• Call a procedure from javascript

  Hello
  
  I would like to help on the following please.
  
  I have a JavaScript in page region 'function and Global Variable declaration ':
  

  function openUrl(pUrl) {
    window.open(pUrl,"_blank","toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=yes, copyhistory=no, width=1024, height=768");
  }

  In the same page one have a number of standard reports. A number of columns in each of these reports sets a link. The binding for all the columns settings are defined as follows:

  Target: URL
  URL: javascript:openUrl('http://#SERVERNAME#:9704/xmlpserver/Publications/Dock_Report.xdo?_xpf=&_xpt=0&_xdo=%2FPublications%2FDock_Report.xdo&_xmode=4&_paramsID_USU=#ID_USU#&_paramsIDCR=#IDCR#&_paramsIDCU=#IDCU#&_xt=DPol_Layout&_xf=pdf&_xautorun=true');

  As you see, the user of the application, click on the link on the column of the report and a popup is generated showing the report. It all works very well.
  
  My requirement is to call a procedure from the augments that are included in the column link that was clicked by the user of the application.
  

  #ID_USU#
  #IDCR#
  #IDCU#

  My question is how to achieve this as the url is inside a call to javascript?
  
  Can I use the Javascritp set in the page to extract the details, and then use javascript to call a procedure?
  
  Any help, pointers, ideas, everything is welcome.
  
  Request Express 4.0.2.00.07
  
  Thank you

  Have you seen this javascript API? http://docs.Oracle.com/CD/E17556_01/doc/apirefs.40/e15519/javascript_api.htm#BGBJHEHG

  It has very convenient function: apex.submit (pOptions);

  Specify the target URL as:

  JavaScript:rowClick('#ID_USU#',_'#IDCRM#',_'#IDCU#');

  Then add a function to your page somewhere:

  function rowClick(idUsu, idcrm idcu){
  
    openUrl(/*url*/);
    apex.submit({request: "SOME_REQUEST_VALUE", set: {Px_ID_USU: idUsu, Px_IDCRM: idcrm, Px_IDCU: idcu}});
  
  }
  

  (Where you have page elements for each of the items that you want to set.

  Then you can have a process of PL/SQL page, under condition of request = expression 1, term 1 = SOME_REQUEST_VALUE

  And do you want to ;-)

• calling a method from javascript bean

  Hi forum,
  
  I was wondering if it is possible to call a method of bean managed from javascript. Why do I need it? Because I want to implement a simple javascript and light confirm dialogue resulting (Y or N) determines if the call or not a method that could achieve a vo. To be more precise, I hava a table only reading and I want to give the user the option to select a single line and remove it without taking to another page but confirming a javascript dialog box.
  Thank you very much in advance.

  Yes,

  .. You should forget about it. 10.1.3 doesn't have a callback method in controlled beans. In theory, you can create a filter for the faces servlet and pass a parameter of specific application as a flag with the request, so the filter can attempt to access the bean managed and put some information below. However, on the client side you would issue such a XMLHttpRequest

• Cannot call the functions from Javascript using ExternalInterface

  Hi all, I use external Interface to call Javascript in an HTML document with an embedded flash object, but I can't call functions in the flash JavaScript object.
  
  JavaScript:
  function call_actionscript {}
  If (document.getElementById ('flashObj')) {}
  Alert ('object flash found.');
  document.getElementById('flash2').test_from_javascript ();
  }
  }
  
  
  ActionScript:
  
  package {}
  import flash.display.MovieClip;
  to import flash.external.ExternalInterface;
  import flash.events.Event;
  
  SerializableAttribute public class extends MovieClip {} FlashObj
  public void FlashObj() {}
  ExternalInterface.addCallback("IsStatic",IsStatic) ('test_from_javascript', test_from_javascript)
  }
  
  public void test_from_javascript(e:Event):void {}
  ExternalInterface.call("saveglobalscore",score) ("alert", "javascript test received in actionscript!")
  }
  }
  }
  
  Call the "call_actionscript()" javascript function produces no result. Call Test_from_javascript() manually to code Actionscript product alert "javascript test has received in actionscript!" without problem. So the ExternalInterface.call("saveglobalscore",score) method works fine, but the the ExternalInterface.addCallback("IsStatic",IsStatic) doesn't seem to work at all. What I'm missing here?

