DataBindings.cpx and DataControls.dcx

Regarding DataBindings.cpx:
http://iasdocs.us.oracle.com/review/11g_planning/reviewlib/web.1111/b31974/bcdcpal.htm#insertedID4
If I have a project where I've created a bounded taskflow with fragments and I have my own AM data control, then I deploy this project as an Adf lib and a consumer takes my lib, references my task flow as a region, would the consumer need to update their DataBindings.cpx to have a reference to my AM data control?
If so, anything else?
I was comparing my project with someone else's and noticed I didn't have a DataControls.dcx. Is this needed? Is there a way to regenerate this?
Using the following:
Studio Edition Version 11.1.1.0.0
Build JDEVADF_MAIN.DROP5_GENERIC_080123.2233.4835
What's happening is that the consumer is getting a NPE in findDataControl from the producer when the producer's taskflow is trying to reference the producer's AM data control:
Caused by: java.lang.NullPointerException
at oracle.adf.model.binding.DCBindingContainer.findDataControl(DCBindingContainer.java:1343)
Options I've tried:
1. Updated consumer's DataBindings.cpx to reference the producer's AM data control that was provided in producer's jar.
This worked but doesn't sound right, seems like a workaround.
2. Updated adfm.xml to reference producer's DataBindings.cpx
Error that reference to the producer DataBindings.cpx was not found in the consumer's project output directory.

Ron,
reading the specs it says that databindigs.cpx files of a ADF library need to be located in the META-INF directory of the deployment. So in general, the expected behavior is that you don't have to configure this. As it seems that you are Oracle internal, I suggest that you create a testcase and file a bug for development to have a look.

Problem in Moving DataBindings.cpx and DataControls.dcx

I tried to move the two files DataBindings.cpx and DataControls.dcx to another folder (ie. from default folder adfmsrc/taskform to adfmsrc/taskform/formA ), I changed the *"Package"* property in each file, and modified *<DataControlRegistry>* tags in adfm.xml to pointing to the new paths, and redployed the task form.
But when I log in the worklist app, my task form showed me an error that it failed to find my DataControls.dcx from the original folder (ie adfmsrc/taskform ).
Could anybody tell me what other changes are required? Thanks in advance.
Ps: I am using version 11g, 11.1.1.2.0

Problem sovled:
Forgot to change the *<dataControlUsages>* tag in DataBindings.cpx :(
Thanks for viewing :)

Where i can find DataControl.dcx file ?

hello ,
when i was use EJB 3.0 as business component i could easily find DataBindings.cpx and DataControls.dcx in view folder .but when i used ADF BC as business component i am only able to see DataBindings.cpx in view folder .is any one have any idea ?

From the Fusion developer guide:
+"The DataBindings.cpx file is created in the user interface project the first time you drop a data control usage onto a web page in the visual editor. The DataBindings.cpx file defines the Oracle ADF binding context for the entire application and provides the metadata from which the Oracle ADF binding objects are created at runtime. It is used extensively by the ADF Library Resource Palette browsing implementations, and also by the .cpx and .dcx design time and runtime merge and discovery. When you insert a databound UI component into your document, the page will contain binding expressions that access the Oracle ADF binding objects at runtime.+
+If you are familiar with building Fusion web applications in earlier releases of JDeveloper, you’ll notice that the.cpx file no longer contains all the information copied from the DataControls.dcx file, but only a reference to it. If you need to make changes to the.cpx file, you must edit the DataControls.dcx file.+
+The DataBindings.cpx file appears in the /src directory of the user interface project. When you double-click the file node, the binding context description appears in the XML source editor. (To edit the binding context parameters, use the Property Inspector and select the desired parameter in the Structure window.)"+

Add DataControl to DataBindings.cpx without a wizard?

Is it possible to add DataControl based on BC4J AppModule to DataBindings.cpx file without running one of the create new panel/frame wizards? For ex.: I created few BC4J AppModules but JDev didn't create DataControl elements in DataBindings.cpx and doesn't provide ability to edit it manually.

