• Problems capturing pictures about OS6 - East System.getProperty ("video.snapshot.encodings"); valid?

  Hello

  I hope someone can help with this query.

  I use the code that is very similar to the sample application camerademo to take a photo using the camera. It works properly on devices running OS5. However, on devices running OS6 photo is just an image of white/black.

  I think I followed the problem until the encoding string passed to getSnapshot(). When I switch which must be a valid encoding string (based on the output of System.getProperty ("video.snapshot.encodings")) the captured image is a black screen. However, when I pass null to getSnapshot() it works correctly. I want to avoid using null as the captured image is much more that I need and for reasons of effectiveness, I would like to avoid having to reduce its size after the capture of the photo.

  I tested this on the 9780 Simulator. The corresponding code is included below for reference.

  Thanks in advance!

  It turns out that it was only a problem on the Simulator. I managed to get my hands on a real device 9780 and the code works fine on it.

• System.getProperty returns NULL on Simulator

  The following call:

  System.getProperty("video.snapshot.encodings")
  

  Returns a null value.

  I tried using the default Simulator of the component package 4.5.0_4.5.0.16.

  This key is available in 4.7 +. I don't know what you're trying to do, but you should know that there is no way to adjust the front camera of 4.6.

• Java 7 u45 System.getProperty returns null

  7u45 made a change that is not documented in the release notes. You must precede the properties with jnlp.myproperty in your JNLP file, unless your jnlp file is signed.

  But like me, since you can have different values in multiple deployments, signing the JNLP is impossible.

  I tried to submit a bug on this issue report, but their bug report process works as well as 7u45...

• Can not read the Oracle JVM system property unless the class is reloaded

  I want to be able to read system properties set of DBMS_JAVA .set_property of a java stored procedure. To do this, I have this simple code:

  public static String getEnvironmentVar(String propertyName) {
          return System.getProperty(propertyName);
  }
  

  When I run the present on the database, java stored procedure does not seem to load the property just has DBMS_JAVA .set_property:

  declare 
       s      varchar2(100);
  begin
       s := dbms_java.set_property('test_prop', 'test_val');
       s := getEnvironmentVar('test_prop');  -- This is my java stored proc
       dbms_output.put_line(s);
  end;
  

  However, when I reload the class in Oracle (with loadjava); the property is read correctly. Am I missing something?

  Thank you.

  If you try the declare in a new session of RDBMS, I think you'll find that it works.  Or insert the line

  s: = dbms_java.endsession;

  between the dbms_java.set_property and the getEnvironmentVar call.  When dbms_java.set_property is called, it creates a value for a property that is used only for subsequent initializations of the java VM for this session of RDBMS.  It does not affect the java VM that has already been initialized in the session, as appropriate.  If java has not been used before that in the session underway, then the virtual machine will be initialized when the getEnvironmentVar call is made and the value established earlier by dbms_java.set_property discussed.  But if java had already been used in the session, such as would happen if you had previously created or solved the class containing the method getEnvironmentVar of the session, then the value set by dbms_java.set_property is not visible (unless and until that something (like dbms_java.endsession, System.exit or an unrecoverable error) occurs to put an end to the existing java VM without end of the RDBMS session).

• How to set up a system property

  Hello world
  
  Does anyone know how to set up a system console for WebLogic 11 g property?
  
  I´d as set up a property via the web console, then get this property in my java code. Something like this:
  
  System.getProperty ("foo");
  
  Is this possible?
  
  Thank you
  
  Fernando

  Hi Fernando,

  Please see the link which tells us how we can define the JAVA_OPTIONS the administration Console...
  http://WebLogic-wonders.com/WebLogic/2010/03/26/nodemanager-based-managedservers-setting-mem_args/
  The link above demonstrate that how we define * "-the system Duser.dir property = E: / MyDirectory" *...

  Now you can set your own JAVA_OPTION as follows:

  -Dfoo = MyFooValue

  After setting above propertu in AdminConsole MEM ARGS, you must restart the server. Then, you can use the following code:

  String result = System.getProperty ("foo");

  What I need to do, is to link my path of the properties file for a global property accessible to all applications deployed on the server, in order to find the path of my applications (EJB 2.1) and access the properties without cutting the path of the properties file in the code.
  
  In jboss, I used the file "properties - service.xml", in which I can set the key/value pairs, and the key will be published to the server and available programmatically as a property system through the call "System.getProperty ().
  
  How can I do the same in weblogic 10.3?
  
  Thank you!

  Yes

  In both options... .reading the code in the file property will be the same.

