Creating Data Control Adapters

Hi,
I'd like to create custom data control adapter. Unfortunately, documentation I have found covers 10.1.3 version:
http://sqltech.cl/doc/oas10gR3/web.1013/b25386/advanced_adf_data_controls.htm
Why there is no documentantion to 11g ?
Kuba

Hi,
in JDeveloper 12c we provide a wizard for this. Not sure what your reason is for building your own adapter, but in the past people outside of Oracle only used POJO beans and never considered writing their own adapters. This is how it comes that there is no documentation. So 12c is the target for your requirement

Getting Extra classes while creating Data Control in ADF

I am using Jdeveloper 11.1.1.6.0.
I was trying to create a Data Control from a Java class (containing event handling code) right click on the java class -> Create data Control.
I can see many data controls were created in my work space when the operation was completed
Example: java.io.InputStream.xml, java.net.URI.xml and many more.
Anybody please suggest is it a problem in Jdeveloper tool or I need to perform any additional step to remove all these files.
Regards,
Rajesh

Hello TimoHahn,
I can see only the Data controls are getting generated (not the class files).
Please find the code snippet for my class for which I generated data controls:
public class ContexEvent {
    public ContexEvent() {
        super();
    public void handleEvent(ActionEvent payload){
        UIComponent component = payload.getComponent();
        Map<String, Object> attrMap = component.getAttributes();
        FacesContext context = FacesContext.getCurrentInstance();
        ELContext elContext = context.getELContext();
        Application application = context.getApplication();
        ExpressionFactory factory = application.getExpressionFactory();
        ValueExpression valueExpr = factory.createValueExpression(elContext, "#{backingBeanScope.NameBean}", Object.class);
        NameBean nb=(NameBean)valueExpr.getValue(elContext);
        //String newVal = (String)payload.getNewValue();
        nb.setFirstName("Rajesh");
        AdfFacesContext adfContext= AdfFacesContext.getCurrentInstance();
        adfContext.addPartialTarget(nb.getNameLabel());

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

Hence, I have two question
1. Can I create my data control from the bean interfaces instead of the bean?
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)

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

Create data control button missing from menu

I'm using Jdeveloper 11.1.2
1. I create a new Application
2. create a new JavaClass under viewController
3. right click the class
and...
I can't find the create data control button and create webservice button
I do the same operation on another computer , it appears !
why ?
is ther any settings I need to turn ?

If you do not bother about loosing your current IDE preferences then close/kill jdev and try deleting the jdev system directory. Start jdev again.

Create data control from java class, not see "ADF Parameter Forms" option

Hi,
I have created a Fusion Web Application (ADF) in jdev 11g. In the application model project, I created a java class. Inside the java class, I have a public method as below
public Asset [] searchAsset3(SearchTerm s) // SearchTerm is a java bean. It implements java.io.Serializable.
I created data control from my java class. After that, I see an xml file generated under the same folder of my java class. Here is the xml content.
<?xml version="1.0" encoding="UTF-8" ?>
<JavaBean xmlns="http://xmlns.oracle.com/adfm/beanmodel" version="11.1.1.53.62"
id="AIAAsset" Package="oracle.apps.aia.oer.model"
BeanClass="oracle.apps.aia.oer.model.AIAAsset" isJavaBased="true">
<MethodAccessor IsCollection="true"
Type="com.flashline.registry.openapi.entity.Asset"
BeanClass="com.flashline.registry.openapi.entity.Asset"
id="searchAsset" ReturnNodeName="Asset"
CollectionBeanClass="UpdateableCollection">
<ParameterInfo id="name" Type="java.lang.String" isStructured="false"/>
<ParameterInfo id="version" Type="java.lang.String" isStructured="false"/>
<ParameterInfo id="description" Type="java.lang.String"
isStructured="false"/>
</MethodAccessor>
<MethodAccessor IsCollection="true"
Type="com.flashline.registry.openapi.entity.AssetSummary"
BeanClass="com.flashline.registry.openapi.entity.AssetSummary"
id="searchAssetSummary" ReturnNodeName="AssetSummary"
CollectionBeanClass="UpdateableCollection">
<ParameterInfo id="name" Type="java.lang.String" isStructured="false"/>
<ParameterInfo id="version" Type="java.lang.String" isStructured="false"/>
<ParameterInfo id="description" Type="java.lang.String"
isStructured="false"/>
<ParameterInfo id="type" Type="java.lang.String" isStructured="false"/>
</MethodAccessor>
<MethodAccessor IsCollection="true"
Type="com.flashline.registry.openapi.entity.Asset"
BeanClass="com.flashline.registry.openapi.entity.Asset"
id="searchAsset3" ReturnNodeName="Asset"
CollectionBeanClass="UpdateableCollection">
<ParameterInfo id="s" Type="com.flashline.registry.openapi.query.SearchTerm"
isStructured="true"/>
</MethodAccessor>
<ConstructorMethod IsCollection="true"
Type="oracle.apps.aia.oer.model.AIAAsset"
BeanClass="oracle.apps.aia.oer.model.AIAAsset"
id="AIAAsset"/>
</JavaBean>
Then, in application user interface project, I created a JSPX page. From the data controls palette, I want to drag and drop the searchAsset3 onto my page. However, I don't see an option for me to choose "Create -> Parameters -> ADF Parameter Form". I only see "Create -> Methods". Unlike other public methods (e.g.searchAssetSummary and searchAsset) which have simple data type as input, I can see the "Create -> Parameters -> ADF Parameter Form" option when I drag and drop to my jspx page. Is that something I missed while creating data controls?
Thanks.
Arnold.

