• 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

• Difference between the managed bean scopes.

  Hello.

  I have jdeveloper 11g and I wanted to know what is the difference between the scopes when managed beans (FlowScope, request, Backed Bean, etc.).

  Kind regards.

• 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.

  UTF-8 problem with ADF

  But this solution is for the JSPX pages:

  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).

• [ADF, JDev12.1.3] How to set a variable to bind a VO (where clause) in a managed bean?

  Hallo,

  I have a request based on VO.

  The query contains a where clause clause and a bindi variable.

  In a managed bean I would like to access the iterator of VO setting the value of the bind variable and read the result.

  I found this code it is good start, but I do not know how to set the variable binding.

  BindingContext bctx = BindingContext.getCurrent();
  BindingContainer bindings = bctx.getCurrentBindingsEntry();
  DCIteratorBinding iter = (DCIteratorBinding ) bindings.get("MyVO1Iterator");
  iter.execute();
  
  
  

  You kindly help me?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Sorry if these questions may seem artificial, but I am a beginner, I have many doubts and so I would be happy to receive some tips regarding best practices.

  Thank you

  Federico

  You can use:

  iter.getViewObject().setNamedWhereClauseParam("yourBindVar", value);
  

  Note that this approach is used if you have bind variable in the where clause.

  To set variables bind to ViewCriteria, you must use VarableValueManager.

  This post may be useful for you: binary: how to set the Bind variable values at run time?

  Also, I would like to know if it is generally advisable to use VO directly in controlled beans or whether it would be best to create in the AppModuleImpl methods that do this and return the result.

  You must set "use VO directly.

  For example, from the point of architecture, is probably best to use the method in the model project which will set the bind variable and execute the query.

  Or you can use the ExecuteWithParams operation in your the view layer.

  In my case for example of the VO will return max 1 plug so I'm in doubt, if the creation of a method in the AM that returns a custom class, which attributes contain values of the line of VO.

  Not to complicate your life

  All VO lines are represented as ViewRowImpl class if you already have "custom class".

  Finally, you can generate your own ViewRowImpl class if it is necessary for this.

  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.

  How to use the trigger in the doDML?

  You cannot use db trigger, but you can implement the logic of your trigger, something like:

  protected void doDML(int operation, TransactionEvent e) {
  if(operation==DML_INSERT)
    BigDecimal yourSeq = new SequenceImpl("Learner_seq",getDBTransaction()).getSequenceNumber();
    java.util.Date  sysdate = new java.util.Date();
    SimpleDateFormat  sdf = new SimpleDateFormat("yyyyMM");
    String yourStudentNo = sdf.format(sysdate) + yourSeq.toString();
  
    this.setStudentno(yourStudentNo);
  }
  
  super.doDML(operation, e);
  }
  

  And in your bean you can retrieve the value of the current row.

  One of your previous answers, something like:

  AttributeBinding attrStudentno = (AttributeBinding) bindings.getControlBinding ("Studentno");
  String studentNo = (String) attrStudentno.getInputValue ();

• 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 >

  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.

• 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

  public list choiceList() {}

  System.out.println ("inside the bean');

  DCBindingContainer links =

  (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DCIteratorBinding iter =

  bindings.findIteratorBinding ("TblSurveyQuestionsView1Iterator");

  ViewObject vo = iter.getViewObject ();

  String rowAnswer =

  vo.getCurrentRow ().getAttribute("RowAnswerChoice").toString ();

  ("String [] answers = rowAnswer.split("\\n ");

  System.out.println (response [0] + "navneet" + answers [1]);

  The list of answersList = Arrays.asList (answers);

  Return answersList;

  Rename the method to be getChoiceList() and write another one, with the name setChoiceList(List value) {...}
