• To access the methods of the VORowImpl class

  Scenario is,

  I have a view object class VOImpl.java in the model.view package.

  I have another class of JavaBean EntryHandle.java

  EntryHandle class I can Import model.view.VOImpl;

  Help me now how I can access methods of the VOImpl class in the ADF.

  Or I have to create the VOImpl object class in class EntryHandle? as in programming java Simple? or something else

  JDeveloper Version: 11g Release 2 11.1.2.0.0

  Zaid,

  If you have a VO with 2 attributes, you have defined the category value. (This poster Lov sense and sets the value for the category field).

  You want to get the value selected from the lov. Is this correct?

  When do you get this value? When they choose a new value from the LOV.

  If you have written the code in the valueChangeListener, you can check the link below:

  https://blogs.Oracle.com/ADF/entry/getting_selected_value_from_selectonechoice

  Code of the blog

  public void valueChanged(ValueChangeEvent valueChangeEvent) {
      this.setValueToEL("#{bindings.Deptno.inputValue}", valueChangeEvent.getNewValue()); //Updates the model
      System.out.println("\n******** Selected Value: "+resolveExpression("#{bindings.Deptno.attributeValue}"));
      System.out.println("\n******** Display Value: "+resolveExpression("#{bindings.Deptno.selectedValue ne ' ' ? bindings.Deptno.selectedValue.attributeValues[1] : ''}"));
  }
  
  public Object resolveExpression(String el) {
      FacesContext facesContext = FacesContext.getCurrentInstance();
      ELContext elContext = facesContext.getELContext();
      ExpressionFactory expressionFactory =  facesContext.getApplication().getExpressionFactory();
      ValueExpression valueExp = expressionFactory.createValueExpression(elContext,el,Object.class);
      return valueExp.getValue(elContext);
  }
  
  public void setValueToEL(String el, Object val) {
      FacesContext facesContext = FacesContext.getCurrentInstance();
      ELContext elContext = facesContext.getELContext();
      ExpressionFactory expressionFactory =   facesContext.getApplication().getExpressionFactory();
      ValueExpression exp = expressionFactory.createValueExpression(elContext, el, Object.class);
      exp.setValue(elContext, val);
  }
  

  You can get the selected value and the value of display with the above code. You need to replace Deptno by category.

  See you soon

• What is the method of the String class's trim() in special cases?

  You are looking for here ( String (Java Platform SE 7) ), I understand that the method of the String class's trim() 'returns a copy of the string with white spaces of early and omitted end', but I don't understand what the last special case Unicode characters is exactly.

  You are looking for here ( list of characters Unicode - Wikipedia, the free encyclopedia ), I see that U + 0020 is a space character, and I also see the characters that follow the character space (for example, the exclamation point character).

  So, I decided to write a sample of the size of the code to try to reproduce the behavior that I quoted (from the documentation of the API of the trim method) in the comment from several line of this code even example. Here is the code example. :

  public class TrimTester {
  
      public static void main(String[] args) {
         
          /*
           * "Otherwise, let k be the index of the first character in the string whose code
           * is greater than '\u0020', and let m be the index of the last character in the
           * string whose code is greater than '\u0020'. A new String object is created,
           * representing the substring of this string that begins with the character at
           * index k and ends with the character at index m-that is, the result of
           * this.substring(k, m+1)."
           */
          String str = "aa!Hello$bb";
          System.out.println(str.trim());
      }
  }
  

  However, what is printed is "aa." «Hello bb$ "(without the quotes) instead of «!» "Hello$" (without the quotes).

  Any input to help me better understand what's happening would be greatly appreciated!

  Hallo,

  I think that the characters 'a' and 'b' both have greater than '\u0020' code, so your entire string is returned by the trim () - method, then the first character of the string whose code is superior to ' \u0020 has index 0, and the last character whose code is greater than '\u0020' a index 10. All printable characters have codes greater than 0020, try "\r\ntest". After trim(), you get 'test '.

• Impossible to replace "initialize" method on the Application class

  Returns an error:

  The compiler bug?

  I think the ActionScript class generated by the compiler to your MXML file has its own surrogate autogenerated initialize(). You can check it using the - keep option. I do remember not what does the initialize() generated automatically, but - keep will show you.

  Assuming I'm right, I agree that it is a bad thing for the compiler to, so you should file a bug.

• you have makeContextMenu() method in the field class?

