  Consistency: 3.7.1.1 (windows - x 86-vs2005) x 86 release
  
  We have created a number of classes serializable C++ consistency for our project which use the COH_REGISTER_MANAGED_CLASS mechanism in their respective folders in the CPP.

  Hi DonLonDon,

  I think that what you see is a side effect of a bug fix which came in 3.7.1.1. The bug in question related to when it was safe to run the initialization code associated with things like macros COH_. Prior to p1, this was done as part of the static initialization C++ which is found to be dangerous in some environments. Beginning with 3.7.1.1 defer us initialization and lazily do it according to the needs and complete then any remaining initialization when consistency is first consulted, for example, you start using CacheFactory. I understand that for unit tests that could be problematic as you can test things that have nothing to do with the caches and thus CacheFactory. However, you can trigger the complete initialization manually if you like by calling coherence::lang:System:loadLibrary (NULL).

• BlackBerryContact.getAttributes return IllegalArgumentException

  I need to retrieve the labels of each number in the contact card:

  BlackBerryContact objBBContact = (BlackBerryContact) context;

  PIMList objPIMList = objBBContact.getPIMList ();

  int intCounter = objBBContact.countValues (BlackBerryContact.TEL);

  for (int i = 0; i)< intcounter;="">

  }

  The getAttributes throw IllegalArgumentException on the 'Mobile 2' field

  Thanks in advance

  It works on the last Simulator 4.7.1 BB 9630, maybe it's a bug in the BB 9000 Simulator.

  I have create a dialogue that, as one of these fields with the test code, like this:

          dm.add( new MultiColumnTextField( fieldData1, 2, Field.FOCUSABLE ) );
  

  But while the field height resulting seems correct, the painted 'text' seems to be very tiny boxes (as the police is too small).  But even if I Uncomment the line in the constructor that explicitly defines a larger font, there is no effect.

  Can anyone see what I'm doing wrong?

  The value of width that you specify in the drawText method is too small and the text is be cropped.

  You can use the Font.getAdvance method to determine the width of a text string.

• Plain AES using

  Hi all

  I have to use AESEncryptorEngine.encrypt () to encrypt data using the AES algorithm. But the times when I have try it, BB throws IllegalArgumentException. There is no detailed in the exception message and stacktrace.

  I've seen examples where CBCEncryptorEngine & operated PKCS5FormatterEngine with AESEncryptorEngine. It works fine, but I need to use only the AES and without fill.

  What is the wrokaround for this?

  Can you suggest me some third party encryption library. I tried the J2Me of Bouncy Castle version, it is not compiling in BB.

  Thank you.

  I think the problem here is plain and encrypted text must match the length of the block for the algorithm.  So do both these 16 bytes and do this test one another.

  Help me with this.

  I was trying to encrypt and decipher passing on it but only has failed, so I just change how to encrypt or to decrypt the password. I had just use Base64Coder class to achieve this. And thank you for your concern. And here is the Base64Coder class, if someone needs it.

• BY buying getTransactionId() get set to zero

  Hello friends,

  I do to purchase the app. purchase of work id very well. but is problem when I use getTransactionId(). I get 0.

  my code is below.

              System.out.println("***************startPurchase retrn true************************");
              return true;
        }
  

  I get a value of 0 when I use the purchase.getTransactionID (); What should I do? like in years...

  Thank you and best regards,

  Ajay Patil.

  If indeed, you post your sales request, download from outside the sandbox and actually buy a digital camera, then you should receive a valid Transaction ID.

• the value of the digital inputs to change the field

  Hi all

  I have an edit field that has a digital text filter that only accepts phone numbers. Users have the choice to load these numbers from address book or direct entry.

  I used the digital filter to allow only numbers. .

  But when I tried to load these address book.  with editField.setText (phoneNum); It is to throw IllegalArgumentException.

  How to set digital inputs to the editField?

  Hi thanks for all your entries!

  My issued are resolved. I used BasicEditField aulieude EditField to solve this problem. the basicedit field allows the digital text and it solved the problem.

  Thanks for all your interest...

• Format a decimal number (#, #. #)

  Hello

  I'm doing something pretty simple using the RIM Blackberry APIs - I have a "1000000" string, I want to put in the form of "1 000 000,00.

  I tried the two classes of the RIM API to do this, but none of them have what I actually need:

  1. javax.microedition.global.Formatter

  String value = "1000000";
  float floatValue = Float.parseFloat(value);
  Formatter f = new Formatter(); //also tried with locale specified - Formatter("en")
  String result = f.formatNumber(floatValue, 2);
  

  The result variable is "1000000.00" - there decimal and group separators (comma) is missing.

  2 net.rim.device.api.i18n.MessageFormat (claims to be compatible with in the standard Java edition java.text.MessageFormat)

  String value = "1000000";
  Object[] objs = {value};
  
  MessageFormat mfPlain = new MessageFormat("{0}");
  MessageFormat mfWithFormat = new MessageFormat("{0,number,###,###.##}");
  
  String result1 = mfPlain.format(objs)
  String result2 = mfWithFormat.format(objs)
  

  performance(1): (what mfWithFormat disabled) gives me just a simple '1000000' (as expected, but useless).