  Try to change/add the JS in your HTML code to the following.

• make sure that the procedure, called pl/sql from apex DURATION

  Hi gang,.
  
  I was wondering what the thoughts of the people where assuring him a packaged procedure is called in a session of runtime Apex, as opposed to sql * more or elsewhere.
  
  For example, how apex_mail.send to validate and output the following if executed from sql * more:
  ORA-20001: this procedure must be called from a session of the application.
  
  A simple call to check v ('APP_USER') wouldn't is not null enough?

• call scripts sql from a trigger

  I use Oracle Data Miner 11 g in Windows 8. I want to create a trigger that will instantiate some sql scripts when it is executed (that is, whenever I try to insert update a record)
  Relaxation where will call sql scripts. The whole purpose of this is to make some process when I add tuple in the table. Can someone please help me with the correct syntax for it?
  Thank you! ~

  I'm doing some data on my set of data mining techniques. I want to run the data mining process every time I add a new tuple (i.e. record) or update.  For the data extraction process, a script is called that makes data mining and stores the result in a table. That's why I came up with a solution to trigger which in my opinion; would be the perfect way to launch the script and perform the tasks of trigger (on the infeed table) too. The goal is to automate the script to data mining.  Here's my clear understanding?

  No - your 'understanding' is NOT clear or correct.

  1. a trigger runs as PART of a transaction. It was NOT what happens in the trigger and my never be, committed in the database.

  2. that means that the session LIKE NO other can see that data and a script will not be able to access these data until it was committed.

  3. a trigger and the transaction can be rolled back and restarted several times, or can be rollbacked and terminated without a commit never happening.

  4. If all the data your script would be given mine must already exist in the database BEFORE your races and even trigger.

  So these scripts must be a completely separate WORK that run AFTER any validation occurs and the data you want to "mine" actually exist.

  NONE of this is appropriate to be initialized by a trigger, because as I said above, the relaxing activity may not even engaged.

  You must create some PL/SQL (or other) code that controls the steps that must be taken

  1 insert/update data - including your stuff to trigger if there is

  2 validate this transaction

  3 run a DBMS_SCHEDULER job to run if necessary batch files/scripts.

• Simple enough, but calling one method from another class

  Hi all
  I know it's pretty simple, even though I do not see where I am going wrong for some reason any. Basically, I have a class that extends JPanel but when I try to call one of its methods in my main class I get an error. The code (I hope) is:
  
  Main.Java

  import java.awt.BorderLayout;
  // ...
  import javax.swing.UIManager;
  
  public class Main extends JFrame implements ActionListener {
  
       JFrame frame;
       public static JPanel statusBar;
  
       public Main() {
  
            // ...
  
            // Add a status bar
            statusBar = new StatusBar();
            mainPanel.add( statusBar, BorderLayout.SOUTH );
  
            setContentPane( mainPanel );
            // ...
       }
  
       // ...
  
       public static void setStatusBarText( String s ) {
            statusBar.setStatusText("Test");
       }
  
       // ...
  }

  StatusBar.java

  import java.awt.Color;
  // ...
  import javax.swing.SwingConstants;
  
  public class StatusBar extends JPanel {
  
       private int barWidth;
       private static JLabel status;
  
       public StatusBar() {
            super();
            //barWidth = Main.getProgramWidth();
            //setPreferredSize( new Dimension(barWidth,22) );
            setLayout( new FlowLayout( FlowLayout.LEADING ) );
            setBorder( BorderFactory.createMatteBorder(1, 0, 0, 0, new Color(160,160,160) ) );
  
            status = new JLabel("Test", SwingConstants.LEFT);
            //status.setVerticalAlignment( SwingConstants.CENTER );
            add( status );
       }
  
       protected void setStatusText( String s ) {
            status.setText( s );
            revalidate();
       }
  }

  The "statusBar.setStatusText ("Test")"; call in the main class file does not work and I get the error:
  
  >
  cannot find symbol
  symbol: setStatusText (java.lang.String) method
  Location: class javax.swing.JPanel
  statusBar.setStatusText ("Test");
  >
  
  Any ideas what I am doing wrong? I created an instance of the class called status bar StatusBar, can I use it to call the setStatusText() method (via statusBar.setStatusText ()) I thought everything is OK, then it does not work? Even if there is an easier way to do what I want to achieve (i.e. to update a JLabel since the 'central' main class file instead of setting the JLabel static and have all classes call him directly), I'd be glad to know where I am going wrong here nevertheless.
  
