filereader Class with the following method:
public List<FileInQuestion> returnFileContents(String fileName)
 
I have created a data control based on this Class. From the JSF page, under the data control palette I can drag on may parameter 'FileName' (as input text) and my method (as command button) and finally the return type 'FileInQuestion' (as read only table). This all works fine and when I type a filename in and hit the button it displays the contents in a table.
 
Now the problem is that I want to base the input parameter on the value of the InputFile component. But when I drag and drop the 'fileName' parameter onto the canvas, it doesn't give me the option to create as an input file!
 
Please could someone tell me how I manually link (bind) the inputFile component to the 'fileName' parameter?
 
Sorry if a bit long winded!!
 
Thanks Dan

Thanks Frank but I need to get at the text value returned from the inputfile component. I did what you said with the following results:
 
I started with a inputtext field, command button and read only table. When I entered a value (in this case 'C:\data\contacts.txt' ) into the inputtext field and hit the command button the table displayed the expected results (for logic please see my 1st post).
 
I then convert the inputtext component to a inputfile component in the way you suggested. I now rerun the application, browse to the same file and hit the command button, and then nothing!! no results.
 
I'm I missing something here?
 
Thanks

Base Line date issue

Hi Experts,
I have an issue on base line date.
We have uploaed Vendor Open item cutover data through LSMW in foreground mode. After uploaed we found that the base line date 30.07.9999 is automatically picked wrongly in some of vendor open items. Some of the vendor items with same payment term is picked baseline date correctly. I have corss checked in LSMW upload fields and upload excel file and also i have checked in LSMW constant values and any field mapping for baseline date but there is no such mapping and constant values in the LSMW.   If i make manual posting of the same vendors its fetching the correct base line date.
now the issue is how to identify the cause, is it uploaed through lsmw or manual input because client is asking how it is picking defaul 9999 year. Is there any way to identify through FI Tables.
Kindly suggest some solution.
Thanks in Advance.
regards,
Surendra.

Hello Surendra,
The baseline date is controlled by your terms of payment and in
customizing the transaction is OBB8. You have four choices ->
No default - Indicator that no default value is required for the
             baseline date for payment. You then have to enter the base
             date manually during document entry.
Posting date - Indicator that the posting date is to be proposed in the
               base date field during document entry.
Document date - Indicator that the document date is to be proposed in
                the base date field during document entry.
Entry date - Indicator that the entry date is to be proposed in the
             field "Base date" during document entry.
The system will not re-determine the baseline date if the posting
date is changed. Similarly, if the invoice date is changed and the
baseline date is based on the invoice date, it will also not be
re-determined once enter is pressed.

How can I create a query with web service data control?

I need to create a query with web service data control, in WSDL, it's query operation, there is a parameter message with the possible query criteria and a return message contains the results. I googled, but cannot find anything on the query with web service. I cannot find a "Named Criteria" in web service data control like normal data control. In Shay's blog, I saw the topics on update with web service data control. How can I create a query with web service data control? Thanks.

Is it possible to save / extract data from a MS SQL database 2008 using lookout 6.2?

Is it possible to save / extract data from a MS SQL database 2008 using lookout 6.2?
Now a days we are saving / extracting data in a excel spreadsheet, but we would like to do that using a database because it is better.

You can use ODBC connection to work with SQL Server database.
Use SQLExec object to execute the SQL statement. Here is a KB about the SQL statement.
http://digital.ni.com/public.nsf/allkb/4ADEEA04CD24AE0B862565E20002A16F?OpenDocument
To write data to spreadsheet is more straightforward because Lookout has built-in spreadsheet object. But you need to write SQL statement by yourself to interact with other database.
To read the data back is the same way. Just use "select" SQL statement to query. You can use Datatable object to query.
The "Data Source" can be "DSN = data source name;". The data source name is configured in Control Panel->Administrative Tools->Data Sources(ODBC).