  Result2: throws IllegalArgumentException.

  At this point, I am out of options what to try next...

  Any suggestions?

  Thank you

• EditField problem!

  Hi every1

  I was faced with a problem when adding a text field on screen.

  When I'm trying to add a field for a GridFieldmanager editing, I m getting an EXCEPTION 'ILLEGALARGUMENT' and ending of app.

  Here I m using the object persistent 2 store text in of editfield

  Infact I m error, when I m 2 access the same screen twice, by train, but not in the first attempt. Initially I m 2 can access screen with success, but in my second attempt I m get error at the particular point dat dat

  Help me... Urgent!

  Concerning

  Kiran

  http://www.BlackBerry.com/developers/docs/6.0.0api/NET/rim/device/API/UI/component/BasicEditField.ht...

  Throws:
  IllegalArgumentException - if the text cannot be entered in an edit field.

  My guess would be that you have a filter set on the field and try to define a text that is in conflict with it, but without more information, it is difficult to say.

• Logging class and LoggingPermission

  I have a question on logging and the code generated by NetBeans code completion.

  When you need to surround a piece of code with a try-catch block (see below) and do you this by leaving NetBeans to generate, the catch block inserts code using the logging class.  By default, this action adds also the necessary authorization for the project.  I guess I have to assign java.util.logging.LoggingPermission, but I don't know what values to put in other areas (see below) of the dialog box.  They are not the same as the other permissions that we put in this category.  I would also like to know where it is established if you know.

  import java.util.logging.Level;
  import java.util.logging.Logger;
  
  

          try {
              recordStore = RecordStore.openRecordStore(storeName, true);
          } catch (RecordStoreException ex) {
              Logger.getLogger(RMSPersistentStore.class.getName()).log(Level.SEVERE, null, ex);
          }
  

  Under the project - Application Descriptor-> API permissions properties

  Authorization: java.util.logging.LoggingPermission

  Protected the name of the resource:

  Action requested:

  I'm curious to see how this logging works vs using System.out.println () or System.out.format ()...

  Thank you

  
  Brent S

  Thanks Trinity!

  I had actually read it, but I didn't quite connect the dots.

  public LoggingPermission (String name, String actions) throws IllegalArgumentException

  Parameters: name -the name of the permission. Must be 'control '. actions-Must be null or an empty string.

  When you set permissions for logging I was looking for Permission:, name of the protected resource:, & shares: with this designation by the dialog box fields.  I should have read more closely and extrapolated a little better!

  Thanks again,

  Brent S

• simple method of max

  Hello
  
  I'm doing a simple method that returns the maximum element of an array of int. (I got this question on an interview.)
  I want to do it properly, so my question is what do I do if the table is null? Is there a common solution, best practices for this?
  Can I use try-catch block for NullPointerException or just an if-else?
  
  Also please tell me if my method is correct otherwise.
  
  Thank you!
  

       public static int max(int[] arr) {
  
            if (arr == null) {
                 ????  //System.out.println("array is null");
                 ????  //return Integer.MIN_VALUE;
            } else {
                 int temp = Integer.MIN_VALUE;
                 for (int i : arr) {

  It depends on the specific context, but have no other details, I'd throw an IllegalArgumentException or NullPointerExcecption. I'd also throw IllegalArgumentException if the array has zero element.

  I certainly would NOT return any value unless the requirements specifically said that this is the desired behavior.

  Also please tell me if my method is correct otherwise.

  The loop to find the max value in the case of a valid table looks good. The only things I would change are:

  (1) rename the temp into something more meaningful, such as max or result.

  2) put braces around the temp = i body of the if (I > temp) test. They are not strictly necessary, but I (and most of the people I know) feel better to always use. Avoids confusion, makes it clear that you really don't want only this line in the body and prevents the error from adding more lines later and forget to add the braces.

  The Pref class is not supported in Oracle. So I used Java SP for BACK orders executed and calling in turn REG QUERY command.
  Tested with Windows 2003, Win XP and Win Vista (32-bit).

• BUG + PATCH: SecondaryKeyCreator went from partial data

  If you put a DatabaseEntry containing only partial in a main database data, and this primary database has an associated secondary database, then when the secondary key is be recalculated the SecondaryKeyCreator is given to the same object of DatabaseEntry partial instead of a 'merged' new DatabaseEntry containing the new value of entire data updated.
  
  This is obviously unacceptable, because as a general rule, the secondary key may rely on all or part of the primary data, and the SecondaryKeyCreator must be able to see it all.
  
  The patch below fixes this (including some refactoring in order to eliminate duplication of code):

  You are right that it is a bug. Thank you for this comment! We will fix it in a future release.

  In the meantime I suggest to work around this by using only not a partial DatabaseEntry for methods put (), when secondary are associated with the primary database.

  Please note that using a partial DatabaseEntry for a method put () has the performance advantage very little and is very rarely used. This feature is included primarily for compatibility with the original edition of the BDB product C.
