• Generate PDFS using Managed Bean with custom HTTP headers

  Background
  Generate a report in various formats (PDF, delimited, Excel, HTML, etc.) using JDeveloper 11 g Release 2 (11.1.2.3.0) when you click on an af:commandButton. See also the version StackOverflow about this issue:
  
  http://StackOverflow.com/q/13654625/59087
  
  Problem
  The HTTP headers are sent twice: once by the framework and once by a bean.
  
  Source code
  The source code includes:
  
  -Action button
  -Managed Bean
  -Task flow
  
  Action button
  The action of the button:
  
  < af:commandButton text = 'Report' id = 'submitReport' action = "Execute" / >
  
  Managed bean
  The managed Bean is relatively complex. The code "responseComplete" get called, however, it does not seem to be called early enough to avoid the framework application writes the HTTP headers.
  
  Substitution of HTTP response header
  
  /**
  * Defines the HTTP headers must indicate to the browser that the
  * the report must be downloaded (not 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());
  }
  
  Question answer full
  The bean indirectly says infrastructure that the answer is managed (by the bean):
  
  getFacesContext () .responseComplete ();
  
  Bean, run and configure
  
  public void run() {}
  try {}
  Report = getReport();
  Configures (Report.GetParameters ());
  Report.Run ();
  } catch (Exception e) {}
  e.printStackTrace ();
  }
  }
  
  private void configuration (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());
  }
  
  Workflow
  The workflow calls Execute, which refers to the 'run()' of the bean method:
  
  entry-> Home-> run-> ReportBeanRun
  
  Where:
  
  <-l' call the method id = "ReportBeanRun" >
  < description > running a report < / description >
  Report to run < display name > < / display-name >
  < method > #{reportBean.run} < / method >
  < result >
  success of < fixed-result > < / fixed-results >
  < / results >
  < / method >
  
  The bean is assigned to the scope of the "demand", with a few managed properties:
  
  < rule of flow control = "__3" id >
  hand < of-activity-id > < /-activity-id >
  < control-flow-case id = "ExecuteReport" >
  run < from outcome > < / de-results >
  ReportBeanRun < to-activity-id > < / to-activity-id >
  < / control-flow-case >
  < / control-flow-rule >
  
  < managed-bean id = "ReportBean" >
  < description > running a report < / description >
  < display name > ReportBean < / display-name >
  application of < managed-bean-scope > < / managed-bean-scope >
  ...
  < / managed-bean >
  
  The "success < fixed-result > < / fixed-result > ' strikes me as wrong - I don't want to not the method call to return to another task."
  
  Restrictions
  The report server receives requests from the web server only. The URL of the report server cannot use browsers to download directly, for security reasons.
  
  Error messages
  The error message is generated:
  

  Duplicate received headers from the server
  

  
  349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION) error: multiple headers received separate Content-Disposition. It is not allowed to protect themselves against HTTP response splitting attacks. Nevertheless, the report is generated. Prevents the framework to write headers HTTP would solve this problem.
  
  Question
  How can define you HTTP headers in ADF using a workflow to generate a PDF file by calling a managed bean?
  
  Ideas
  
  Some additional ideas:
  
  -Substitute the listener of the Phase of the lifecycle of Page ("ADFPhaseListener" + "PageLifecycle")
  -Develop a customized web server Servlet

  Thank you!

  The problem was that the HTTP headers have been actually written twice:

  1. the report server returns the HTTP response headers.
  2. the bean was his own (as mentioned in the question) HTTP response headers.
  3. the bean was copy all the contents of the report server response, including headers, to the output stream.

  Firefox has ignored the header in double, but not Google Chrome errors.

• Dynamic class

  With dynamic Classes you can add properties at run time. But the same thing can be done with no dynamic classes by using the prototype property. For example I have a person class whose code is as follows:
  
  Class person {}
  private var: identification number;
  function Person() {}
  ID = 007;
  }
  }
  
  This class is now used in a fla file and create two instances
  
  var xx:Person = new Person()
  var yy:Person = new Person()
  
  trace (XX.__name) //undefined
  trace (yy.__name) //undefined
  
  Person.prototype.__name = "myPersonClass"
  
  trace (XX.__name) //myPersonClass
  trace (yy.__name) //myPersonClass
  
  If this is true then what is the difference between dynamic and not dynamic coz of classes using the prototype property, we can convert each class in the dynamic class.

  with a dynamic class, you can assign distinct __name properties for each instance.

  what you did was to extend the Person class, so it has a new property. If the Person class was final, you wouldn't be able to do. Otherwise, you can.

