CodeModuleManager.createNewModule and Class.forName

• CodeModuleManager and Class.forName

  I have a specific question.

  My application download both modules and install them.  Both modules are libraries.

  Module 1: Library without any dependencies.

  Module 2: Library that depends on another Module 1 and Module already installed.

  I have install the module 1 and then install the module 2.

  At this point if I call Class.forName ("class of module 1"), everything works.

  If I call Class.forName ("module class 2"), he throws ClassNotFoundException.

  Any ideas?

  The modules are correct return codes when installed CMM and make their appearance in the list of modules.  They are both duly signed.

  Note, installation from CMM requires a restart and the same problem occurs after restarting the device.

  It seems so be that module 1 using code RTT required.  After fixing that Module 2 is loaded...

• Class.forName throws ClassNotFoundException

  I encountered a similar problem as the display thread: http://supportforums.blackberry.com/t5/Java-Development/CodeModuleManager-and-Class-forName/m-p/6338...

  However, the solution for the first display does not solve my problem, or maybe I'm not clearly understand. I decided to open a new thread and want to help with.

  My workspace contains three projects: main project which is BB application, module 1 is a library and acts as an interface between the main project and module 2. module 2 is a library as well and depends on module 1. I want to create an instance of module 2, if a third-party driver is installed on the device; otherwise, just use module 1.

  After you install applications on the real BB and with thirdpartydriver installed, if I call Class.forname ("class of module 1"), it works for me, however, if I call Class.forname ("module class 2"), it still throws ClassNotFoundException.

  The application works very well on Simulator

  The three projects are properly built and signed.

  Thanks in advance for any help coming.

  Solution found:

  Adding a control RIM API dummy in all libraries depended to force RRT code signing enabled for all libraries solved my problem.

  Thanks for all the answers.

• I need help with the use of Class.forName and getResourceAsStream

  I am trying to write code that will play an audio file. All references I found the point of code as follows...

                            Class dir = Class.forName("lib.testother");
                              InputStream input = dir.getResourceAsStream("/explosion.aac");
                              Player player =
                                  javax.microedition.media.Manager.createPlayer(input, "audio/aac");
                              player.realize();
                              VolumeControl vol = getVolumeControl(player);
                              if (vol != null)
                              {
                                  int volume = vol.getLevel();
                                  vol.setLevel(volume);
                              }
                              player.prefetch();
                              player.start();
  

  I use Blackberry JDE. Now, I'm supposed to put the audio file of the project?

  Second, how then use the class.forName function? I put the audio file as a member of the project and then tried the above code and I get that it can not find lib.testother (which is the path of the code).

  If I use getClass() instead of dir above, getResourceAsStream returns null.

  Are there examples of the use of these or how to include the audio in your project... from end-to-end. The code snippet above is all I could find and it isn't enough.

• Error in CodeModuleManager.createNewModule

  I am trying to install a great MIDP application. The size of the cod is 382976. I'm installing with brothers and sisters. I tried 2 approaches

  1. start by creating an 'empty' Cod

  int handle = CodeModuleManager.createNewModule (totalsize);

  and

  handle CodeModuleManager.createNewModule = int (382976);

  the two approaches returns a handle zero

  handle int = CodeModuleManager.createNewModule (3000);

  Returns a nonzero value

  I also tried to creat the first segment of brother to the first call

  handle CodeModuleManager.createNewModule = int (totalsize, codInfo [0] .getCodfile (), codInfo [0] .getCodsize ());

  It also gives a handful of zero.

  I'm running on the Simulator. The great app installs ok when using other methods

  Published:

  Code works for a small application

  The method to write a cod 'chunks' separate module described in th api documentation does simply not.

  2 methods are indicated. The two shows that keep you track of the offset where to add the 'pieces '.

  To write the first data segment, call CodeModuleManager.createNewModule (int totalLength data byte [], int length).

  To write the second segment of data, call CodeModuleManager.writeNewModule (byte [], int newModuleOffset, int newModuleHandle, int length data).

  I do not understand 'totalLength"in any other manner to the length of the cod 'total '.

  The other way is a slight variant and begins by clarifying just size and no data.

  Create a module without data
  Call createNewModule() and provide the size of the module in bytes as a parameter.

  handle int = CodeModuleManager.createNewModule (3000);

  Here, I read 'the size of the module' as the size of the complete module cod.

  They may fail if the 'size' is great giving a handle = 0;

  What works is the way it is described in the sample

  http://supportforums.BlackBerry.com/T5/Java-development/programmatically-install-and-upgrade-Applica...

  It's a completely different way that is described in the API, you don't need to keep track of offset where to place the 'pieces' and you don't need to provide information 'length '.