  Hi all
  I use the BlackBerry Plugin on Eclipse.
  I have installed BlackBerry by JRE 5.0.0 project.

  I used the class field on my program. But I can't use certain methods in this class, for example makeContextMenu() method.

  I try to develop 5.0.0 JRE packages on the left side of the window of the Eclipse and I found the net.rim.device.api.ui.Field class. I see all the methods in this class, but there is a method is "YELLOW" and these methods cannot use in my program.

  Can you help me to solve this problem, thanks a lot!

  You must override the method, do not call it directly.  You can see an example of its use in the example here:

• reading viewScope variable in the method of the ViewImpl class

  Hello
  
  Suppose I want to get viewScope.deptno in my function that is declared in the class ViewImpl
  
  ' Public Sub proc (String deptno, String amount) {}
  setp_deptno (deptno == null? ('%': deptno);
  this.setNamedWhereClauseParam ("p_deptno", deptno);
  this.executeQuery ();
  System.out.println("viewScope.DEPTNO="...?);
  }
  
  How to get to it in my service?

  do you mean placing the logics from VOImpl to client interface class?
  

  Yes, then you can see the method exposed in the control of data under the node ViewObject. Then, you can run the method in your method of beans as below

      public String executeMyVOMethod {
          BindingContainer bindings = getBindings();
          OperationBinding operationBinding = bindings.getOperationBinding("proc");
          operationBinding.getParamsMap().put("deptno", PassAnyDeptNo);//you can get it from view scop variable
          operationBinding.getParamsMap().put("amount", passAnyAmmountvalue);  //you can get it from view scop variable
          Object result = operationBinding.execute();
          if (!operationBinding.getErrors().isEmpty()) {
              return null;
          }
          return null;
      }
  

  could you clarify why this is a bad practice to store the logic in VOImpl?
  is it because I can't refer to ViewScope of there?
  >

  access a range of memory variable in your model layer (if its there) is a bad practice, because you're breaking MVC model. This is not the best approach, even if you can do it.

• Import excel should allow space in a column during the use of media: the value class coldfusion.sql.QueryColumn can not be converted to a date

  Odd. Then there can be only one solution to the riddle: what you read is a column name, and not the date value stored in the column.

• How to use methods within the itemRenderer

  Hello
  
  I have basic itemRenderer as a component:
  
  < mx:Component id = "ColorRenderer" >
  < mx:Label
  Text = "{rgb2hex (255,100,50)} ' / / this gives error: 1180: call to a method may be undefined rgb2hex"
  / >
  < / mx:Component >
  
  My method works if I use it with a 'normal' tag < mx:Label = "22" x = "12" text = "{rgb2hex (255,100,50)}" width = "150" / > "
  but it does not work inside the itemRenderer?
  
  What I'm missing here?
  

  When you use the tag you define a new variable scope. In this context, the rgb2hex does not exist. You need to qualify: { outerDocument.rgb2hex (255,100,50)}

• The material inconsistency: getNext() method of the Cursor class

  Hi, I'm a newcomer to Berkeley DB I.
  
  I found an inconsistency between the JavaDoc and the documents of GettingStartedGuide (GSG)
  -the description of getNext().
  
  In JavaDoc, getNext() of a cursor returns first element of data in all of the duplicates if the
  corresponding key has values duplicated, while in GSG, getNext() of a cursor indicates the next record
  in the database, regardless of whether it is a duplicate of the current record.
  
  Maybe I didn't understand what that two descriptions really mean@~ @.
  
  Can anyone help clarify this inconsistency?
  
  Thank you.

  Hello

  Sorry - the javadoc for getNext is incorrect. If you remove this sentence: 'If the corresponding key is duplicated values, the first element of data in all of the duplicates is returned.', then the rest of the javadoc description is correct.

• The session class method "connect."

  Hi all
  
  Anyone know how the argument 'version' in the Connect method of the Session class becomes the PeopleTools version when connecting? I see in the PeopleSoft documentation, it is still defined as "1". However, how he took over the version of PeopleTools of the used psjoa.jar file? Any suggestions?
  
  Session.Connect (version, {'EXISTING' | //PSoftApplicationServer:JoltPort}, user name, password, ExtAuth)
  
  Here's what I'm trying to accomplish:
  
  The below error raises the following when the PS tools connect with does not match what is on the application server. I like to know where to find the version number of PeopleTools on the web server, in the example below, it would be '8.51.16 '. Where is it stored? Is there a way I can call to retrieve this info?
  
