• How do you see the System.out.println (without using Eclipse and BlackBerry JDE)

  Hi all

  I just want to know if there is no solution to see System.out.println.

  I use neither Eclipse nor BlackBerry JDE for my development.

  I have my jar, jad files. I convert my jar file using the CAP tool. The .cod files are generated.

  I start the trainer. Now I have 2 windows: Windows Simulor and the output (see picture).

  Then I load my .cod files. But I see not all System.out.println ("...") in the output windows.

  

  How can I see these System.out.println ("...")?

  Please help me.

  Thank you all.

  Thanks for your help.

  I try your solution EventLogger.

  But I have another problem:

  My request is not a native application (it is a midlet in J2ME, not a UIApplication). Do you think that it will work with EventLogger?

  How can I make a registry for EventLogger:

  static boolean	register(long guid, String name)  Registers the name and the guid of the calling application.
  static boolean	register(long guid, String name, int viewerType)

• System.out.println in the controller log

  Where can I find the exit from my System.out.println calls made in my controller?  I looked in the logs and diagnostics but did not meet my output.  When I run into JDeveloper, they are found in the built-in console OC4J tab.  So I know they work.  I can't find the on the server.

  Thank you

• Strange problem of Debug with System.out.println

  Hello

  I have an interesting question that I have not been able to solve and I reach out for more help.

  Earlier today my app stopped writing System.out.println messages in the console.

  It is not a fact that I'm not running it in debug mode, because all debugging information is still there. I see that things get focus, etc.

  But none of my system.out.println messages are written.

  Even with System.out.println ("main entry method"); on the first line of the main method does not appear.

  Is this a problem with the Simulator?

  Restart the Simulator, restart eclipse and restarted my computer, I tried the Simulator, cleaning.

  I use 8900 Blackberry Simulator.

  Any help you offer is very appretiated!

  Updated, I guess I was a bit premature in posting about me.

  After rebooting my computer again, by disabling the Simulator a few times and restart Eclipse once again, its started to work again.

  Strange strange question...

  Well, ~ FIXED ~

• System.out.println () + Eclipse + Simulator

  I expected that System.out.println () would be exit in the Blackberry Simulator output Console, but I don't get anything in this window.  Y at - there a trick to getting the output here?

  Thanks in advance,

  You must attach the Simulator in debug mode. To do this simply right click on the project > Debug as > BlackBerry Simulator. That should fix the Simulator for the Eclipse JDE plugin and println (s) should now appear in the Console output for the Blackberry Simulator.

  To connect a device in debug mode, right-click on the project > Debug as > BlackBerry device. It attach the unit to the Eclipse JDE plugin and as above, println (s) should appear in the Console output for the Blackberry Simulator.

• System.out.println)

  I have a question.
  I tend to use a lot of System.out.println () in my codes for debugging purposes.
  Now, when we deploy our code in the case of Oracle applications, what happens to these System.out.println ()?

  Hi pradeep,.

  System.out.println () does not store the output anywhere in the server.
  But as Summit says that this unnecessary code lead to performance problems.

  There is only one output and one error in the JVM. Multiple threads calling these methods must be synchronized and will potentially block. Also in production (iAS 1,0.2.2.2), STD on is not to redirect to a file and is lost.

• Custom defined function and "System.out.println".

  Hello
  
  After some cdf sample looking on the web and bring them to work on my development machine, I was wondering if the many order System.out.println (...) in the java classes indeed out there messages to. I wasn't able to find them in all the log files, I was looking at, IE. or ESSBASE. JOURNAL, or the exemple.log where I was testing the functions.
  
  Someone at - it an idea where messages from System.out.println (...) Finally end and that there is a log file containing these messages.

  Hello

  Try to run essbase in a command window (run it from the start menu or type essbase on windows OS) and not as a service, then you should see the output of the command in the window.

• Get java & quot; System.out.println & quot; content in a CF model

  All,
  I am a newbie to CF/JAVA integration and inherited about 20 java applications that are called from a template CF. abounding in all the java code (in hundreds of places) it is System.out.println () statements. So far I have not been able to get this output to display on the web page.
  