Then, my other question is how do you do the bindings? I drag and drop the attributes from SearchTerm bean. Now the pagedef file has the AttributeValues added but my method is actually expecting one input parameter of type SearchTerm. How do you bind the attributes to the input of the method? Thanks.
See below of my pagedef xml file.
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"

</executables>
<bindings>
<methodAction id="SearchTerm" RequiresUpdateModel="true"

(A little time ago, I have getting the error in thread : Null Pointer exception in ToplinkDataControlProvider but I have passed this error message) I tried to create xml file descriptions for POJO files. To do this, I have chosen "create data control" option but gotten the below error message in message window :
What can be the problem. I have controlled mapping file, there is no problem in mapping status also make and rebuild the model package there is no error message.

Create Data Control not showing in EJB Session Bean context menu

Hi All,
I've been studying the new Oracle Application Development Framework Tutorial for 10g Release 3 (10.1.3). When I get to page 2-16 (page 31 of the PDF doc) it says to create ADF Data Control. Specifically is says " In the Applications Navigator, right-click the SRPublicFacadeBean.java node and choose Create Data Control from the context menu."
But my context menu doesnt have the Create Data Control option. I double checked that I didn't miss a step in the tutorial. I'm sure it's something simple. Can anyone point me in the right direction? Is there another way to create the Data Control for an EJB Session Bean?
Thanks,
Cary

I downloaded "jdevstudio1013.zip " and I still don't have this context menu?
What are the steps to correct this?
Thanks,
--Todd
Figured it out. I was having an extension issue and I had to turn off all of my extensions. Thus, turned on the ADF extension (duh!) and all was well.

Create Data Control does not work?!

I created an application with JSF,EJB,TopLink JPA technology template.
Two projects were generated, EJBModel and View Controller. So far so good.
In EJBModel project I generated 6 entities from 6 db tables. I also created a native query in orm.xml and created a result class entity to take the result of this native query.
I generated session EJB facade and added a method to invoke above native query.
I also generated EJB client from this facade to test it.
I run both to ensure query works as expected and it did.
I then right clicked on session EJB facade and selected option Create Data Control.
JDev pop-ed up two windows: one window to Choose EJB Interface dialog and on top of this one another window with title "Create Data Control" and with message "Creating data Control..." stuck forever. I could not remove nor stop this window executing, I had to kill JDev in Task Manager.
Is this a known thing and is there a workaround? This is kind of urgent, any help is appreciated

I returned to 10.1.3.2. and created the same application, but got bunch of exceptions which forced me a couple of weeks ago to switch to 11g Preview environment:

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)

Problems to create data control in JDeveloper 11g

Hi everybody , I´m having problems to use Data Control in Jdev 11 , I create an jpa , and with my entities I create the data control component , but when I try to create a JSF page I can´t use data control, where is data control component palette ?

Please post JDev 11 questions on the JDev 11 forum

Follow this tutorial to see the data control palette for EJB/JPA

JDeveloper - create csv data control adapter

Oracle 10.1.3.4
Following tutorial of creating data control adapter. I can see the csv file in my System Navigator but 1) can't right click to select Create Data Control AND 2) can't drag and drop csv to data control pallete. According to oracle's documentation a simple CSV data control adapter ships with JDeveloper. I can see the contents of the csv and view data in JDeveloper but can't right click on csv file to get menu 'Create data control adapter'. My goal in making the adapter will allow me to use the csv as data source to create search form and then make local table for other forms.
Therefore, proceeded with following directions:
1) created dapter-definition.xml, extension.xml then added library files to properties and followed instructions to copy files in specific directories after creating jar file containing specific files but can't locate directory oracle/adfinternal/model/adapter/sample... for several of the needed files. Attempted to make directories with needed classes so references are not blank, not working or something missing.
In attempt to work around, located another oracle jar file that contains looks to be similiar CSV Handler$1.class, CSVHandler.class, CSVParser.class, but can't find SampleDataControl.class, SampleDCAdapter.class and SampleDCDef.class? As a result, copied code from tutorial and it's still not allowing me to right click on a this node type (CSV) and select Create Data Control.
Please advise!!

Thank you so much for your reply! =)
To answer your question, I was trying to create a new adapter because I couldn't find how to use an exising one. Sure, I'll try using the existing one as it looks like this wizard will allow me to use my spreadsheet or it can be a xml file. But note this file is local, located on my hard drive. I suppose I could move it to the server if I have to. Is there a way to do this with a local file?
Thanks again Frank

Not able to access SOAP web service data control from adf mobile

Hi,
I am trying to call web services from adf mobile..
I have created data control from external web service and it is perfectlly working on web browser..
But why it is showing an error on emulator??
Is there any .jar file missing in adf mobile so that it is not supporting a web service?
Or is there any other problem? Emulator is connected to network and I am able to run WSDL in emulator's browser..
Please help me to solve this issue..
Thanks,
Laxmi

Emulator is connected to network and I am able to run WSDL in emulator's browser..
Connecting to WSDL in the browser is not the same as connecting to WSDL in an application.
To access a web service from an Android device enable a permission in AndroidManifest.xml that allows applications to open network sockets. Add the following uses-permission element.
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

Should we really go for bean data controls for a new project?

Hi,
I am still new data controls and trying to figure out the advantages of using bean data controls for our new project. Our UI is going to have customized UI components and our back end is going to be a tcp/ip server.
Is it a good idea to develop java beans and then create data controls to bind to UI layer? I think it makes sense to use data controls if we want to use existing java beans. Maybe we would be separating the model layer by using data controls, but only thing it would be doing for us would be the simple object calls to my java beans. Would it be better to use data controls or use I choose to make object calls?
Thanks,
Manoj

Hi,
the POJO data control will always give you a benefit and develope productivity, unless what you have to build fits on a single page - in which case you may not mind the burdon of manual UI component binding