I have the same question. How do I 'manually' insert app module as data control in cpx file?

ADF BC : Ant and XSLT to modify bc4j.xcfg and DataBindings.cpx

hi
Before I deploy my ADF BC / ADF Swing application I would like to use Ant to make some changes to bc4j.xcfg and DataBindings.cpx
(see also "Defining ADF Business Components Runtime Properties for ADF Swing Applications" in the JDeveloper documentation)
I would like DataBindings.cpx to point to the correct configuration and bc4j.xcfg to only contain the configuration information that is required.
I created some XSLT transformation stylesheets to help me with that, see this example application:
http://verveja.footsteps.be/~verveja/files/oracle/AntXsltConnectionSwitchStuff-v0.02.zip
question
Does JDeveloper itself provide any features to automatically make changes to DataBindings.cpx (and bc4j.xcfg) before deployment?
many thanks

JDev10g and DataBindings.cpx

Hello,
we have several problems with the cpx and the MyXyzPanelUIModel.xml files. In general we appreciate the xml on the client. But in the current state it seems almost unusable.
1. 10g creates "DataBindings.cpx" instead of "<prj_name>.cpx". This prevents us from seperating the client tier into several projects because "DataBindings.cpx" must be unique on the classpath. The Online-Help chapter "About the Client Project Configuration File" says that the cpx name is derived from the project name (like in 9.0.3).
2. JClient Form Wizard generates a code line
mgr.loadCpx("DataBindings.cpx", map);
in the main class. loadCpx parses the cpx and creates a database session for each data control node (application module). Is this really the wanted behavior for a JClient application? Create N sessions even if a special end user only works with one data form (because he has restricted access rights in the applaction).
3. Only the first data form in a JClient project can be executed. Trying to execute a second data form results in a JBO-25003 exception:
(oracle.jbo.NoObjException) JBO-25003:
Object MyXyzView of type View Object not found
Regards
M. Thal

3. Only the first data form in a JClient project can be executed. Trying to execute a second data form results in a JBO-25003 exception:
(oracle.jbo.NoObjException) JBO-25003: Object MyXyzView of type View Object not found
We just used the wizards to perform the following steps:
- create a new workspace
- create a BC4J-project containing some entities, views and at least 2 application modules
use different views as data model
- create an empty project for the client
- create a Swing/JClient for ADF Form
Step2: choose Form Layout "Table"
Step3: create a new Data Model Definition for the first application module
(DataBindings.cpx contains one DataControl node)
- compile and run --> OK
- create another Swing/JClient for ADF Form
Step2: choose Form Layout "Table"
Step3: create a new Data Model Definition for the second application module
(DataBindings.cpx now contains two DataControl nodes)
- compile and run --> JBO-25003 (view not found)
The first generated form still executes ok. The exception occurs in the jbInit method of the panel class:
tableMyXyzView.setModel((TableModel)panelBinding.bindUIControl("MyXyzView", tableMyXyzView));
Using Form Layout "Single columns (label left)" throws an exception, too. Not sure: either the same or JBO-25058 (attribute not found).
It seems that only views and attributes from the first application module can be accessed.
Now the following steps corrupt the cpx:
- create a third Swing/JClient for ADF Form
Step2: choose Form Layout "Single columns (label left)"
Step3: select the first Data Model Definition from the list
Step6: choose another package name, use the same form and panel class names as for the first data form
- compile and run --> OK
But running the first data form results in:
JBO-29000: Unexpected exception caught: java.lang.NullPointerException, msg=null
The cpx "Containee" node of the first data form (using a table) has been replaced by a reference to the new package (using text fields).
The containee id "PanelMyXyzViewUIModel" is not unique in the project scope. The test case requires references for myPackage.PanelMyXyzViewViewUIModel and myOtherPackage.PanelMyXyzViewViewUIModel.
Hope this helps.

