Duplicate managed bean definition

Hello,
This is my first time to post on this forum and I am very excited :). Thank you all in advance for your time to read my post.
We are developing an EJB/ADF faces application using JDeveloper 11.1.1.4.0. When I deploy the application, I get the following message:
<MetadataService$Bootstrap> <add> ADFc: Duplicate managed bean definition for 'nameOfMyBean' detected.
<MetadataService$Bootstrap> <add> ADFc: /WEB-INF/adfc-config.xml:
Can anyone help me how I can resolve this?
Thanks
Hemen

For people who has the same error message:
This could be a configuration error.
Take a look into the WAR file of the EAR which will be deployed. In my case was the WEB-INF folder copied into the CLASSES folder so that he adfc-config.xml was two times in the WAR-File.
WAR-File
¦   home.jspx
¦   ...
¦
+---WEB-INF
    ¦   adfc-config.xml
    ¦   faces-config.xml
    ¦   ...
    ¦
    +---classes
        +---META-INF
        ¦       adfm.xml
        ¦
        +---WEB-INF
                adfc-config.xml
                faces-config.xml
                ...In my case I had edit WAR-Deployment configuration of the ViewContorller projekt properties. There is a tree with a node "WEB-INF/classes", which has a child node "Filters". On the right you see the files which will be deployed. I've unchecked the WEB-INF subfolder and redeployed it.
Now the errors are gone.

Managed Bean Help for Definition Help

I am working on creating Managed Bean Help for Definition Help as described in ‘19.5.3 How to Create Managed Bean Help’ section of the Web User Interface Developer's Guide fpr ADF. Using JDev Version 11.1.2.1.0.
Thought I had all the artifacts assembled but when I run the log message is: <ELHelpProvider> <_getTranslationMap> ELHelpProvider's helpSourceExpression is null.
Any suggestions would be greatly appreciated.
Here is the managed bean:
public class ELHelpProviderProjRequest extends ELHelpProvider {
    public ELHelpProviderProjRequest() {
    /* To use the HelpProvider, the EL expression in the helpTopicId attribute must point to a Map, otherwise
       * you will get a coerceToType error. */
    public Map<String, String> getHelpMap()
          Iterator iterator = _HELP_MAP.entrySet().iterator();
          while(iterator. hasNext()){
          System.out.println("hash map entry " + iterator.next());
        return _HELP_MAP;
    static private final Map<String, String> _HELP_MAP = new HashMap<String, String>();
        static {
          // each element [put] can be for a separate helpTopicId attribute
          _HELP_MAP.put("MAPHELP_CATEGORY_CAPITAL_DEFINITION", "Map value for credit card definition");
          _HELP_MAP.put("MAPHELP_CATEGORY_OTHER_DEFINITION", "Map value for credit card instructions");
} Here is the adf-setting.xml in Application sources / META-INF:
<?xml version="1.0" encoding="windows-1252" ?>
<adf-settings xmlns="http://xmlns.oracle.com/adf/settings" >
<adf-faces-config xmlns="http://xmlns.oracle.com/adf/faces/settings">
<help-provider prefix="MAPHELP_">
    <help-provider-class>
        com.corpnet.abc.util.ELHelpProviderProjRequest
    </help-provider-class>
    <property>
      <property-name>helpSource</property-name>
      <value>#{helpTranslationMap.helpMap}</value>
    </property>
</help-provider>
</adf-faces-config>
</adf-settings>Here is the faces-config:
<managed-bean>
    <managed-bean-name>helpTranslationMap</managed-bean-name>
    <managed-bean-class> com.corpnet.abc.util.ELHelpProviderProjRequest </managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
</managed-bean>Here is the helpTopicId in the inputText component:
<af:inputText value="Test" inlineStyle="font-weight: bold;" id="it31" simple="true" helpTopicId="MAPHELP_CATEGORY_CAPITAL" readOnly="true"/>

Register the managed-bean as a help provider in the adf-settings xml like:
Example 19-9 Registering a Managed Bean as a Help Provider
<adf-settings xmlns="http://xmlns.oracle.com/adf/settings">
<adf-faces-config xmlns="http://xmlns.oracle.com/adf/faces/settings">
<help-provider prefix="MAPHELP_">
<help-provider-class>
oracle.adf.view.rich.help.ELHelpProvider
</help-provider-class>
<property>
<property-name>helpSource</property-name>
<value>#{helpTranslationMap.helpMap}</value>
</property>
</help-provider>
</adf-faces-config>
</adf-settings>