• Using @Interceptors with ADF managed beans

  Hi Experts,

  I am using the annotation javax.interceptor.Interceptors on my methods of ADF managed beans, but my methods of interception are not get called.

  Is it possible to use it with controlled beans? Has anyone tried this before?

  JDev: 11.1.1.7

  Java: 1.7

  MyInterceptor.java

  =========

  public class MyInterceptor {}

  public MyInterceptor() {}

  Super();

  }

  @AroundInvoke

  public object intercept (InvocationContext context) throws Exception {}

  System.out.println ("MyInterceptor - logging BEFORE calling method:"+ context.getMethod () .getName () ");

  Object result = context.proceed ();

  System.out.println ("MyInterceptor - logging AFTER calling method:"+ context.getMethod () .getName () ");

  return the result;

  }

  }

  =========

  SomeBean.java

  =============

  public class SomeBean {}

  @Interceptors (MyInterceptor.class)

  {} public void doReset (ActionEvent actionEvent)

  do something

  System.out.println ("In reset");

  }

  }

  =============

  Thank you

  Soham

  As far as I KNOW, JSF(and ADF) can't stand the interceptors.

  Maybe you can try this in 12.2.1 jdev because with this version is packaged 2.2 JSF (which should support the CDI)

• How to call a function with parameters in jsf managed Bean

  Hello

  1. I created a Bean managed to manage chains of jsf to 11.1.1.7 WebCenter spaces:

  public class ManageStrings {}

  / * Converts all characters in a string to uppercase. */

  public String getToUpperCase (String str) {}

  Dim retVal = str.toUpperCase ();

  Return retVal;

  }

  }

  2. I registered managed Bean:

  " < managed-bean id ="swc_3"xmlns =" http://xmlns.Oracle.com/ADF/controller "> "

  < id managed-bean-name = "swc_2" > tools < / managed-bean-name >

  < managed-bean-class id = "swc_1" > cat.badalona.webcenter.utilities.ManageStrings < / managed-bean-class >

  < managed-bean-scope id = "swc_4" > backingBean < / managed-bean-scope >

  < / managed-bean >

  3 to code jsf, I tried different options, but they do not work

  " < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value="#{backingBeanScope.utilities.getToUpperCase['hello']}"/ > "

  ...

  " < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value="#{backingBeanScope.utilities.toUpperCase['hello']}"/ > "

  ..

  " < = xmlns:af af:outputText ' http://xmlns.Oracle.com/ADF/faces/rich "value =" #{backingBeanScope.utilities.getToUpperCase ('hello')} "" / >

  
  

  What I am doing wrong?

  
  

  Thaks in advance
  

  
  

  Hello Carles,

  I did it with the content presenter where I need to pass the ID of the component selected in backing bean. Please try below option

  Now add following code in your binding

  Private RichOutputText outputText1;

  then the getter for this outputtext set.

  and in your action method to read the value of the output text.

  Hope this helps with your problem.

  Thank you

  I tried setting the scope of control of data in the workflow for the popup shared and isolated, the behavior is the same.  I thought that the scope must be insulated for the tf of the pop-up window.  The data-control-scope on the calling workflow shared.

  No idea why?

  Thanks - Rudy

  I don't know if you can disable registration points. However, I'd go for the second option to bind components to ask the beans reach max.

  This way you don't have problems later and it is best practice not to tie UI components to the higher bean then ask. You can adopt the UIManager (https://blogs.oracle.com/groundside/entry/the_uimanager_pattern) model.

  Or use ComponentReference as shown here https://blogs.oracle.com/ATEAM_WEBCENTER/entry/rules_and_best_practices_for

• AS3 - Dynamic class names with * new * operator

  I use AcrtionScript 3 and Adobe Flash 9 Public Alpha.
  