Update -Graph and Pivot Table model.DataControls.dcx of type null not found

Now Solved.
I upgraded to the new Jdeveloper release and the Preview works.
Update
I created a new application and the graphs work ok.
Now, why in my current project won't the graphs work???
Chuck
This just occured today 6/22/09.
When ever I preview a graph or pivot table i receive this message:
oracle.jbo.NoDefException: JBO-25002: Definition model.DataControls.dcx of type null not found
I drop the query on a form as a table and it works fine.
I have used Graphs before, and ahve never recieved this error.
I just remenbered, I was using the previous release of Jdeveloper when I built the graphs.
Probably nothing !!
In the developers manual this message is mentioned:
+29.3 Correcting Simple Oracle ADF Runtime Errors+
Failures of the Oracle ADF Model layer cannot be detected by the JDeveloper
compiler, in part because the page’s data-display and method-execution behavior
relies on the declarative Oracle ADF page definition files. The Oracle ADF Model layer
utilizes those declarative files at runtime to create the objects of the Oracle ADF
binding container.
To go beyond simple schema validation, you will want to routinely run and test your
web pages to ensure that none of the following conditions exists:
+■ The project dependency between the data model project and the user interface+
project is disabled.
By default, the dependency between projects is enabled whenever you create a
web page that accesses a data control in the data model project. However, if the
dependency is disabled and remains disabled when you attempt to run the
application, an internal servlet error will be generated at runtime:
oracle.jbo.NoDefException: JBO-25002: Definition
model.DataControls.dcx of type null not found
To correct the error, double-click the user interface project, and select the
Dependencies node in the dialog. Make sure that the ModelProjectName.jpr
option appears selected in the panel.
I checked and the model.jpr is there.
I re-installed jdeveloper but the same error occurs.
I have no idea on how to proceed.

Well, Shay
I search my entire C drive for datacontrol.dcx and *.dcx and no files found.
I am usiing ADF.
The new application that I created that works in preview does not have this file.
I unstalled jdeveloper, downloaded a new copy, deleted Oracle directory, installed jdeveloper and results are the same.
Is the datacontrol.dcx file the same as the "datacontrol in the Data Controls Folder "?
The datacontrol is present the Data Controls Folder (model.jpr model.appmodule)

Adding the dependency in the ViewController fixed this for me.
I'm using two AppModules in the controller and the second one wasn't being picked up.
I was able to fix this by:
Go to the Project Properties, select Dependencies, edit the Dependent Projects and Archives, find the model that's failing and add a tick in the Build Output box.
The model should now be picked up in the ViewController's DataBindings.cpx source file, though I did have to restart JDev for this to be picked up.

but when you run by the browser window , it will be OK!

DataBindings.cpx - Parameters

Can anyone tell me how to set the in DataBindings parameter's value in the run time? I overwrite datacontrol factory calss and set it to take 1 parameter, the default value of that parameter can be set in this DataBindings.cpx file, but how about at run time?
Thanks
Kun

Hi,
quoting one of our developers:
"You will need to place any variables that you need to access in the datacontrol factory in either the BindingContext or in some namespace that is el-reachable. Then you can access them using an el-expression or using the BindingContext.get().
Make sure however that if you put some stateful or resource objects in the BindingContext that you also clean it up appropriately using BindinContext.remove()"

How to change default encoding in DataBindings.cpx

Hello,
How to change default encoding in DataBindings.cpx,
on windows-1251 for instance?

I've filed Bug# 3147045 for this. Our DataBinding.cpx file and UIModel XML files seem to be getting hardcoded to use the ISO-8859-1 encoding. Our ADF Business Components XML files correctly pickup the IDE encoding.

Is this a known issue.?