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

I got it also with this code:
package view.managedBeans;
import classification.bean.ClassificationDocument;
import classification.castor.ClassificationLanguage;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.HashMap;

public class ClassificationLanguageList {
private java.util.List<SelectItem> supportedLanguages = new ArrayList();
public ClassificationLanguageList() throws FileNotFoundException,
MarshalException,
ValidationException {
FacesContext ctx = FacesContext.getCurrentInstance();
ValueBinding vb = ctx.getApplication().createValueBinding("#{data.ClassificationDocumentDataControl}");
DCGenericDataControl classificationDocumentDataControl = (DCGenericDataControl)vb.getValue(ctx);
ClassificationDocument classificationDocument = (ClassificationDocument)classificationDocumentDataControl.getDataProvider();
ClassificationLanguage[] classificationLanguage = classificationDocument.getClassification().getClassificationLanguageList().getClassificationLanguage();
for (int counter = 1; counter < classificationLanguage.length; counter++) {
SelectItem language = new SelectItem();
language.setValue(classificationLanguage[counter].getClassificationLanguageCode());
language.setLabel(classificationLanguage[counter].getClassificationLanguageLabel());
supportedLanguages.add(language);
public void setSupportedLanguages(java.util.List<SelectItem> supportedLanguages) {
this.supportedLanguages = supportedLanguages;
public java.util.List<SelectItem> getSupportedLanguages() {
return supportedLanguages;
}

Generate PDF using Managed Bean with custom HTTP headers

Background
Generate a report in various formats (e.g., PDF, delimited, Excel, HTML, etc.) using JDeveloper 11g Release 2 (11.1.2.3.0) upon clicking an af:commandButton. See also the StackOverflow version of this question:
http://stackoverflow.com/q/13654625/59087
Problem
HTTP headers are being sent twice: once by the framework and once by a bean.
Source Code
The source code includes:
- Button Action
- Managed Bean
- Task Flow
Button Action
The button action:
<af:commandButton text="Report" id="submitReport" action="Execute" />
Managed Bean
The Managed Bean is fairly complex. The code to `responseComplete` is getting called, however it does not seem to be called sufficiently early to prevent the application framework from writing the HTTP headers.
HTTP Response Header Override
* Sets the HTTP headers required to indicate to the browser that the
* report is to be downloaded (rather than displayed in the current
* window).
protected void setDownloadHeaders() {
HttpServletResponse response = getServletResponse();
response.setHeader( "Content-Description", getContentDescription() );
response.setHeader( "Content-Disposition", "attachment, filename="
+ getFilename() );
response.setHeader( "Content-Type", getContentType() );
response.setHeader( "Content-Transfer-Encoding",
getContentTransferEncoding() );
Issue Response Complete
The bean indirectly tells the framework that the response is handled (by the bean):
getFacesContext().responseComplete();
Bean Run and Configure
public void run() {
try {
Report report = getReport();
configure(report.getParameters());
report.run();
} catch (Exception e) {
e.printStackTrace();
private void configure(Parameters p) {
p.put(ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put(ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put(ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put(ReportImpl.SYSTEM_REPORT_PATH, "/reports/rwservlet");
p.put(Parameters.PARAM_REPORT_FORMAT, "pdf");
p.put("report_cmdkey", getReportName());
p.put("report_ORACLE_1", getReportDestinationType());
p.put("report_ORACLE_2", getReportDestinationFormat());
Task Flow
The Task Flow calls Execute, which refers to the bean's `run()` method:
entry -> main -> Execute -> ReportBeanRun
Where:
<method-call id="ReportBeanRun">
<description>Executes a report</description>
<display-name>Execute Report</display-name>
<method>#{reportBean.run}</method>
<outcome>
<fixed-outcome>success</fixed-outcome>
</outcome>
</method-call>
The bean is assigned to the `request` scope, with a few managed properties:
<control-flow-rule id="__3">
<from-activity-id>main</from-activity-id>
<control-flow-case id="ExecuteReport">
<from-outcome>Execute</from-outcome>
<to-activity-id>ReportBeanRun</to-activity-id>
</control-flow-case>
</control-flow-rule>
<managed-bean id="ReportBean">
<description>Executes a report</description>
<display-name>ReportBean</display-name>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
The `<fixed-outcome>success</fixed-outcome>` strikes me as incorrect -- I don't want the method call to return to another task.
Restrictions
The report server receives requests from the web server exclusively. The report server URL cannot be used by browsers to download directly, for security reasons.
Error Messages
The error message that is generated:
Duplicate headers received from server
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.Nevertheless, the report is being generated. Preventing the framework from writing the HTTP headers would resolve this issue.
Question
How can you set the HTTP headers in ADF while using a Task Flow to generate a PDF by calling a managed bean?
Ideas
Some additional ideas:
- Override the Page Lifecycle Phase Listener (`ADFPhaseListener` + `PageLifecycle`)
- Develop a custom Servlet on the web server

Thank you!

