Automatically Expose UI Components Using an Existing Managed Bean

I am trying to use the "Automatically Expose UI Components Using an Existing Managed Bean" in the Page Implementation" section when creating my jspx page but cannot figure out how to get the radio button enabled in order to use it.

Can you further describe for me? Here is my use case.
I have a page where I enter parameters that are sent to the session bean that calls the entity and returns a list.
This list is what I need to display on the next page.
I don't understand how to get the information from one page to the next. I did set the managed-bean-scope in the faces config to session.

Query with bind variable, how can use it in managed bean ?

Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
Thanks

Put the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page.

Binding ADF UI components to managed beans instead of using bindings

Hi All,
We are working on a ADF based development project and we have complex data input forms.
We have close to 200 input forms for different products and each form has different details.
Requirement is to store the data captured in the input forms as XML in database instead of storing the information in relational tables to avoid creating tables for each of the 200 products.
We are planning to capture user input in page flow scoped managed beans and when user save the data, generate the XML from managed bean data and store the XML string in DB using ADF BC.
So we would develop the UI more like a normal J2ee application using JSF where managed beans are used to collect data, and then use ADF BC for database persistence.
Is it a good practice to bind the managed beans to UI bypassing the bindings? (We can't use bindings as we store data in XML format).

Hi Alex,
That is not the right way to get the component, #{it1} is not valid.
Here is the sample code to get the component by id, but is not recommended as you should know the parent component ids as well and it would be difficult to maintain in long run:
FacesContext context = FacesContext.getCurrentInstance();
context.getViewRoot().findComponent("<id>")What is your exact usecase?
Any specific reason for not using binding property?

How to access all rows one by one of a ADF table through managed bean

Hi Experts,
Hi i am new in ADF.
Could someone help me for solving the below case?
Scenario - I have table called Test_T1 which have 4 columns C1,C2,C3,C4. Have created EO,VO and AM for test_t1.
At the time of ADF page creation i selected the option 'Automatically Exposed UI components in New managed bean' (mynewmanagedbean.java).
From Data control drag and drop Test_T1 table in the page as a ADF table.
Set the properties for C1,C2,C3 is read only and C4 is an input text.
Have add after the table and attathed button action on the managed bean mynewmanagedbean.java.
At the time of running the page Test_T1 populated with some no. of rows (like 9).
How can i access all the above rows through pressing the button without selection of any of them.
Actually i want to print all the table rows in log file at the time of pressing the button.
Thanks in advance.

Hi Timo,
Thanks a lot for your reply.
I am using the JDeveloper 11.1.2.1.0.
As previously said I am totally new in this framework. So if you explain the solution given by you then it will be help full for me.
Don't know r you agree or not for this ?
When i put your resolution in the command button bean JDeveloper said TestDataRow type not found.
What will be the type and TestDataRow and what is missing in below code or how i will declare that in below code?
Also Could please mentioned the missing thing ?

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

JDeveloper gets slow with a lot of managed beans declared in faces-config

Hello,
I have an application with a lot of managed-beans (in fact, hundreds of backing beans). When I open the visual designer, it takes a long time to render the page, and after it gets very slow. Even the source view gets slow. When I remove some parts of these managed beans, JDeveloper back to normality.
The problem is that the JDeveloper is so slow that I just can not do anything in JSPs.
Anyone have any idea?
I am very grateful for any help.
Thanks.

ThDn,
You can avoid adding unnecessary getters and setters of UI components in backing bean by selecting the option "Do not automatically expose UI Components in a Managed Bean" option when creating the Page.
The nice thing is that in JDev 11g and in latest version of JDev 10g this option is selected by default when creating new pages.
However in older JDev 10g versions the default was "Expose UI Components to a Managed Bean" so if developer did not change it during page creation it is possible that there would have been lots of unnecessary getters and setters in the backing bean.
Luiz,
As you say that this was fine in TP4 it could be that in newer JDev version there might have been added some new feature that caused this slowness.
When you remove unnecessary getters/setters from you backing beans, you will have to modify the JSPs and remove the bindings from the UI components as well.
Thanks

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 .....
Yesh

Dynamic managed bean names

Hi!!
in my application i make code that must be present in every JSP pages. For that, i put it into a separated JSP page who is included in the other JSP (using <jsp:include> tag).
My problem is that each JSP who include the repetitive JSP, uses a different managed bean name.
For example, the page who is included is:
<f:subview id="navigation">
      <h:inputText value="#{name-of-bean.navigation}" styleClass="inputNav" readonly="true" />
</f:subview>When this code is included into the pages, each page must use a different "name-of-bean".
I try with:
<jsp:include page="navigation.jsp">
     <jsp:param name="beanName" value="AlfaBean" />
</jsp:include>and in the child JSP:
<h:inputText value="#{requestScope[param.beanName].navigation}"
styleClass="inputNav" readonly="true" />but dont work.
I try with:
<h:inputText value="#{resources[param.beanName].navigation}"
styleClass="inputNav" readonly="true" />but dont work.
Some body can help me??
PD: Sorry my bad english!!