  I have 50 clips in the library that use the binding to set the class name: Img1, Img2, Img3,..., Img50.
  I have a parent named RandImg class. I want the constructor of RandImg select one of the 50 film clips from the library randomly and display it. I could get this to work by generating a random number and then writes a statement to switch really huge to associate each random number to its name of library Movie Clip respective class, but I'd rather do it with a name of variable dynamic/class based on the random number, such as:
  
  var nImgChoice:Number = Math.floor (Math.random () * 50) + 1;
  var mcImg:MovieClip = new ["Img" + String (nImgChoice)] (of).
  addChild (mcImg);
  
  Note that this has been possible in AS 2 as follows:
  
  this.attachMovie ("Img" + String (nImgChoice), "mcImg", this.getNextHighestDepth ());
  
  Suggestions?
  Thank you

• The flow of work, Servlet, popup and a managed Bean validation

  Hello
  
  We try to display a PDF file in a pop-up window by calling a Servlet in a JSF page using a workflow in JDeveloper 11 g R2.
  
  The relevant part of JSF:
  

  <af:inlineFrame id="if1" shortDesc="Report" source="/pdfservlet" styleClass="AFStretchWidth"></af:inlineFrame>

  The /pdfservlet points to a Servlet with a method doGet as follows:
  

  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.reset();
    
    OutputStream out = response.getOutputStream();
  
    FacesContext context = this.getFacesContext(request, response);
    OracleReportBean bean =
      context.getApplication().evaluateExpressionGet(context, "#{reportBean}", OracleReportBean.class);
  
    bean.run(context, out);
    removeFacesContext();
  
    out.close();
  }

  The Servlet is trying to get the FacesContext, but we met with the following exception:
  

  Caused By: javax.faces.FacesException: Cant instantiate class: oracle.adfinternal.view.faces.component.AdfViewRoot.

  We have removed the following lines to the getFacesContext() method:
  

  UIViewRoot view = facesContext.getApplication().getViewHandler().createView(facesContext, "");
  facesContext.setViewRoot(view);

  This avoids the exception above, however... We try to get the settings of the form that was submitted. Here is an example of the form element:
  

  <h:inputHidden value="MyMedicationList_Report" id="system_REPORT_RESOURCE"/>

  When the Servlet calls the Bean managed to retrieve the value, it uses:
  

  Map<String, String[]> requestParameters = getRequestParameters();
  Parameters p = getParameters();
  
  for( String key : requestParameters.keySet() ) {
    for( String value : requestParameters.get( key ) ) {
      int i = key.indexOf( ':' );
  
      if( i >= 0 ) {
        key = key.substring( i + 1 );
      }
  
      p.put( key, value );
    }
  }

  Where getRequestParameters() tries to get the external context to retrieve the map of query parameter values:
  

  return getExternalContext().getRequestParameterValuesMap();

  The card is empty.
  
  I tried after http://www.oracle.com/technetwork/developer-tools/adf/learnmore/oct2010-otn-harvest-183714.pdf by assigning the web.xml file:
  

    <!-- JspFilter must be configured before adfBindings. -->
    <filter-mapping>
      <filter-name>JpsFilter</filter-name>
      <servlet-name>PDFServlet</servlet-name>
      <dispatcher>FORWARD</dispatcher>
      <dispatcher>INCLUDE</dispatcher>
      <dispatcher>REQUEST</dispatcher>
    </filter-mapping>
    <filter-mapping>
      <filter-name>adfBindings</filter-name>
      <servlet-name>PDFServlet</servlet-name>
      <dispatcher>FORWARD</dispatcher>
      <dispatcher>REQUEST</dispatcher>
    </filter-mapping>

  And set the data bindings on:
  

    <pageMap>
      <page path="/pdfservlet" usageId="ca_bcpra_promis_reporting_view_PDFServletPageDef"/>
    </pageMap>
    <pageDefinitionUsages>
      <page id="ca_bcpra_promis_reporting_view_PDFServletPageDef" path="ca.bcpra.promis.reporting.view.PDFServletPageDef"/>
    </pageDefinitionUsages>

  The Servlet is running, called the managed bean instantiated, but cannot read the query parameters.
  