The problem was that the HTTP headers were in fact being written twice:
1. The report server was returning HTTP response headers.
2. The bean was including its own HTTP response headers (as shown in the question).
3. The bean was copying the entire contents of the report server response, including the headers, into the output stream.
Firefox ignored the duplicate header errors, but Google Chrome did not.

Urgent - can't set managed bean value using a form, getting null

I have a form with a bean -- unbelievably, I can't get the values entered into the form by the user to get stored into the bean. Everything is null... I've looked at a zillion examples, posts and compared etc...yet still can't see what is missing.
Here's part of a trace :
[cc]Dec-31 01:25:02 ApplicationImpl - Created bean resourceBean successfully
[cc]Dec-31 01:25:02 ApplicationImpl - Storing resourceBean in scope request
[cc]Dec-31 01:25:02 VariableResolverImpl - resolveVariable: Resolved variable:id=null name=null
[cc]Dec-31 01:25:02 ValueBindingImpl - getValue Result:id=null name=null
[cc]Dec-31 01:25:02 ValueBindingImpl - -->Returning id=null name=null
If you have any ideas, please let me know--it seems just as I solve one JSF issue, I run into another on unexpectedly simple things.

I solved this.
Since I was testing the action code only, I didn't define a navigation entry corresponding to the action string returned for this button:
<h:commandButton value="Add" style="height:21px; width:51px;font-size:8pt; font-color: black;" action="#{resourceBean.addAction}">
</h:commandButton>After I added a nav definition, it worked. I don't know why at this point. I suspect a key step in the lifecycle was pre-empted...someone else can probably explain why. If I get a chance to research it after I'm done with my project, I'll update this post.
Thanks.

Error calling Method on Managed Bean from another Managed Bean

Hi
(Jdev 11.1.1.2.0)
Help please:
I have a managed bean (page flow scope) which is used by my main page for dynamic region flow navigation:
*public class RegionNavigationBean implements Serializable{*+
private String dynamicTaskFlowId = "/WEB-INF/home-task-flow-definition.xml#home-task-flow-definition";+
*public RegionNavigationBean() {*+
*public TaskFlowId getDynamicTaskFlowId() {*+
return TaskFlowId.parse(dynamicTaskFlowId);+
*public void setDynamicTaskFlowId(String taskFlowId) {*+
this.dynamicTaskFlowId = taskFlowId;+
taskFlowId property on main page def is set to +*${pageFlowScope.regionNavigationBean.dynamicTaskFlowId}*+
In a DB table (i.e. View Object on my model layer) I store a menu ID and a corresponding task_flow_id.
Then I have created an action listener class (RegionNavigationListener - page flow scope) which I link to my menu items on my main page (action listener property on menu item = +*#{pageFlowScope.regionNavigationAction.processAction}*+ )
In this action listener (processAction method), I retrieve the row set from the menu VO and find the record which matches my menu ID which caused the action event, thereby retrieving the task_flow_id which must be navigated to.
I then try to retrieve the instance of the RegionNavigationBean with the following statement: RegionNavigationBean regNav = (RegionNavigationBean)JSFUtils.getManagedBeanValue("regionNavigationBean");+
This seems to work fine, but as soon as I try and use this I get NullPointerException error, e.g.:
regNav.setDynamicTaskFlowId(menusRow.gettaskFlowId());+
or even:
System.out.println("%%% " + regNav.toString());+
This is all quite new to me... any help would be appreciated!
Thanks
Mario

Hi Mario,
I think JSFUtils.getManagedBeanValue(String) has difficult to evaluate the "regionNavigationBean" managed bean.
What JSFUtils.getManagedBeanValue(String) do is important. I remember that "JSF scoped" bean can be found by JSF style find method, such as requestScope, sessionScope, applicationScope. For a managed bean put in these scope, scope prefix is not needed, for example: using #{beanName} to locate a requestScope bean. The #{requestScope} prefix is not needed.
But pageFlowScope is different. If a bean is put in the pageFlowScope, you must use #{pageFlowScope.beanName} to locate it.
Say, ManagedBean is the java class of your manged bean.
FacesContext ctx = FacesContext.getCurrentInstance();
Application app = ctx.getApplication();
ManagedBean mb = (ManagedBean)app.evaluateExpressionGet(ctx, "#{pageFlowScope.managedBeanName}", ManagedBean.class);
Hope it helps.