  Error:
  
  Release of PeopleTools (8.51.16) for the web server "is not the same as the Application Server PeopleTools release (8.51.08). Access denied. ;
  
  Thank you in advance!
  
  Thone

  So after having read the two messages, I think that the solution of the other post corresponds to your need. Integrate you with PeopleSoft, the client gives you a copy of the psjoa.jar to deploy on your end. It is supposed to match their current version. You probably had problems where they sent you the wrong copy or you have deployed the wrong version somehow, and you want a way to validate the version against what they are running. When you refer to the version on the web server, you really mean the file psjoa.jar on deployed on your server. In which case, I gave you 2 solutions on the other thread.

  If I got that wrong let me know and if not I think we can let this thread go now.

  BTW: If you find my posts useful or answer your question, please report them accordingly. I'm trying to get out of the status of beginner and half of the people asking question never give points :)

  Thank you

• How do I do to make the manager class to run the drawFocus method?

  Hello world.

  Please let me question.

  I want to have the handler class to do drawFocus.

  Development is not won if "FOCUSABLE" is specified to the constructor for the handler class. You know the method of the handler class drawFocus method?

  Moreover, I want to express a given from the list of mail in the handler class.

  JDE 4.6.0 component package

  I solved for oneself.

  The following figure is a thing I wanted to do.

  http://picasaweb.Google.co.jp/LH/photo/9wNNUNZam8MKyV9h1FTquw?feat=DirectLink >

  (Because the image was not displayed by the preview, the link was introduced. "I'm sorry.)

  First of all, I've arranged it at the head of the 'FOCUSABLE' NullField handler class. (The handler class can judge the acquisition of the development of this event.)

  The handler class has a class variable that shows the status of the presence of development.

  And "focusChanged' FocusChangeListener method is mounted.

  The handler class to draw the rectangle in the method object referring to the value of the variable in class to come.

  I want to do there.

  I want to close this question hereby.

  Thank you to save expensive time, Mark.

• With the help of the child in the executable class

  I'm kinda stuck and don't know how to solve and could not find a solution online.

  I have a parent class and its children to the class. The child class only overrides a method, but not the run method. I want to compile the executable project, where the run method is called, but the class type is the child, not parent. How to do this?

  I tried three things, but all in vain:

  (1) in the build properties when I select start VI the run method of the parent, I get in the executable the parent, not the child's class class. It's logical. However, I couldn't find the option to use the child as a type's class.

  (2) when I add the run method of the child class and appeal to parents, I get two windows pop up. The run of the parent and the child method. Too many. Even if for the class child run method (see below the block diagram of a child, red run method's parent), I put not to show the façade when it is called in the properties of VI.

  

  (3) when I tried with a separate VI calling the run method of the parent class, but the class type is the child, I get the façade of this separate VI and the run method of the parent. See below (Blue class is child, red of parent).

  

  In both cases 2 and 3, I chose to put the checkbox 'See the façade when it is called' a FAKE, but still the front panels appear.

  Someone don't know either: i) the use in the executable version of the options to generate an executable when a different class method is used, or ii) when you compile an executable file with a certain start VI, to not show this starting VI?

  I understand if I say "you want to configure the RUN method of the class as 'start-up VI' in the EXE file, but it should run the RUN method for a child object"?

  If this is correct, your third approach is the right one. This new boot VI is often used as 'Splash Screen' that covers the task of a demon "spawning" for your application.

  You must simply close this VI once it's over. This can be done using VI server on its own front panel functions.

  hope this helps,

• import a class: how many ways are there? CFC, import, extend the base class

  How many ways is there to import a class and am I confused

  1 screen/public class extends MovieClip

  This inherits all the properties and methods of the MovieClip class so WHY again do we use: import flash.display.MovieClip;

  Import something else or just made the job twice

  2 import flash.display.MovieClip - so no need to extend (repeat me once again - see 1)

  3 CFCS: connect to a CFC

  4. stir in a SWF with a meta tag

  5. in the properties panel menu - add a class as a base class

  OMG - a bit confusing

  You can only "extend" another class if the compiler knows where he is.

  The import statement is only by the compiler to find the class on your hard drive.

  It is not "import" of the entire class in the sense that you import a BMP in Photoshop.