  CF Code:
  
  < CFSET UploadName = UploadsDir & "-" & cffile.serverFile >
  < CFSET ExceptionName = UploadsDir & "-" & ExPrefix & BaseName >
  < cfobject type = 'java' name = "UploadObject" class = "UploadProgram" action = "crΘer" >
  < cfset params = ArrayNew (1) >
  < cfset params [1] = UploadName >
  < cfset params [2] = ExceptionName >
  #UploadObject.main (params) #.
  
  Excerpt from Java:
  
  System.out.println("");
  System.out.println (recCount + "entry" records);
  System.out.println (hdrCount + "header");
  System.out.println ("good" account +);
  System.out.println (errCount + "bad");
  System.out.println (ignCount + "ignored");
  System.out.println("");
  System.out.Flush ();
  
  Any help will be appreciated. Thank you!
  
  

  I have it!

  I finally understand how to redirect the output stream, then return the var. toString().

  Java:

  public static main (String [] args) String
  throws the Exception
  {
  ByteArrayOutputStream outstream = new ByteArrayOutputStream();
  PrintStream ps = new PrintStream (outstream);
  System.setOut (ps);

  If (args.length< 1="">
  {
  System.out.println ("use: java InetLoad inet_sales_spreadsheet");
  Return (outStream.ToString ());
  }
  inetLoad.run ();
  Return (outStream.ToString ());
  }

  CF:

  
  #UploadObject.main (params) #.
  

  Time for a beer.

• System.out.println (significantly) slows an application?

  I couldn't find any other posts about this, but I've always wondered to this topic.  Of course if you have the debug window open and print much info, it certainly slows down due to the scrolling in the IDE.  However, it affects the application once it is on the device and is not being debugged via USB?

  The guys take off your println when you compress your code for immediate release?

  From my experience, this output does not slow down the program significantly when running on the device. I think the BONE to eat out if there is no connection of USB debugging.

  That said, we take 'more' these lines for a production version.

• How do you see the System.out.print?

             ButtonField getAdmire = new ButtonField("Button!", ButtonField.FIELD_HCENTER);
              getAdmire.setChangeListener(new FieldChangeListener() {
                  public void fieldChanged(Field field, int context) {
                      ButtonField buttonField = (ButtonField) field;
                      System.out.println("Button pressed: " + buttonField.getLabel());
                  }
              });
  

  I don't see the printing output in the console, I use the plugin for Eclipse for some reason any... Any ideas?

  I found the solution:

  You will need to run it in the debugger mode! As simple as that!

• println method static of System.out?

  In Lesson 1-5, the System.out::println is an example of a reference to a static method, (~ 5 min)

  But it seems to me that println is a non-static method of PrintStream (PrintStream (Java Platform SE 8) (System.out is an instance of PrintStream))

  I'm wrong or have I missed something?

  You are right; println is not a static method, whereas System.out is a static variable, which may be where the confusion arises. I posted a similar request on this a few days ago. You can hear some hesitancy in the audio at that point, where I suspect an element of doubt has crept in Simon's mind as it has been described.

  Another example would use something like the whole parseInt method, as I suggested to my request.

• Registration of the Client Push BlackBerry rejected by the server

  Hi all

  Successfully, I registered for the blackberry push service assessment and received the appropriate credentials.

  However, whenever I try to save my client push service, I have developed with the help of a real device, I get a "rejected by Server error."

  I've only got my credentials 5 days ago, so I don't think that it has expired.

  I use a blackberry 9700 OS 6 to test this.

  The Client I wrote is a variant of the client Push service example.

  Here is the registration code.

  public void register() throws Exception {
          ApplicationDescriptor ad = ApplicationDescriptor.currentApplicationDescriptor();
          //byte serverType = PushApplicationDescriptor.SERVER_TYPE_BPAS;
          PushApplicationDescriptor pad = new PushApplicationDescriptor( PushConfig.APP_ID, PushConfig.PORT,
                  PushConfig.REG_URL, PushApplicationDescriptor.SERVER_TYPE_BPAS, ad );
          // check whether already registered or registration pending
          PushApplicationStatus pushApplicationStatus = PushApplicationRegistry.getStatus( pad );
          byte pasStatus = pushApplicationStatus.getStatus();
          System.out.println("Starting Registration");
          if( pasStatus == PushApplicationStatus.STATUS_ACTIVE ) {
              Subscriber subscriber = new Subscriber();
              subscriber.subscribe();//register again but don't block.
              System.out.println("successful registration");
              return;
  