JSF creates a managed bean at the time when firstly it evaluates the
corresponding value binding expression, such as "#{AlfaBean.someProp}".
Your JSP files include no expression including the name of the bean.
Although it may be a very tricky code, here is a sample used for you problem:<h:outputText value="" rendered="#{AlfaBean.someProp != null}"/>
<jsp:include page="navigation.jsp">
     <jsp:param name="beanName" value="AlfaBean" />
</jsp:include>

Specify factory for managed bean

Hello,
I'm new to JSF and find myself duplicating a lot of code. For example, I have several pages that display data in the exact same way, even though the data collections vary (i.e. one page displays Country instances; the other State instances). Right now, I'm creating a managed bean for each type, but the beans only differ in how they populate the data (i.e. the bean for Country knows to load its data from resource X, whereas the bean for State uses a separate resource). Is there a way to specify a factory for initializing beans, or a way to pass arguments to the constructor, so that I could just use a single managed bean, with my JSF pages specifying how they want the bean initialized (i.e. for Countries, rather then States)? Am I misunderstanding some thing about managed beans? Under a servlet app, I would just populate the bean and then forward the client- I'm struggling with how to duplicate that need in JSF. Thanks for your help. Take care.

Taskflow managed bean

Hi,
I'm using JDev11/ADF. I was wondering if I can have something like a taskflow managed bean with taskflow scope and use the same base class and the same bean name in two different taskflows, which one with it's all bean "instance".
Tks.

Hi,
I got the answer for this question. Here is the code which you need to use in your managed bean to refresh the taskflow.
BindingContext bctx = BindingContext.getCurrent();> BindingContainer bindings = bctx.getCurrentBindingsEntry();
> DCTaskFlowBinding taskflowBinding = null;
> taskflowBinding = (DCTaskFlowBinding) bindings.get("CompletedActionsTF1");
>taskflowBinding.refresh();
Thanks,

How to use an existing data model using Business Components in OEPE

I am a beginner in ADF. I am working on a project with an existing data model that uses Business Components (EO, VO and AM). I know that OEPE does not handle the creation of BC, so if I want to modify them, I will have to do that in JDev. That's fine.
OEPE can create pages with drag and drop like in JDev. In my eclipse ADF projects, I would like to use the existing BC, to be able to use the bindings with ADF Faces. So far I have nothing in the Data Controls tab.
How to import the BC into the Data Controls tab?
JDev 11.1.1.6
WLS 10.3.6
Eclipse Kepler

We currently don't support DataControls based on the ADF BC technology. We will consider such support if there is a strong interest in that use case.
Independent of the IDE's you use, there are ways to expose services based on ADF BC that can then be consumed by the view layer. A Google search will point you to some of the approaches.
HTH. Thanks for your interest in OEPE.

Installing Enterprise Manager 10g Grid Control Using an Existing Database

I want to install Enterprise Manager 10g Grid Control 10.2.0.3 using an existing database. This database is RAC 10.2.0.2. and I use it as Infrastructure Metadata Repository.
I is said in Oracle documentation that SYSMAN schema has to be dropped, thus Database console repository has to be dropped. As far as I understand after Grid Control installation I will not be able to use Database console for my RAC 10.2.0.2 Infrastructure Metadata Repository database. I will be able to use only Grid Control for this database.
Am I right? Could you give me any advice about Installing Enterprise Manager 10g Grid Control Using an Existing Database?

WADK components & setting used for power management with answer file for windows 8.1 ent

hello,
I have to deploy windows 8.1 ent device with MDT answer file related to power management with customized following settings:
High performances
sleep timeout settings
standby or sleep and hibernate setting
Enable critical battery task.
But don't know
1. how to manage power settings using answer file (WADK) for win8.1.
2. which OS Windows image component and setting used for power management in WADK.
Thanks
Richa Km

The way I do it with my task sequences (this works with MDT as well as SCCM) is to have an exported power plan using the POWERCFG -EXPORT command. I create a software package around the resulting *.POW file with a command do do an POWERCFG -IMPORT.
I then issue a POWERCFG -SETACTIVE command to the GUID of the *.POW file to enable that power scheme.
More information on the POWERCFG command can be found here:

How to use an existing remote database instance?

Hi,
is it possible to use an existing remote database instance for installation of Solution Manager?
Our dba has setup an empty database instance on a hpux oracle cluster for me and I don´t know how to tell the SAPinst during the installation of the distributed system that it should use this existing database.
Or is it mandatory to run the installation on the host where the database should resides and then create a new instance?
Thanks in advance for any hints!