Migration issues with DataBindings.cpx Jdev 10.1.2 to 10.1.3

Hey Guys,
I have had a look at the docco for migrating between JDeveloper 10.1.2 and 10.1.3 in relation to the databindings.cpx file with no luck. Anyway, with no changes other than the migration, the deployment will fail because it cant find the databindings file:
oracle.jbo.NoDefException: JBO-25002: Definition DataBindings.cpx of type Application Definition not found
Web xml with this error:
<context-param>
<param-name>CpxFileName</param-name>
<param-value>DataBindings</param-value>
</context-param>
So, i copied the bindings file to the view package which is standard for new applications created in 10.1.3 but then get this error message:
oracle.jbo.InvalidDefNameException: JBO-25004: Definition name view/DataBindings.cpx for type Application Definition is invalid
Web xml with this error:
<context-param>
<param-name>CpxFileName</param-name>
<param-value>view.DataBindings</param-value>
</context-param>
Any help would be appreciated because a simple migration solution is required in order for us to use the new version on existing apps.
Cheers Dave

[JHS10.1.3] incomplete generation of DataBindings.cpx

Hi,
I want to have another project after creating application by JSF ADF-BC template(remove original ViewController project and add a new one). But still use same Model project.After I add a new web project and run JHS generation,I found that DataBindings.cpx cannot be generated sucessfully.Only
<?xml version="1.0" encoding="UTF-8" ?>
<Application xmlns="http://xmlns.oracle.com/adfm/application"
version="10.1.3.36.73" id="DataBindings" SeparateXMLFiles="false"

are generated.
Instead of using Application template, I try to create projects on my own.
If I create a new web project and a new Business component project and run JHS generation,and then run one of these generated pages.I got
500 Internal Server Error
java.lang.NullPointerException at javax.faces.webapp.FacesServlet.init(FacesServlet.java:144) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpApplication.loadServlet(HttpApplication.java:2231) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpApplication.findServlet(HttpApplication.java:4617) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpApplication.findServlet(HttpApplication.java:4541) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpApplication.getRequestDispatcher(HttpApplication.java:2821) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.doProcessRequest(HttpRequestHandler.java:740) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:451) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.serveOneRequest(HttpRequestHandler.java:218) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:119) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].server.http.HttpRequestHandler.run(HttpRequestHandler.java:112) at oracle.oc4j.network.ServerSocketReadHandler$SafeRunnable.run(ServerSocketReadHandler.java:260) at oracle.oc4j.network.ServerSocketAcceptHandler.procClientSocket(ServerSocketAcceptHandler.java:230) at oracle.oc4j.network.ServerSocketAcceptHandler.access$800(ServerSocketAcceptHandler.java:33) at oracle.oc4j.network.ServerSocketAcceptHandler$AcceptHandlerHorse.run(ServerSocketAcceptHandler.java:831) at com.evermind[Oracle Containers for J2EE 10g (10.1.3.0.0) ].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:298) at java.lang.Thread.run(Thread.java:595)
Finally, I found a way to add my new project.
I use JSF ADF-BC template and again remove original ViewController project.
And then I add a empty project and add a new JSF JSP page within it.
After creating business components and running JHS generation , it works !
Any ideas about this ?
Thanks

Databinding.cpx and Plugins

Hello,
I use JDeveloper 10.1.3 and I want to have multiple Databindings.cpx for a Swing JClient project.
I have currently a core Application with one Databindings.cpx. Now I want to be able to extend this core application with multiple plugins. It is very essential that the core application works without any plugin.
So I've created an extra project in my Application for each plugin. Since some plugins provide windows that use ADF Databinding the plugin projects have Databindings.cpx files too. On Designtime this is no problem but during Runtime the Databindings.cpx of the plugins doesn't get found, although I've changed the filename of the cpx file and provided this new name to mgr.loadCpx() method call.
I've already searched the forum and the only possible solution for 10.1.3 (upgrading is not possible) seems to be merging the cpx files. For the few plugins now it may be an option (a pretty pretty ugly one. Almost as bad as Spaghetti code) but it may be impossible to use later when I have a huge amount of plugins.
Isn't there another solution? The content of the core cpx file needs to be registered somewhere. Why can't I add manually additional entries?
regards
joerg
P.S.
It is very anoying that there is no javadoc for the loadCpx method. Ok, it is generated by JDeveloper but how should a Developer understand the code when there is not javadoc?

Joerg,
Is [url http://technology.amis.nl/blog/?p=653]this blog entry of any help to you?
Best,
John
