Customize faces managed bean loading in ADF ( in JDev 11.1.2.1)

Hi there,
I am trying to use Spring with ADF. The intention is to use Spring context managed beans to use as backing beans in ADF.
I created a simple bean class. Created Data control based on it and tried to look at factoryClass, which is responsible for instantiating the bean class, oracle.adf.model.adapter.DataControlFactoryImpl.
Where in ADF it creates the instances of backing beans? What is the best approach to solve this puzzle?
With regards,
- Manoj

I don't think your version of Jdeveloper supports CDI beans. It is my understanding that CDI beans will be supported next year in Jdeveloper.
So for now, if you are using Jdeveloper, you are stuck with only JSF managed beans that need to go in the faces-config.xml files or managed beans annotations .....

Accessing facade bean in ADF Faces managed bean

Hello
I am trying to display data from a database on a page using ADF Faces. I am using a Web Application [JSF, EJB] template in JDeveloper with the model project using JPA entities with a session facade bean to manage the entities (as described here: http://www.oracle.com/technology/obe/obe1013jdev/10131/ejb_and_jpa/master-detail_pagewith_ejb.htm ).
What I have tried to do is to set up a managed session bean in the ViewController project that is referenced by a faces page. The managed bean is supposed to, on creation, load data from the database into managed properties which are then displayed on the faces page using EL references. I want all JPA management to go through the facade, and thus I want to inject the facade bean into the managed bean using @EJB notation. However, the injection does not work, and all I get is a NullPointerException when trying to access the injected facade in the managed bean.
I have also tried instantiating the facade bean in the managed bean's constructor manually, but when I try to call a method on the facade, I get another NullPointerException, this time from the entity manager which obviously is not injected into the facade bean.
What is strange is that the facade bean works perfectly when I use the datacontrols generated from the facade bean, as described in the tutorial (no exception from the entity manager).
I have searched high and low for a solution to this, and from what I can read, it should be possible to do what I want (see for example https://blueprints.dev.java.net/bpcatalog/ee5/persistence/ejbfacade.html and http://luxlog.wordpress.com/2007/12/15/basic-example-web-app-with-glassfish-netbeans-60-jsf-and-ejb3/ ). I found someone mentioning that dependency injection in the web container OC4J was added after a given version, and that web.xml needs to be upgraded to version 2.5, which I have done but did not solve anything.
Is this not possible in JDeveloper/OC4J at all? Is there any other way to access the facade session bean in managed beans?

Hi,
for resource injection you need JDeveloper 11. Here the EJB annotation works to inject the resource. If you want to do similar in 10.1.3 then you need to do a JNI lookup in the managed bean (under the shelves ADF does the same)

ADF Faces: Managed Beans

Hi All,
I have a situation where i need to pass the value to managed bean at runtime which inturn changes the values of menubar,menulist please can any one help me out.
Regards
Manasa Chanda

What you probably want to do is expose the menubar.menulist component to your managed bean. This is fairly easy to do by editing the "Binding" property of the component. This will let you specify a Managed Bean, and a Property, or you can press a New button to create the bean, and/or the Property. Once you've exposed the component, the properties of the component are available through EL, including being able to change those properties from other components.

Manage bean for pop up getting called when parent screen is getting loaded

Hi,
I have designed two jspx . One having pop up code and other one (parent) from which the pop up will open. Problem is after I have put the pop up code in my Perent screen both the manage beans are getting invoked when parent screen is getting rendered which i dont want . Please help me out regarding how to avoid this?

where did you register the managed Beans ?
Which version of Jdev do you use ?
Also how did you include your popup code in the jpsx - by jsp include or by using regions ?

How to get iterator values from a managed bean ?

Due to a bug in selectOneChoice i'm not able to get the label list i want to display directly from an iterator when the value binding is a managed bean.
To solve the problem i would like to create a managed bean that contains that list and use it as the selectItems to display.
I would like that the values in that managed bean loaded from the a data control iterator.
My question is :
1) is it possible to access the iterator values from a managed bean, i mean without any reference to a page definition
2) how to do ? is it documented somewhere ? any example ?
Thank you

Managed Bean in Task Form

Hi!Oracle Fusion Middleware 11.1.1.5.0, Oracle JDeveloper 11g.
I post this thread in this section because of the type of project I am working in (SOA Application).
I am trying to customize a BPEL Task Form.
After I made a project using Fusion Web Application, I could confirm that the managed beans for some ADF Faces components were working and the form (an .jspx page that I would run on Integrated Web Logic Server) was functional.
I made a project using SOA Application.
I made a BPEL Process with a Human Tak and using the Launch Task Form Wizard I made a form.
Then I started adding ADF Faces components that are using managed beans, just like in the other project.
When I deploy the project, all the components using the beans just dont show up. If I dont use the components with the managed beans the form appears normally.
Is there some additional requirement to make the bindings with the managed beans in the Task Form?
To clarify the question below I have some printscreens:
1. SelectOneChoice "Rubrica" component with value binding from the ActionListenerOK java class;
http://i43.tinypic.com/x4j0ol.jpg
2. Showing the Expression Builder for the above value binding;

3. Method Expression Builder for a Button Component;
http://i41.tinypic.com/2r38tw2.jpg
4. The managed beans list for the form page;

5. How the form appears when using the components with java bean bindings;

ADF Faces: How to get the ADF BindingContainer in a managed bean?