          } else if( pasStatus == PushApplicationStatus.STATUS_PENDING ) {
              // we already scheduled registration, wait for its result
              print("Registration pending");
          } else {
              // not registered yet, register
              System.out.println("not registered yet");
              PushApplicationRegistry.registerApplication( pad );
          }
          parseRegistrationResult();
      }
  

  In the onStatusChange(), I have this:

  public void onStatusChange(PushApplicationStatus pushAppStatus) {
          byte bpsStatus = pushAppStatus.getStatus();
          byte regReason = pushAppStatus.getReason();
          String error = pushAppStatus.getError();
  
          boolean simChanged = false;
          _regStatus = bpsStatus;
  
          switch( bpsStatus ) {
              case PushApplicationStatus.STATUS_ACTIVE:
                  Subscriber subscriber = new Subscriber();
                  String result = "";
  
                  subscriber.subscribe(); //initiate subscription
                  result = subscriber.getResult();
                  print("result is "+ result);
                  if(result == "s") {
                      print("Whoop!")
                  } else {
                      print("we failed");
                  }
                  break;
              case PushApplicationStatus.STATUS_FAILED:
                  print("registration failed");
                  displayMessage("registration failed");
              case PushApplicationStatus.STATUS_NOT_REGISTERED:
                  switch( regReason ) {
                      case PushApplicationStatus.REASON_SIM_CHANGE:
                          simChanged = true;
                          break;
                      case PushApplicationStatus.REASON_REJECTED_BY_SERVER:
                          print("Rejected By server");
                          displayMessage("Rejected by server " + error);
                          break;
                      case PushApplicationStatus.REASON_NETWORK_ERROR:
                          print("network error");
                          displayMessage("Network error");
                      case PushApplicationStatus.REASON_INVALID_PARAMETERS:
                          // registration failed
                          break;
                  }
                  break;
              case PushApplicationStatus.STATUS_PENDING:
                  print("still pending");

                  break;
          }

• How to put text on the image of blackberry?

  I'm a Blackberry app. In my application I need to show show text in an image. So I used this code.

  tab1 = new LabelField ("Page 1", LabelField.FOCUSABLE |) LabelField.HIGHLIGHT_SELECT) {}

  protected void paintBackground (Graphics g) {}
  TODO self-generating method stub
  super.paintBackground (g);
  EncodedImage tmpimg = EncodedImage.getEncodedImageResource ("ic_menu_refresh.png");
  try {}
  g.drawImage (0, 0, 70, 40, tmpimg, 0, 0, 0);

  }
  {} catch (IllegalArgumentException iae)
  System.out.println ("bad arguments.");
  }
  }

  Protected Sub layout (int width, int height) {}
  Super.Layout (width, height);
  setExtent (70, 40);
  };

  Protected Sub paint (figure net.rim.device.api.ui.Graphics) {}
  graphics.setColor (Color.WHITE);
  Super.Paint (Graphics);
  };

  };

  This code text giving on image but I want that this text not on the center of the image. I want it on the bottom of the image. I also want to resize the image depends on the size of labelfield... Please help me friends...

  I'm curious to know why you want to avoid having a VerticalFieldManager? It's a standard way of BlackBerry to arrange fields and managers vertically. He respects the flags of horizontal alignment (FIELD_LEFT, FIELD_HCENTER and FIELD_RIGHT) for "children" and does not take into account all verticals (naturally!).

  It also respects the margins of fields, which is a huge advantage - you just put properly and let the BlackBerry primitives to take care of the presentation of the screen for you. Don't try to reinvent the wheel - channel your time and energy into the functional parts of your application.

• How to find information printed by system.out?

  Hi, I am a newbie in BB dev, I have an app that will be released some info using system.out.print, but I don't know where to check in real device or Simulator, can someone help?

  In JDE when running in the menu "Build-> equip all and run" a new window will appear.

  When you run your application - have a look at this new window (or frame).

  All your System.out.println () messages will appear in this window.

  You can also open this window (if closed) via the menu: "View-> output".

  If you want to save the request stream using the following class instead of System.out.println () call:

  net.rim.device.api.system.EventLogger
  

  To open the log on the real device, press 'Alt' on the keyboard, hold down and press the keys: LGLG