JSF - Best Practice For Using Managed Bean

I want to discuss what is the best practice for managed bean usage, especially using session scope or request scope to build database driven pages
---- Session Bean ----
- In the book Core Java Server Faces, the author mentioned that most of the cases session bean should be used, unless the processing is passed on to other handler. Since JSF can store the state on client side, i think storing everything in session is not a big memory concern. (can some expert confirm this is true?) Session objects are easy to manage and states can be shared across the pages. It can make programming easy.
In the case of a page binded to a resultset, the bean usually helds a java.util.List object for the result, which is intialized in the constructor by query the database first. However, this approach has a problem: when user navigates to other page and comes back, the data is not refreshed. You can of course solve the problem by issuing query everytime in your getXXX method. But you need to be very careful that you don't bind this XXX property too many times. In the case of querying in getXXX, setXXX is also tricky as you don't have a member to set. You usually don't want to persist the resultset changes in the setXXX as the changes may not be final, in stead, you want to handle in the actionlistener (like a save(actionevent)).
I would glad to see your thought on this.
--- Request Bean ---
request bean is initialized everytime a reuqest is made. It sometimes drove me nuts because JSF seems not to be every consistent in updating model values. Suppose you have a page showing parent-children a list of records from database, and you also allow user to change directly on the children. if I hbind the parent to a bean called #{Parent} and you bind the children to ADF table (value="#{Parent.children}" var="rowValue". If I set Parent as a request scope, the setChildren method is never called when I submit the form. Not sure if this is just for ADF or it is JSF problem. But if you change the bean to session scope, everything works fine.
I believe JSF doesn't update the bindings for all component attributes. It only update the input component value binding. Some one please verify this is true.
In many cases, i found request bean is very hard to work with if there are lots of updates. (I have lots of trouble with update the binding value for rendered attributes).
However, request bean is working fine for read only pages and simple binded forms. It definitely frees up memory quicker than session bean.
----- any comments or opinions are welcome!!! ------

I think it should be either Option 2 or Option 3.
Option 2 would be necessary if the bean data depends on some request parameters.
(Example: Getting customer bean for a particular customer id)
Otherwise Option 3 seems the reasonable approach.
But, I am also pondering on this issue. The above are just my initial thoughts.

How to change MANAGED-BEAN-SCOPE??????

Hi Gurus,
How to change the managed-bean-scope? In my ADF application I have created one backing bean which has attched with the page fragment. I cant able to set the bean scope other than REQUEST....
If I set the bean scope request, then page and the inside fragment is rendering without any error. But I need to make that bean scope to pageFlow... but if I do, getting the below error. Non of the scopes are working except request... Please help me how to set the other scope which will solve my major development issue!!!!

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.

Pageless Managed beans and operation bindings, design question

Hi,
I am using ADF Faces and ADF BC and JDev 10.1.3.
I want to declaratively execute an operation binding from a managed bean which does not have a page definition.
How can I create a page definition for a managed bean which will allow me to define and call operation bindings in the same way that you can in a backing bean?
In the past I have used the binding layer to get references to the AM and then execute the client methods directly.
How can I do this declaratively from a managed bean?
regards,
Brenden

Hi Steve,
a good example would be a managed bean which is used by many pages for provide dynamic page forwarding (using global forwards).
The page forwarding is based on what data the user has selected and the entry tasklist will have pages added and removed based on the users entered information.
At the moment I use references in the managed bean which get the binding context by evaluating #{data} to get a reference to the AM and directly call an client method, which calls a PL/SQL procedure and returns a global forward string. The AM is imported into the managed bean and methods called directly.
This is just one example, but probably the best I can come up with for now.
In a backing bean I can use an operation binding to call a method and get a result declaratively like this:
        BindingContainer bindings = getBindings();
        OperationBinding operation = bindings.getOperationBinding("getUserByEmail");
        operation.getParamsMap().put("email", email);
        String userName = (String)operation.execute();whereas in a managed bean I have to get direct references to the AM to call the method directly.
if there is a way to do this in the same way as backing beans it would seem a more abstracted and cleaner approach?
regards,
Brenden

Identical view but different managed beans?

