• TFLN startup error: class 'net.rim.blackberry.api.homescreen.HomeScreen' not found

  I am beta testing my app and it works fine for me in all simulators and a 9530 Storm. But one of my beta testers reported the app doesn't launch and gets the error:

  TFLN startup error: class 'net.rim.blackberry.api.homescreen.HomeScreen' not found

  I can't imagine how that could happen. Any ideas? Thanks in advance.

• Why not use the static methods - example

  Hello world
  
  I would like to continue the below thread about "why not use static methods.
  Why not use the static methods
  with the concrete example.
  
  In my small application, I need to be able to send keystrokes. (java.awt.Robot class is used for this)
  I created the following class for these "operations" with static methods:
  

  public class KeyboardInput {
  
       private static Robot r;
       static {
            try {
                 r = new Robot();
            } catch (AWTException e) {
                 throw new RuntimeException(e + "Robot couldn't be initialized.");
            }
       }
       
       public static void wait(int millis){
            r.delay(millis);
       }
       
       public static void copy() {
            r.keyPress(KeyEvent.VK_CONTROL);
            r.keyPress(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_C);
            r.keyRelease(KeyEvent.VK_CONTROL);
       }
  
       public static void altTab() {
            r.keyPress(KeyEvent.VK_ALT);
            r.keyPress(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_TAB);
            r.keyRelease(KeyEvent.VK_ALT);
       }
  
                 // more methods like  paste(), tab(), shiftTab(), rightArrow()
  }

  You think it's a good solution? How could it be improved? I saw something Singleton vs somewhere of static methods. Wouldn't be better to use Singleton?
  
  Thanks for your comments in advance.

  Maheshguruswamy thanks for the tips on the steps create a singleton of this class.
  Perhaps you could say also why do you say that it would be preferable to use singleton? What is behind it? Thank you!

  In short, it seems to me that a single instance of your class will be able to coordinate actions across your entire application. If a singleton should be sufficient.

  But who doesn't answer why he expected prefer a singleton instead of a bunch of static methods. Functionally, the two are almost identical. In both cases, there is that a single 'thing' to call methods - either a single instance of the class or the class itself.

  To answer the question, the main reason to use a Singleton on a class of static methods is the same reason readers much of not static vs static decisions: polymorphism.

  If you use a Singleton (and and interface), you can do something like this:

  KeyboardInput kbi = get_some_instance_of_some_class_that_implements_KeyboardInput_somehow_maybe_from_a_factory();
  

  And then everything calling public methods of KBI has to know that there an implementor of this interface, without worrying about what concrete class is, and you can replace some implementation is appropriate in a given context. If you do not need to do, then the approach of the static method is probably enough.

  There are other reasons that may suggest a Singleton - serialization, persistence, use as a JavaBean pop to mind - but they are less frequent and less convincing in my experience.

  And finally, if this thing keeps updated a State between method calls, even if you can manage it with static member variables, it is more in line with the OO paradigm to make them non-static fields of an instance of this class.

• Class 'net.rim.device.api.ui.TouchEvent' not found

  I built the demo using the JDE 4.7.0.41 TicTacToeDemo application and tested using the simmulator without problem. Also, I do not change a signle code line.

  I also loaded on my phone, and when you start it on my phone, I got the following error:

  Error Starting TicTacToeDemo: Class 'net.rim.device.api.ui.TouchEvent' not found

  No idea why this error?

  You are right.  The version of the BlackBerry JDE must be equal or lower than the software version of terminal Blackberry target.  The following link explains it further.

• 'net.rim.device.api.math.Fixed32' not found

  I left work last night, and my app works perfectly well in the SIM card.  No problems.

  Just today, initialize the SIM card and get this:

  'net.rim.device.api.math.Fixed32' not found

  I use Fixed32 to resize an image.  It is imported successfully and not showing ANY error in the project.

  He did this on more than 1 Simulator.

  Any ideas?

  I tried to move it manually in the API, without success.

  These types of errors are usually caused by using a version of BlackBerry Java SDK/BlackBerry JDE, which is not supported by the version of the BlackBerry Smartphone you run it on.

• net.rim.device.api.ui.decor.Background not available in Eclipse?

  Hi, I use Eclipse (v3.4.1) and therfore installed JDE plug-in for Eclipse version 1.0.0.67 has the Blackberry JDE 4.5.0 component Package.