  Is the button used to start the workflow in a dialog box:
  

  <af:commandButton text="Run Report" id="submitReport" useWindow="true"
                    windowEmbedStyle="inlineDocument" windowModalityType="applicationModal" windowHeight="500"
                    windowWidth="700" action="runReport"/>

  By using a workflow, the user input are validated before the opening of the pop-up window. We want to keep this behavior. The PDF file opens and then returned with a NullPointerException:
  
  http://pastebin.com/raw.php?i=PaM64jL4
  
  The Servlet, through the managed bean, made a request to the report server to pass parameters and generate a PDF file. The PDF is sent to the browser via the Servlet.
  
  What other steps can we take to:
  
  1. send user and system parameters.
  2. generate a PDF file on a remote server.
  3 distribute the PDF file to the user in a pop-up window.
  
  Thank you.

• Error by calling the method on Bean managed from an other managed Bean

  Hello
  
  (Jdev 11.1.1.2.0)
  
  Help please:
  
  I have a managed bean (page scope of stream) that is used by my homepage for navigation of flow dynamic region:
  
  * / public class RegionNavigationBean implements Serializable {* +}
  private String dynamicTaskFlowId = "/ WEB-INF/home-task-flow-definition.xml#home-task-flow-definition"; +

  taskFlowId is set to the homepage def to + * ${pageFlowScope.regionNavigationBean.dynamicTaskFlowId} * +.
  
  In a table (i.e. display on my model layer object) DB I store a menu ID and a corresponding task_flow_id.
  
  Then I created a class of earphone action (RegionNavigationListener - scope of stream page) which I link to my menu on my main page items (property listener action on the item of menu = + * #{pageFlowScope.regionNavigationAction.processAction} * +)
  
  In this action (processAction method) listening port, I retrieve rowset in the VO menu and find the record that matches my menu ID that triggered the action event, recovering the task_flow_id that needs to be accessed.
  
  I then try to retrieve the instance of the RegionNavigationBean with the following statement: RegionNavigationBean regNav = (RegionNavigationBean) JSFUtils.getManagedBeanValue ("regionNavigationBean"); +.
  It seems to work fine, but as soon as I try to use it I get a NullPointerException error, for example:
  regNav.setDynamicTaskFlowId (menusRow.gettaskFlowId ()); +
  or:
  System.out.println ("%" + regNav.toString ()); +
  
  This is quite new to me... any help would be appreciated!

  Hi Mario,.

  I tried following codes to get a bean managed in a region, it is very good for me.
  ManagedBean is the name of the class.

  FacesContext ctx = FacesContext.getCurrentInstance ();
  Application app = ctx.getApplication ();
  ManagedBean MB = (ManagedBean) app.evaluateExpressionGet (ctx, "#{pageFlowScope.managedBeanName}", ManagedBean.class);

• Please HELP * problem with dynamic regions ADF...

  Hello
  
  I have 2 separate workflow in my application. 'Search-user-flow' & 'create-user-flow. I got to view these feeds in my main application (home) as a dynamic region with 2 dynamic links.
  
  My page main split into two panels where I suppose to display dynamic links on the left side and the workflow right. Want to display the default search feeds loading the home page, and when I click on the link for the user to create, create flow must be exposed to the right side. Please help me how to do the same. I was halfway through the path, but not totally.
  
  Here's what I've done so far.
  
  Step 1) creation research-user-flow (this stream were only page fragments not pages)
  Step 2) created create-user-flow (this stream were only page fragments not pages)
  Step 3) slide / move the search-user-flow in right panel of the main page as dynamic and created new "searchFlow" managed bean and the same card.
  -(After this stage, the main research stream fragment appears in my main page)
  -(Managed bean created taskID entry and the method)
  
  Step 4) slide / move the create-user-flow to the left side panel as dynamic link.
  Step 5) slide / move in the research-user-flow for left side panel as dynamic link.
  
  During the loading of my main page, I could see 2 dynamic links in the Panel left side and 1 flow to the right side panel. Now when I click on the Create User link, it's pass the stream and display the stream of the 2nd on the right. So far so good. Now, if I hit any link here after an error. Please help me how to solve this problem and make the works of dynamic region. It is really urgent and fight with past 4 days...