Hi everyone,
We have a situation where we have jsf code that is identical for 2 different pages, except that the managed bean(backing bean) is different. We are having to duplicate the jsf code just because of this. It would be much easier to maintain if we could share the jsf code between the two beans(and somehow have it use the backing bean that it needs to use at the right time). Is there a way to do this?
Thanks in advance!
-M

This code is part of a component that allows users to input their address(add page). On another page(settings page), where the user sets defaults for the system, the exact same code is needed for them to set their default address.
When the user goes to the add page, this default address is populated, the user can continue using the default or change it.
Hope this makes sense. Thanks.

Managed bean configuration

Hi experts,
In which two places do you configure managed beans?
A. In the page definition file
B. In the faces-config.xml file
C. In the adfc-config.xml file
D. In the Property Inspector
E. In the task flow definition files
Thanks

In the faces-config.xml file
. In the adfc-config.xml file

Error while opening a popup from managed bean

Hi,
I am trying to open a popup from bean, after another popup is closed. When I open the second popup either through ActionListener(on first popup button) or DialogListener(on first popup), I am getting the below error on browser status bar(!); and the second popup doesn't open. There is no error in the log.
*'AdfPage.PAGE.findComponent(...)' is null or not an object.*
Although the popup id is there on the jspx page.
<af:popup id="confirmationStatus" binding="#{MyBean1.confirmationStatus}">
<af:dialog cancelVisible="false"
closeIconVisible="false" binding="#{MyBean1.d2}"
title="Appointment Confirmation Status">
<af:outputText value="Appointment is successfully confirmed"/>
</af:dialog>
</af:popup>
public void confirmAppointment_dialogListener(DialogEvent dialogEvent) {
FacesContext context = FacesContext.getCurrentInstance();
ExtendedRenderKitService service = Service.getRenderKitService(context, ExtendedRenderKitService.class);
String popupId = "confirmationStatus";
service.addScript(context,"AdfPage.PAGE.findComponent('" + popupId + "').show();");
Please tell me why my popup is not getting open from the managed bean and I am getting an error in below line.
service.addScript(context,"AdfPage.PAGE.findComponent('" + popupId + "').show();");

To find out the right address of a component related to an other component, open your page select the component you want to add a partial trigger, go to the partial trigger property, select the down arrow at the right end and select 'Edit'. Now look for the popup in the component tree shown on the left side. When you have found the popup shuffle it the the selected side and click OK. The string you see in the field is the full address of the popup related to he component you've selected. Try the string you see there in your bean code. Remove the string from the partial trigger property, it's just to get the correct path.
One other thing to check is that your popup has the ClientComponent property set to true.
Next thing to try, is to use AdfPage.PAGE.findComponentByAbsoluteId(...)

How to pop up a browser window from a managed bean?

I have a user case like this:
User login our home website. He/she clicks a button. Control flow goes to a managed bean (MB here after) to check some conditions. If conditions are met, instead of sending the user back to the home page, the user will be presented a new web site (e.g. forums.oracle.com) in a popup window on top of our home site.
Can we invoke a website in a adf popup? If so, how to do that? If not, any idea on how to develop this use case?
Any idea is appreciated.

Sorry, I have updated the previous reply with the required inputs.
For convenience, putting it again;
if you need to check for some condition and then invoke the browser, you could use the following code in your managed bean for af:commandButton for Action.
import javax.faces.context.FacesContext;
import org.apache.myfaces.trinidad.render.ExtendedRenderKitService;
import org.apache.myfaces.trinidad.util.Service;
public class TestURLPageBean {
public TestURLPageBean() {
super();
public String onClick() {
*// Check for the condition here and invoke the browser only if it is true*
if (true) {
ExtendedRenderKitService erks =
(ExtendedRenderKitService)Service.getRenderKitService(FacesContext.getCurrentInstance(),
ExtendedRenderKitService.class);
StringBuilder script = new StringBuilder();
script.append("window.open('http://www.google.com');");
erks.addScript(FacesContext.getCurrentInstance(),
script.toString());
return null;
Thanks,
Navaneeth