Hi,
I not sure how to get the BindingContainer instance from inside of a managed bean method. I have tried the following config, but it does not work in all situations.
<managed-bean>
    <managed-bean-name>backing_showBooks</managed-bean-name>

    </managed-property>
    
</managed-bean>When an ActionListener- method of my ShowBooks bean is called the property bindingContainer is NULL!!
Is there a save way to get the BindingContainer in my bean??
Any hints are welcome.
Thanks,

Managed bean/Data exchange between two ADF Rich Faces based applications

Hi,
I have been trying to research what seems to be a small issue. My requirements are as follows.
1. I need to be able to pass managed bean information from one ADF Rich Faces based application to another (in two separate ears) at runtime (e.g. from Ear1: SenderApp/Sender.jspx -> Ear2: ReceiverApp/Receiver.jspx).
2. I do not want to use the database as my applications need to be performant.
3. Serialization/de-serialization would fall pretty much under the database category. In other words, I like to avoid Serialization/de-serialization of the managed bean.
4. I cannot use query string due to security issues.
My question is as follows:
1. Is there any standard/architecture/best practices for data exchange of backing beans or other forms between two ADF Rich Faces based apps (in two separate ears)?
2. Has someone found anything similar to an applicationScope that works across applications?
I would appreciate any ideas.
Thanks very much,

Hi,
its not an ADF Faces problem, but not possible in Java EE. You can however fallback to vendor specific implementations like in WLS. From the WebLogic documentation : http://e-docs.bea.com/wls/docs103/webapp/sessions.html
Enabling Web applications to share the same session*
By default, Web applications do not share the same session. If you would like Web applications to share the same session, you can configure the session descriptor at the application level in the weblogic-application.xml deployment descriptor. To enable Web applications to share the same session, set the sharing-enabled attribute in the session descriptor to true in the weblogic-application.xml deployment descriptor. See “sharing-enabled” in session-descriptor.
The session descriptor configuration that you specify at the application level overrides any session descriptor configuration that you specify at the Web application level for all of the Web applications in the application. If you set the sharing-enabled attribute to true at the Web application level, it will be ignored.
All Web applications in an application are automatically started using the same session instance if you specify the session descriptor in the weblogic-application.xml deployment descriptor and set the sharing-enabled attribute to true as in the following example:
+<?xml version="1.0" encoding="ISO-8859-1"?>+
+<weblogic-application xmlns="http://www.bea.com/ns/weblogic/90";;>+
+...+
<session-descriptor>
+<persistent-store-type>memory</persistent-store-type>+
+<sharing-enabled>true</sharing-enabled>+
+...+
+</session-descriptor>+
+...+
+</weblogic-application>+

ADF Faces and BC: Scope problem with managed bean

Hi,
I am using JDev 10.1.3 and ADF Faces with ADF BC.
I have created a managed bean which needs to interact with the binding layer and also receive actions from the web pages. I have a managed property on the bean which is defined as follows:
<managed-bean>
    <managed-bean-name>navigator</managed-bean-name>
    <managed-bean-class>ecu.ethics.view.managed.Navigator</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
      <property-name>bindings</property-name>
      <value>#{bindings}</value>
    </managed-property>
</managed-bean>I need the been to session scope because it needs to keep previous and next pages to navigate the user through their proposal. If i use session scope (as above) i get the following error when i click on a comand link which references a method in the above bean: #{navigator.forwardNext_action} which returns a global forward.
this is the exception:
javax.faces.FacesException: #{navigator.forwardNext_action}:
javax.faces.el.EvaluationException: javax.faces.FacesException:

Hi pp,
you need to create a managed (not backing) been set to session scope.
You can call/reference the managed bean from your page.
the backing bean is designed around a page lifecyle which is request oriented in it's design.
This is a simple managed bean from faces-config.xml
<managed-bean>
    <managed-bean-name>UserInfo</managed-bean-name>
    <managed-bean-class>ecu.ethics.admin.view.managed.UserInfo</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>
</managed-bean>and the getters and setters for bindings in your session scope managed bean:
    public void setBindings(BindingContext bindings) {
        this._bindings = bindings;
    public BindingContext getBindings() {
        return _bindings;
    }you can access the model from the managed bean using the the BindingContext if needed.
also have a look at JSFUtils from the ADF BC SRDemo application, there are methods in this class such as resolveExpression which demonstrate how to get the values of items on your page programatically using expression language. You can use this in your managed bean to get values from your pages.
regards,
Brenden