• Train does not not as expected with dynamic regions

  JDeveloper version - 11.1.1.7.0

  I created an application with 2 workflow with 3 defined fragments like a train. These workflows is deleted a page like dynamic regions. On the page running, in the first region the train works fine. But access to the second region, when I click on the 2nd train stop, the train navigates to the first fragment of the first step.

  Note: I also created a test application, it was the replication.

  I looked at your code and found the problem. The bean that you can switch regions is defined in the scope of evil. The TrainDynamicBean must be set in viewScope at least. If you set it in a scope less (backingBean or application) the bean is generated for each request. If you go to region 2 the bean is created again for the next request, and the taskflowid points again to flow available1. This is the reason why you see the view4 when you switch to flow2 but view5 clicking on flow available1.

  It is a problem.when known and documented, working with dynamic regions. JDev creates the bean in the wrong scope, and you have to take it at least viewScope.

• TableView with dynamic and updatable columns

  Hello!!

  Im trying to encode a TableView with dynamic columns and I saw a lot of examples like this: create columns dynamically

  But none who would work for my needs.

  Its very simple:

  I got a list of customers, and each has a list of purchases.

  A purchase has a string "buyDetail" and a Date for the ship.

  My TableView need the first column with the name of the client, and a column more for each day of existing ships.

  We do not know previously days that will be used.

  If the sum is greater than 100, for example, I need to be able to apply different styles.

  Example:

  Customer	02/01/2015	03/01/2015	09/01/2015
  Morgan	$400 (buyDetail)	0	$100
  Luis	0	0	$20
  Steven	$10	0	0
  Hulk	0	$5	$32

  I can't use the properties because I don't know how to buy will have to each customer.

  My best test (only for the first column) was next, but I can't buy it updated if I change the value in the cell:

  I did not try to write other code columns because I feel that I don't hurt really...

  This shows the names of Customer´s, but I can't manage if data modification.

  table = new TableView<Customer>();
  ObservableList<Customer> lista = FXCollections.observableList(registros);
  
  table.setItems(lista);
  
  TableColumn<Customer, Customer> customerNameColumn = new TableColumn<Customer, Customer>("");
    customerNameColumn.setCellValueFactory(new Callback<CellDataFeatures<Customer, Customer>, ObservableValue<Customer>>() {
    public ObservableValue<Customer> call(CellDataFeatures<Customer, Customer> p) {
    return new SimpleObjectProperty(p.getValue());
    }
    });
  
    customerNameColumn.setCellFactory(column -> {return new TableCell<Customer, Customer>() {
    @Override
    protected void updateItem(Customer item, boolean empty) {
    super.updateItem(item, empty);
  
    if (item == null || empty) {
    } else {
    setText(item.getName());
    //APPLY STYLE
    }
    }
    };
    });
  
    table.getColumns().addAll(customerNameColumn);
  

  Post edited by: user13425433

  The columns are available already update default... If you happen to use JavaFX properties for the value of the source.

  The core of you're your question lies in your cellValueFactory.

  Here we have only the cellValueFactory for the name, not for the other columns. So I'll take the name for example, and you have to adapt to the other columns.

  But if you do something like this to your cellValueFactory:

  new SimpleObjectProperty(p.getValue().getName());
  

  Then the name can never be updated if it modifies the client instance: there is no "link" between the name and the property used by the table.

  We have therefore 3 test case:

  • If the name is a property of JavaFX and you do something like:

  TableColumn customerNameColumn = new TableColumn("Customer");
  customerNameColumn .setCellValueFactory(new PropertyValueFactory<>("name"));
  

  Then, if the name change pending Customer-> value in the table automatically changes.

  It also works the other way around: If the table is editable, and the name property is not unalterable-> the value of the changes of names in the Customer instance follows the table has been changed.

  • Now, if your name is not a property of JavaFX but a Java Bean observable property instead (this means that you can register and unregister an instance of Java Bean PropertyChangeListener to this property), you can do:

  TableColumn customerNameColumn = new TableColumn("Customer");
  customerNameColumn.setCellValueFactory(new Callback, ObservableValue>() {
      @Override
      public ObservableValue call(TableColumn.CellDataFeatures p) {
          final Customer t = p.getValue();
          try {
              return JavaBeanStringPropertyBuilder.create().bean(t).name("name").build();
          } catch (NoSuchMethodException ex) {
              // Log that.
              return null;
          }
      }
  });
  

  In this way, you have created a JavaFX property that is bound to an observable property Java Bean.

