  I need to access EJB session bean in JSF managed bean and some methods of execution by program

  Work method and return EJB below
  Is this fair? Another way

  Hi Isabelle,.

  I assumed that his Session EJB bean has not been exposed as a data control (my bad, didn't read any of the discussion).

• Attribute in JSF Managed Bean

  Hi all
  
  I have problem for assignment and to retrieve the value of an attribute in JSF Managed Bean.
  
  Scenario:
  
  public class jsf_managed_bean {}
  
  RichInputText it1.
  RichPopup p1.
  RichDialog d1;
  RichInputText it2.
  Number x;
  
  Methods getter and setter of all attributes
  
  public void setdialog (PopupFetchEvent e) {}
  the handle of the pop-up window
  this.setX (1);
  }
  
  {} public void getdialog (of DialogEvent)
  * if (this.getX () == 1) {*}
  Handle the event dialogue;
  }
  }
  
  }
  
  }
  
  
  When I access the variable in getDialog [DialogListener], I get NULL.

  You can access the instance of the component, because its get auto-câblé with its bean with all support requests incoming. To your string, simply change the methods so something like:

  public String getX()
  {
      return (String)getViewScope().get("x");
  }
  
  public void setX(String x)
  {
      getViewScope().put("x", x);
  }
  
  protected Map getViewScope()
  {
      return AdfFacesContext.getCurrentInstance().getViewScope();
  }
  

  Not too bad isn't?

  Kind regards

  Hello

  You can do this using the FacesMessage class and this can be written anywhere within action/actionlistener/valuechangelistener/post etc...

  Example Code:

  //adding global message, which is displayed with af:messages tag
  FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "Value entered is invalid");
  context.addMessage(null, msg);  
  
  //Component level message, need to use af:message tag. This component level message is also displayed under af:messages tag unless globalOnly property is set to true
  msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, null, "component level message - Value entered is invalid");
  context.addMessage(FacesContext.getCurrentInstance().getViewRoot().findComponent("

• 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']}"/ > "

  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.

• JDeveloper 11 g managed bean &amp; resource bundle mysteries

  Hello
  
  I literally fight JDeveloper to make the location of my application. I want to set the locale of all my pages to a value of a managed bean (which gets the database for all users), so I put < f: view local = "#{Configuration.language}" > and get all the labels and strings in my UI to a resource group.
  
  Two issues were raised:
  
  1. I created a bean managed and recorded as 'Configuration' in faces-config. XML with scope. The managed bean is a private channel 'language' with accessors. When I use the "expression builder" on any page, it creates the following expression: "#{applicationScope.Configuration.language}". Unfortunately, it returns nothing. Manual change of the expression "#{Configuration.language}" finally returns! Why isn't he created like this by the generator expressions in the first place? I did sth. evil?
  
  2. I created a resource 'view.resources.UIresources' group and registered as "res" in faces - config.Xml. reference manually as #{res ['arbpl.titel ']} works fine. When the regional settings of the page are changed, strings are loaded from the appropriate resource bundle. As there is a lot of hits, I would use the wizard 'Select a resource text' or enter the values directly in the designer.
  
  However, the Assistant to "Select a text resource" refers to some crazy #{viewcontrollerBundle ['arbpl.titel']} and add "< c:set var ="viewcontrollerBundle"value="#{adfBundle['view.resources.UIresources']}"/ >" under the jsp:root. What is everything? The problem is that this way always the default resource group appears to be responsible no matter what locale are defined in the f: view.
  
  Who can help me see clear here?
  
  Thank you
  Matt

  Matt,

  Step 1 - really think you so that it is within reach of the session - if it is different for each user, it should be.

  In addition, on the generator, you are using the node called JSF managed Beans and navigate directly on your beans?

  If its scope of the bean to support, then it will be

  #{backingBeanScope.backing_page1.d1}

• Managed bean doesn't have this property error

  Hello

  I want to show the Group of radio buttons on my page. The values I put in my managed bean method that returns a list.

  I took a selected component of radio one and he chose my method that returns a list.

  But when I run the page it gives error that the class does not have the property.

  Here is the code that I wrote in the method which returns the list:

  Please let me know what is the problem here. 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"; +
  
  * public RegionNavigationBean() {* +}
  *}*
  
  * public TaskFlowId getDynamicTaskFlowId() {* +}
  Return TaskFlowId.parse (dynamicTaskFlowId); +
  *}*
  
  * public void setDynamicTaskFlowId (String taskFlowId) {* +}
  this.dynamicTaskFlowId = taskFlowId; +
  *}*
  *}*
  
  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);

• call method before managed Bean support page

  Hi guys,.

  My Version of Jdev is 12 c. I want to call a method of bean managed before my Page load. I did an EnableDisableMethod() method in my managed Bean that is my default activity in my taskflow. This method is only how to turn off to some of my Page buttons. I use * in my control flow so that my page will be called each time after the execution of my method by default. But what my result will be fixed for my activity method. Also what is the use of the result sets.

  <-l' id = 'enableDisable' method call >

  < method > #{pageFlowScope.bgBean.enableDisable} < / method >

  < result >

  < / results >

  < / method >

  Also when I run that application.page is empty but in newspaper that comes

  When I'm debugging its my default front method call load.but page does not redirect to my page. I think that the problem with my key component.before page load it does not know my button

  mainBtnAdd.setDisabled (true);  It is here, I think what he does ' t know button until pageLoad.mainBtnAdd is null in debug mode.

  Thank you

  Raul

  Oh and Yes your button is known that once the page is rendered. To solve your problem you add to the bean (Boolean or string) which then reference you via el of the property of button on the properties page. In method you you set just the properties of the bean.

• Several fragments of the page pointing to the same managed bean

  Hi all

  Jdev version 11.1.1.7.1

  I wanted to know if we can point to several jsff developed o your managed bean?

  While I'm trying to do, I don't get the option to create a new property or use an existing property of the bean while creating a link.

  Is this possible, if so what should be the scope of these beans.

  Hi Ashish,

  The field itself has been disabled for me, what I did was save the bean in the scope of the Session in the config of the adfc. Now its working fine for me.

  It seems that the bean was not found. You set in your config adfc. XML or a btf config? Make sure the names of the bean defined in one of the old config files match. Otherwise, check the exact scope of the bean.

• 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.