  Thank you very much

       public static JPanel statusBar;
  
       public static void setStatusBarText( String s ) {
            statusBar.setStatusText("Test");
       }
  

  >

  symbol: setStatusText (java.lang.String) method

  statusBar.setStatusText ("Test");
  >

  The type of variable statusBar is JPanel. That's all the compiler takes into account. It is not relevant that at a certain point in the program, the type of the object pointed to by this variable is a subclass of JPanel (because at another time, it might be an instance of another subclass or JPanel itself.

• Cannot call function AS3 from JavaScript

  Hello

  I am trying to call a function in ActionScript 3 with JavaScript. The problem that I can't get one of the browsers to trigger this AS3 function. Debuggers to say that the function is not defined when I call on the flash object.

  What is supposed to happen is - the javascript function calls the AS3 function and passes an integer value.   This integer is then used to remove one of the 20 funds sovereigns and load that into the flash movie.

  Please let me know if you can think of everything I can do to make it work!  I've been blocked for hours and can't seem to get there.

  Here are my actionScript:

  import flash.net.URLRequest;

  import flash.display.Loader;

  to import flash.external.ExternalInterface;

  var movies: Array = ["idle - ok.swf ',"idle - good .swf"];

  First, it loads it "Hello swf»

  var helloLoader:Loader = new Loader();

  var helloURL:URLRequest = new URLRequest ("idleAvatar.swf");

  helloLoader.load (helloURL);

  addChild (helloLoader);

  var setAvatar:Function = loadAvatar;

  ExternalInterface.addCallback("IsStatic",IsStatic) ("callSetAvatar", setAvatar);

  Then, this function must be called by JavaScript to load one of the other sovereign wealth funds.

  function loadAvatar(indx:Number) {}

  var url: URLRequest = new URLRequest(movies[0]);

  var ldr:Loader = new Loader();

  LDR. Load (URL);

  addChild (ldr);

  }

  Here's my JavaScript:

  "<script type="text/javascript"> ".

  function callExternalInterface (val) {}
  document.getElementById("loader").callSetValue (val);
  }
  < /script >

  Here is my embed code:

  <div >

  "" " <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="250" height="350" id="charger" name="loader"> .

  " <param name="movie" value="loader.swf"/ >

  " <param name="allowscriptaccess" value="always"/ >

  <!--[if ! IE] >->

  "" <by typeobject = "application/x-shockwave-flash" data= "loader.swf" width= "250" height= "350" > ""

  " <param name="allowscriptaccess" value="always"/ >

  <!-<! [endif]-->

  " <a href="http://www.adobe.com/go/getflashplayer_fr"> ".

  " <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player"/ >

  </a>

  <!--[if ! IE] >->

  < /object >

  <!-<! [endif]-->

  < /object >

  </div>
  "<a href="#" onClick="callExternalInterface (1)' >click ON < /a > ""

  You don't appear to be calling any function in your actionscript code.  Names between and inside are in disagreement.

  document.getElementById("loader").callSetValue (val);

  must call a function identified by the string "callSetValue" in your actionscript code, but you only have an identified with "callSetAvatar" and the function associated with the one on your side AS3 is specified as setAvatar...

  ExternalInterface.addCallback("IsStatic",IsStatic) ("callSetAvatar", setAvatar);

  but you do not have a function named setAvatar, you have a named loadAvatar

  Here is a link to a tutorial that can help you see how the functions are specified between actionscript and javascript using the ExternalInterface class.  He becomes confused, I suggest that you copy the code into a word processing file, so you can put clear where they have the same language between them.

• What is the best way to optimize a SQL query: call a function or doing a join?

  Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

  It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

  If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.

  No, because you cannot expose your database server to external users. but you can call a remote method that can run your database procedures