  I checked JDE 4.5.0 and I know he has the base class because it doesn't even have the package of net.rim.device.api.ui.decor

  What I'm trying to do, is simply to add a LabelField to a title bar that has a PNG file as a background?  Is there a work around for this without having to make my own Field object?

  See you soon.

  Hello

  OS 4.5.x has not décor package yet. It was added only in 4.6 or later. So if you need to write your application for 4.5, you must implement your own domain, possibly replace methods paint (...) and (...) layout of fields.

  If you like about 4.5 and I want to just write your application to 4.6 or higher version, you will need to install the component via the Eclipse Update site 4.6 package. After successful installation, you can switch to the package of 4.6 component via preferences-> settings BlackBerry workspace.

  Hope this helps,

• ScalableGraphics and net.rim.device.api.ui.Graphics

  I was robbed on a bug in my SVG code for too long and now, I discovered that I can use the bad Graphics class.

  ------------SNIP------------------------
          scalablegraphics.bindTarget(graphics);
  
          for(int i=0;i
  In the method object, I'm rendering SVG standard above that works for a little while and finally fails.  I am hunting the failure on mine, but in the process I've stumbled upon the documentation that call the bindTarget(Graphics g) aims to link to one of these graphics implementations:
  (From JDE 4.7 of the ScalableGraphics class documentation, whether)
  The type of the Graphics object depends on the Java profile that this specification is implemented, as follows:
  javax.microedition.lcdui.Graphics on profiles support LCDUI;
  java.awt.Graphics on profiles supporting AWT;
  either of the above on the profiles of LCDUI and AWT support.
  My questions to the people here:
  is this simply an artifact of Sun Java documentation not updated to include the "net.rim.device.api.ui.Graphics" as a viable link?
  It's pure chance that SVG seems to work with the class Graphics RIM?
  Everyone uses the class Graphics RIM with SVG?
  Thank you
  Mike
  			 
  It is a question of JavaDoc, which I have updated you.  The net.rim.device.api.ui.Graphics class is supported here.
  Can you elaborate on what stops working?  What model of smartphone BlackBerry and the version of the software BlackBerry device test you on?  You can find this under Options, all on the BlackBerry Smartphone.

  Sergio,
  good work, now I can read the code :-)
  Strange, nothing appears immediately.
  The buttons in the showDetailItem are the only ones who does not?
  One thing you can try is to use the visible property rather than the rendered attribute. The user interface looks the same, but the properties behave different (rendering = false means components are not on the page, visible = false means components are on the page but do not appear to the user).

• May not substitute the text format in the former document InDesing CS4...

  I opened an InDesign Cs5 document in InDesign Cs4, I created my own paragraph styles, but in trying to apply the text in the document, it will not take the police, just the colors.

  I tried to open the copy in word and Notepad, re - format, then copy and paste again in my InDesign document with no luck. I've used InDesign for many years and I never had this problem before, anyone know how to fix this?

  Thank you

  This really, really looks like there is a style of character applied to this text as well.

  (This style of character can even be selected as default, so whenever you are trying to overwrite everything that you do is re - apply all over again.)

• Instantiate using 'new' does not not on the init() method

  Hello

  I am instantiating an object using "new" and calling my init() with 4 parameter passing constructor, but I get the error message that the parameters are required (see below). It works by using "createobject", that's fine, but I wanted to use 'new' to create an object. Can someone give some info why it doesn't work? Thank you.

  The SHOPPINGCARTDSN parameter to the INIT function is required but is not passed in.

  < cfscript >
  o = new cfc.shop.discount () .init (shoppingcartdsn: 'test', localDSN: 'timerDelegate', starsDSN: 'testdsn', ProjectName: 'test');
  writeDump (o);
  < / cfscript >

  You do not have to call the init method when you instantiate your object with the new. This is done by the new function itself (even with parameters, pass the parameters to the object, and not to the init function)

  Try this:

  o = new cfc.shop.discount (shoppingcartdsn: 'test', localDSN: 'timerDelegate', starsDSN: 'testdsn', ProjectName: 'test');

  writeDump (o);

  I have compiled the jar using jdk1.5. IM using 11G ps2. The method takes a string as input and returns a list.
  
  Thanks in advance!

  try to use the Web Console of OSB directly, it is VERY stable and well tested. Here, you have option explicit to create a resource JAR - you can't fail.
  Once do you operate in the Web Console, just the sbconfig.jar to export and import it into Eclipse.

  Honestly when I need to do something that is not the Message flows edition, I much prefer the Web Console, it is very strong (I can't say the same of the eclipse).