  The description of the API is simply fake and do not work and the same documentation is in API for 6.

• Class.forName in jdbc

  Hello
  
  I know that this has been discussed a few times before but I'm still not clear on this.
  
  Why do we Class.forName while the implementation of jdbc.
  
  In which case it is for the class loading, why have we not need for another class. How reactivates JVM knows how to find the class and load it when we pray for the other classes.
  
  (I understand that calling Class.forName calls the static method in this document, which records the pilot as a driver available in the DriverManager class, but my question is why do we need to load jdbc class and not for others).
  
  Any response will be a great help.

  Using Class.forName (or the service-loader) allows the use of drivers that did not exist when the program was written

  If they existed or not, the point key here (and I completely missed during the validation of my answer) is that you can see what driver use prior to execution, which means that your application can be run against DBs from different vendors without any code changes.

• load the .jar and .class in MX7

  I have a cfx tag that includes a .class and .jar file. I could do on the old Server MX but in MX7, the option is not in cfide/administrator.
  I copied the .class and .jar files in the c:\cfusionmx7\runtime\lib\ directory and then added at the end of the file with the following entry. (Note: the .jar file is called MYNEWFILE.jar)
  
  Java.class.Path = {application. Home} / Servers/lib, {application. Home} /... / lib/macromedia_driver s.jar,{application.home}/lib/cfmx_mbean.jar,{application.home}/lib,{application.home}/lib/ MYNEWFILE.jar,{application.home}/... / wwwroot/WEB-INF/lib /.
  
  Then, I rebooted the server. I also have a ".class" file that goes with this. I don't know where to put this thing. Cfx (that I traced to the administrator).

• Functions variables (and Classes)

  Hi, I was wondering if ActionScript was a way to call functions and classes of variables, as they do in PHP:

  function funcname() {
       print "Potatoes come from tree";
  }
  $function = "funcname";
  
  print $function;   // Prints out "funcname"
  $$function();      // Prints out "Potatoes come from tree"
  

  Where you don't know the syntax of PHP, you should know that all perpended with a symbol $ is a variable. Is something like this possible with ActionScript?

  Flash uses array notation to convert strings into objects:

  function funcname() {
       trace("Potatoes come from tree");
  }
  var fS:String = "funcname";this[fS]();
  

• RD640 - Easy management, WMI namespace and classes of voltage, power supply, temperature and related areas

  I try to use WMI to access the material on RD640, like the easy way to manage information.

  Is this possible? If so if there any WMI information (names/classes/properties space) which is available? Or if WMI is not supported so is there another propertariy API?

  How Easy managing access the statues and RD640 material information?

  Hello bkao,

  Unfortunately the use of WMI is not a supported method. However, you can use IPMI calls for information. In my view, that is how it is easy gale gathers information (using IPMI calls).

• List full names and class IDS

  Is there a complete list of all the built-in class IDs with their names in programming?

  I looked at the help page of the ID LV2012 class property located here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvprop/gen_class_id/, but it's incomplete. For example, the RadioButtonsControl has a 72 ID and is not listed.

  Hi everyone , hope you can help me with this...

  At the end of your thread, you can push the screen with:

• Legacy and Class.getConstructor

  Hello Java community.

  I use Class.getConstructor because I don't know what case I need until execution.

  I have a class A with an A (Type1) constructor. Type2 extends Type1. Now, when I call A (Type2), the compiler I have actually been calling the constructor has (Type1) because there is no such thing as A (Type2). However, when I call A.class.getConstructor (Type2.class), I get a runtime error saying that manufacturer that there is no such thing as a (type2). I can understand why this is happening, but I still want to provide a parameter of a subtype, and so that the runtime required manufacturer intuit...

  I don't really know what kind of Builder, I need running (the call simplified to getConstructor above is only to indicate what is happening in my code) and I do not know if, for example, I will be instantiated an object of a subclass of A, or by using a setting of a subclass of Type1 (Type2, say, in the example). How to do a similar thing to arrive on time as this happens at the time of the compilation of performance?

  Thanks for the help,

  Owen.

• Memory use and class of the custom movie clip?

  Hello

  I need to create instances of a clip 100. Is it better to add functions for these clips in the movie clip class or in a separate category?

  For example, I move(), setPosition(), setRotation() functions, would be that create these features a hundred times and held memory or just reference functions? What could be better?

  Thank you

  There is a slight advantage to create a function to handle all objects of class vs each class having its own class.  but it's such a small benefit that's not worth it to sacrifice any principle of encapsulation, so you should let each Member of the class to use the class methods.