Adf faces: execute bean method after table is loaded

Hi,
How can I execute a method after an adf table is rendered on the page?
This is what I want to do:
I have a master/detail:
- the master part contains a list of materials
- the details contains a list of customers and volumes depending on the selected material.
I tried to add totals on the details table:
- I created an output text in the footer-facet of the colums containing volumes
- I created a binding of the detail table to a CoreTable.
- I created a method in a managed bean related to this CoreTable binding, so I can browse to all rows in the table and calculate the sum.
- I then set the value of the output text to the total calculated in the managed bean.
the problem is that I don't know how to execute the calculate procedure after the data in the detail table exists.
What I tried:
- call the calculate procedure in the setCoreTable method. --> at this point, there is no data in the table and this results in a nullPointerException when the pages is loaded.
- call the calculate procedure on the valueChangeListener of the material list --> this doesn't work because totals are calculated for the previous details set.
- I tried to add the call in one of the table listeners but I cannot find a listener that is executed after data is loaded in the table...
for testing purpose only, I added a button: calculateTotals that calculates the totals. This works correctly.

Hi,
if you use page fragments exposed in an ADF region, you have two options I see
1. Use a method call activity to call the managed bean
2. Use a hidden UI component that references the setter/getter exposed in a managed bean and just use this as an indication for the page fragment being loaded

How can I load the data of Manager Beans into an Array?

Hi all!
I have a problem when use the ADF model layer (JDeveloper 10g). I want to load the data of a Manager Bean into Array(such as: Array in JavaScript).But I don't know any ways to do.
Are there any ways to do that?
Please, help me!
Thanks so much!

Hi,
there is a fundamental difference between an array in Java and an array in JavaScript as the latter is added to the output page while the first sits in a Java class on the server.
Populating a Java array from a managed bean is straight froward: Just create the Array, loop through the source of the data - ADF binding or the ADF Faces table component - and fill it.
For a JavaScript Array I would suggest to write the array into a js file and reference it from the web page (which might cause concurrency issues).

How to access backing bean of a xml component , in a managed bean of ADF

Hi,
We wrote a xml component in JSF and this component is used in ADF project by including the component as jar .
In a master detail page , we need to update the value of the xml component, when the master row is changed. How to do this.
We are trying to do this by accessing the backing bean of the xml component in ADF project's managed bean. So when ever the row changes, we can access the managed bean in ADF and then can set the value of the xml component by accessing it's backing bean
But i can't access the backing bean instance of the xml component in the ADF managed bean. Could you let me know how to do this. Thanks .

Thanks for the response Shay. The xml component is added as a custom component , with a separate faces-config.xml file . This component is added to ADF project as a jar with a custom tag.
In the ADF project , i'm having different managed beans and i can access them from a different managed bean.
The issue is, i can't access the added custom component's backing bean which is available from a different jar , defined in a separate faces-config.xml file . This backing bean is defined with request scope.

Howto: Iterate ADF BC from a managed bean from the View?

Hi Everyone,
I've been trying to iterate a BC ADF object from a managed bean from the view layer. Here is what I have done so far, but I don't seem to get any records:
In faces-config.xml, I am passing in the BindingContext to the managed bean. (This is a session scoped bean).
<managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>In the testPageDef.xml I have the executables and bindings setup:
<executables>
    <iterator id="TestRO1Iterator" RangeSize="-1" Binds="TestRO1"
              DataControl="ApplicationControlDataControl"/>
</executables>
<bindings>
    <table id="TestRO1" IterBinding="TestRO1Iterator">
      <AttrNames>
        <Item Value="C1"/>
        <Item Value="C2"/>
      </AttrNames>
    </table>
</bindings>In my managed bean, in addition to the accessors for the bindingContext of bindings, I have:
             BindingContainer bc = getBindings().findBindingContainer("testPageDef");
             ControlBinding cb = bc.getControlBinding("TestRO1");
             RangeBinding rb = (RangeBinding)cb;
             List testList = rb.getRangeSet();
             Iterator testIter = testList.iterator();
             int testCount = testList.size();
             while (testIter.hasNext()) {
               Map attrs = (Map)testIter.next();
               System.out.println(attrs.get("C1")+","+attrs.get("C2"));
               //Do some fancy stuff here with the values.
             }However, my testList.size() always returns 0.
Is this the right method to programatically access the data from the view layer from a managed bean, or have I missed something completely? Are there any working samples that I could take a look at?
Jdev: 10.1.3.1
Thanks!

Hi,

You find several examples in the developer guide and on the Internet

Managed bean in both adfc-config.xml and faces-config.xml file

hi,
i can see that it's possible to declare managed bean in both adfc-config.xml and faces-config.xml file.
is there any difference? which one is recommended?
read here - http://www.jaypillai.com/tag/adf/
but still not clear.
thanks.

Hi.
As you know ADF is a framework based on JSF.
In faces-config.xml you define general application manage beans. It offers you define manage beans for all application using JSF default scopes (application, session, request).
In adfc-config.xml you define general application manage beans using ADF Scopes. It means that you can use JSF default ones including "view, pageFlow and backing".
My recommendation is use only one point entry for your general manage beans. Use adfc-config.xml because allow you to use more scopes.
Regards.