  Same as above, it works both ways when possible.

  • The latter case is that your name is neither a JavaFX property or a Java Bean-> you can not update unless you happen to create a kind of observer/listener that can update the property with the most recent value.

  Something like that:

  TableColumn customerNameColumn = new TableColumn("Customer");
  customerNameColumn.setCellValueFactory(new Callback ObservableValue>() {
    public ObservableValue call(CellDataFeatures p) {
      final Customer t = p.getValue();
      final SimpleStringProperty result = new SimpleStringProperty ();
      result.setvalue(t.getName());
      t.addNameChangeListener(new NameChangeListener() {
        @Override
        public void nameChanged() {
          result.setvalue(t.getName());
        }
      });
      return result;
    }
  });
  

  If you don't do something like that, the value of the table will never change when the name changes in the instance because the table does not change.

  Now, you will need to apply this theory to your price columns. I hope that I was clear enough to help you.

• ADF - components of the access to the contents of a managed bean in a HA environment ViewScope.

  Hi all

  I have a question, I am a beginner with ADF and learn a lot through these forums and Google

  Using Jdeveloper 11.1.1.7

  is the question I have, I have a cluster/HA environment (2 knots) and move my application to use HA.

  I changed the ADF - config.xml to add the following line:

  " < adf-controller-config xmlns =" http://xmlns.Oracle.com/ADF/controller/config "> "

  < adf-scope-ha-support > true < / adf-scope-ha-support >

  < / adf-controller-config >

  I currently have a managed bean (ViewScope) and it has all my actionListeners/valueChange etc... etc... It also has my UIComponent links and I have also several methods that define specific attributes on these components and then do:

  AdfFacesContext.getCurrentInstance () .addPartialTarget ("ComponentRefHere");

  I am aware that I have to put my beans managed to implement Serializable I also understand that the UI components are not serializable.

  I use the ComponentReference method that is to say:

      private ComponentReference<RichPanelBox> iframePB;
  
      public void setIframePB(RichPanelBox component) {
          iframePB = ComponentReference.newUIComponentReference(component);
      }
    
      public RichPanelBox getIframePB() {
          return uiComponentBean.getIframePB();
      }
  

  is the question I have, I can leave it like that? or will I move them to a different managed bean?

  If so, how should I put the bean, it must also implement serializable, and how do I access them from my managed bean viewScope.

  
  Thank you

  You don't have to. Https://docs.oracle.com/javaee/6/tutorial/doc/gjbbk.html documentation

  The beans that use the scope of the conversation, application, or session must be serializable, but beans that use the scope of the request need not be serializable.

  I personally always add the serializable interface as the bean has never should be selected for serialization, it should not control. It is easier to tell everyone to add it anyway. In this way, you can use the same class in all scopes.

• character of JSF managed bean error encoding page

  My request is internationalized, and then I need special characters (accents of Spanish, copyright symbol,...). I test if I get the string to a managed bean that does not work.

  JSF page:

  <?xml version='1.0' encoding='UTF-8'?>
  <!DOCTYPE html>
  <f:view xmlns:f="http://java.sun.com/jsf/core" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
      <af:document title="Test" id="d1">        
          <af:form id="f1">        
            <af:panelGroupLayout id="pgl1">
              <af:outputText id="ot1" value="áéióúñ © it works" />
              <af:outputText id="ot2" value="#{myBean.text} it doesn't work" />
            </af:panelGroupLayout>
          </af:form>
      </af:document>
  </f:view>
  

  Bean

  public Class MyBean {
  
  
    public MyBean() {
    }
    
    public String getText(){
      return "áéióúñ ©";
    }
  
  
  }
  

  I found this old post:

  UTF-8 problem with ADF

  But this solution is for the JSPX pages:

  < jsp:directive.page contentType = text/html"; Charset = UTF - 8 "/ >

  How can I solve this problem for ADF 12 c + JSF pages / Fragments of JSF Page. ?

  It should work.

  Check the compiler settings in the project properties (and also check: Tools-> preferences...-> environment)

  Also check the encoding in the file pageDef (if you have one).
