  If you want to reference audio files in your application, the above will not work.  You must code differently.

  try something like this

  Class cl = Class.forName(replace_this_with_your: packageName.classname); //
  InputStream is = cl.getResourceAsStream("/somesound.mp3");
                 
  Create an instance of the reader of the InputStream
  p = Manager.createPlayer (that is, "audio/mp3");

• javax.faces.FacesException: javax.el.PropertyNotFoundException:

  Hi Experts,
  
  I need to hide a panelFormLayOut by program component. My requirement, it is as if I select a specific tab among the tabs on my screen a specific paneFormLayout containing some component of the child should be disabled. To achieve this, I created a bean named "* selectTabBean." In the bean class, I added the getter and setter for the RichPanelTab component. Inside of the same class, I added the method below:
  
  * public boolean disableEnablepanelForm() {*}
  Boolean selectedBooleanValue = false;
  RichPanelTabbed richPanelTabbed = getSelectedTabForEnableformLayOut();
  * for (child UIComponent: richPanelTabbed.getChildren ()) {*}
  RichShowDetailItem sd1 = child (RichShowDetailItem);
  String tabName = sd1.getText ();
  * if ("Manage System".equals (tabName)) {*}
  selectedBooleanValue = true;
  *} else {*}
  selectedBooleanValue = false;
  *}*
  
  *}*
  Return selectedBooleanValue;
  *}*
  
  Now, I registered the bean with my task bounded by the scope of the pageflow. Then for the property of visibility for the panelFormLayOut I added the below expression:
  
  * "#{pageFlowScope.SelectTabBean.disableEnablepanelForm}" *.
  
  Now, when I started running my application, I get the exception below:

  For Boolean values, the method signature is Boolean isDisableEnablepanelForm() and not just "disableEnablepanelForm".
  For normal attributes, you use PositionX and setX, boolean SetB and isB.

• While other that a backup or session scope irritates me javax.el.PropertyNotFoundException exception

  JDeveloper 12.1.3

  Before entering the above error here is what I am doing (explained using schema HR)

  -Let's say I have a page with the table which shows the departments.

  -Just above the table, I have SelectOneChoice LOV with only two values:

                          <af:selectOneChoice label="Resources for" id="soc5555"
                                              valueChangeListener="#{viewScope.mybean.filterChanged}" autoSubmit="true"
                                              value="#{viewScope.mybean.selectedValue}">
                              <f:selectItem id="si555" itemLabel="All Departments" itemValue="All"/>
                              <f:selectItem id="si666" itemLabel="Current Department" itemValue="Current"/>
                          </af:selectOneChoice>
  

  For now ignore viewScope in the code above

  -VO departments has a VC I can put whatever the Department then when the clause is like this:

   ( (Departments.DEPARTMENT_ID = :pDeptId ) ) 
  

  -Department VO also has VOIimpl method setDepartment who gets the int value. If this int value is equal to 0 (zero), I call removeViewCriteria or if other value indicates DepartmentId, I call applyViewCriteria and in both cases, run the query. Let's say I have a global variable which holds DepartmentId. If just before I open this page in a workflow, I invoke method activity (this VO method).

  So far so good. Page and table displays the table with a (current) Department only

  -L' requirement is that when the page opens SelectOneChoice LOV displays "current Ministry". This is because the table will display the current Department loading. I am using the selectedValue property in the bean and set the default value in the Get accessor. (It's probably part of the problem)

  
  

      private String selectedValue;
      public void setSelectedValue(String selectedValue) {
          this.selectedValue = selectedValue;
      }
      public String getSelectedValue() {
          if (selectedValue==null) {
              selectedValue="Current";
          }
          return selectedValue;
      }
  

  -Now when the user changes SelectOneChoice it will call the filterChanged method that calls the method VOImpl of the above. Basically, I want to display either all departments in the table or whatever is the current.

  That is the problem.

  (1) if the bean is supporting the scope of the bean, then whenever I change selectedValue SelectOneChoice will be null which is then set to "Current" in the code above. As a result, filterChanged will not be called when going at all aware in SelectOneChoice because he thinks that the value has not changed :)

  (2) if I put my grain of session scope, I don't have a problem described in point 1) because selectedValue remains stable in memory. But the problem is in this case if the user navigates on the page with all the selected and then revisit the page. Page will load with current Department displayed in the table (due to activity method above) and all in the SelectOneChoice, since this is the memorable session scope variable.

  So I thought to change the scope of the viewScope memory, but I get the above error in the title.

  Issue.

  How to set default SelectOneChoice to the specific hard-coded value when the page opens for the FIRST time?

  OK I solved this problem, it's really simple.

  Everything else is the same.

  If you change the extent of the scope of the request, then, the value should be like

  #{backing_page1.d1}

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

  #{backingBeanScope.backing_page1.d1}

  For the disabled in date property. MinValue, you need to point to a managed bean class that implements the org.apache.myfaces.trinidad.model.DateListProvider interface.

• 11.1.2 bug with iteratorBinding?

  It worked in 11.1.1.5 but in 11.1.2 I get the following error:
  
  javax.el.PropertyNotFoundException: the class 'oracle.jbo.server.ViewRowImpl' has no property 'short name '.
  
  
  
  < af:forEach elements = "#{bindings." Var DictionaryVO1.iteratorBinding.allRowsInRange}"="row">
  < f: selectItem id = 'ds1' itemLabel = "#{row.name}" ItemValueOptional = "#{row.shortName}" / > "
  < / af:forEach >

  Hello

  You should have class RowImpl generated for DictionaryVO1 if you want to access its attributes of the rank else he's trying to get in ViewRowImpl coming obviously getShortName method.

  @Vinod - dataProvider is not supported on ADF BC

• Javax.mail.AuthenticationFailedException error ColdFusion 11: 451 4.7.0

  We are setting up a new server, SEE 11. We receive this error "error javax.mail.AuthenticationFailedException: 451 4.7.0" in newspapers when we use the intrusion via cfmail, who has worked for years on a CF9 server. Mail is also in the undelivered folder. We can slide the coil, but it just comes back.

  We use MS Exchange 2013 and we added our servers CF11 IP address into the connector of the interface we use to relay messages to allow email from our server see

  If something has changed with how ColdFusion processes the e-mail of CF9 to CF11?

  Our current intrusion via cfmail settings.

  < intrusion via cfmail to = "" #theSendTo # ""

  CC = "" #theSendCC # ""

  Server = "mail.xenegrade.net"

  from = "" #theFrom # ""

  username = '< ourDomain\ourUsername > '.

  password = "< ourPassword >".

  object = "" #theSubject # ""

  ReplyTo = "#theFrom #" >

  I am sorry to say that I have this same problem.  We are still running CF10 and have * never * been able to connect to Exchange with intrusion via CFMail since upgrade to CF9, no matter what we tried.  Our solution was to use the file 'mail.jar' of CF9.  Just replace this in your CF installation directory and restart CF.  It works perfectly on our installation CF10.  Sorry, haven't tried on CF11 yet.

  Oh and keep this file mail.jar CF9 on hand, because many of the security updates that you install for CF will restore the original file of the mail.jar.  We simply copy the JAR of CF9.

  Wish I had a better solution for you.