  Thank you

• Examples of code to create the connection of BWS

  Hi I started using BWS (Blackberry Web Services) recently after the use of BAA (Blackberry Administration API) for some time. I would get a tutorial or sample code showing the initialization of the connection to the BWS and then use it to call the getUsersDetail method. I have the below code is missing the connection of BWS.

  import java.util.List;
  
  import com.rim.ws.enterprise.admin.*;
  public class BWSTest {
  
      public static String locale = "en_US";
      public static void main(String[] args){
  
          RequestMetadata requestMetadata = new RequestMetadata();
          requestMetadata.setLocale(locale);
          GetUsersDetailRequest userRequest = new GetUsersDetailRequest();
          userRequest.setMetadata(requestMetadata);
          userRequest.setLoadDevices(true);
          userRequest.setLoadAccounts(true);
          userRequest.setLoadITPolicies(true);
          userRequest.setLoadSWConfigs(true);
  //      List allUsers=userRequest.getUsers(); this method reflects users added as part of the request, not resulting from it
          GetUsersDetailResponse response = bws.getUsersDetail(request);
  
          if (response.getReturnStatus().getCode().compareTo("SUCCESS") !=0){
              System.out.println("Error occurred: "+response.getReturnStatus().getMessage() );
          }
  
          for(GetUsersDetailIndividualResponse individualResponse:response.getIndividualResponses()){
              individualResponse.getUserDetail().getDisplayName();
          }
  
      }
  
  }

• How to detect if the Android app is the reconditioned Blackberry version?

  My application can be easily repackaged for blackberry devices using its web portal.

  http://developer.BlackBerry.com/Android/documentation/using_the_bb_packager_1873331_11.html

  So, I can turn my .apk file in a .bar file that users can install on their devices BB10.

  My concern now would be to slightly change the user interface or disable certain features (invoicing app, Google Maps, some intentions) about the operating system.

  I should like, for example, to display a button of the card on legit Android devices and remove this button on the port of Blackberry. I also have some preferences related to the widget that have no reason to appear on a device BB10

  You know an ideal way to detect if the app is the one refurbished or the original apk?

  My guess would be to use the Build information, but I'm pretty sure that there is a better way to do this.

  Try:

      public static boolean isBlackBerry() {
          return java.lang.System.getProperty("os.name").equals("qnx");
      }
  

• How can I add pictures to the gallery and see from BlackBerry Media Center

  I want to add a file to the image to the device file system. then, he discovers the BlackBerry Media Center. I use under folder to add a picture

  System.getProperty ("fileconn.dir.photos");

  This function gives me a way and I write to the file in this folder. But, as I wrote, I have strictly see native BlackBerry support center. What should I do to see this image?

  Thank you

  The BlackBerry Media Center should be able to view all the folders.  You choose the view all the photos option?  This file you write to?  Have you tried a different folder?  What format is the image?  What model of Smartphone BlackBerry and the BlackBerry terminal software version you test on?  You can find this under Options, all on the BlackBerry Smartphone.

• Image recording is not real but device works perfectly on emulator

  Hi guys, I use the JDE 4.6.1. I would like to keep an image uploaded to the file system and retrieve it later. Something like a caching option. Everything works perfectly on the Simulator, but when I install it on the device, it does not work. Here's the code,

  private StringBuffer Imagedirectory = new StringBuffer(System.getProperty("fileconn.dir.photos"));
  
  FileConnection fc = (FileConnection)Connector.open(Imagedirectory.toString(),Connector.READ_WRITE);
  
                  if(!fc.exists()){
                      Util.getWebData(url, this);
                  }else{            
  
                      byte[] data = getData(fc);
  
                      bitmap = EncodedImage.createEncodedImage(data, 0,
                              data.length);
  
                      if(this.width !=0 && this.height !=0){
                          bitmap = ScaleImageToSize(bitmap, this.width,this.height);
                      }
                      setImage(bitmap);
   }
  

  This is where I get the data of the file

  private byte[] getData(FileConnection file)
      {
          byte[] data = new byte[0];
          try
          {
               InputStream input = file.openInputStream();
                            //////////
               int SIZE = 100000;
               ByteArrayOutputStream byteArrayOutputStream = new
                                  ByteArrayOutputStream();
               byte[] buffer = new byte[SIZE];
               while (true)
               {
                 int bytesRead = input.read( buffer, 0, SIZE );
                 if (bytesRead == -1) break;
                 byteArrayOutputStream.write( buffer, 0, bytesRead );
               }
               data = byteArrayOutputStream.toByteArray();
               byteArrayOutputStream.flush();
               byteArrayOutputStream.close();
  
          }
          catch(Exception e)
          {
              System.out.println(e.toString());
          }
          return data;
  
      }
  

  This is where I write the image to a file,

  private void writeFile(byte[] data, String fileName)
      {
          FileConnection fconn = null;
          try {
              fconn = (FileConnection) Connector.open(fileName,
                      Connector.READ_WRITE);
          } catch (IOException e) {
              System.out.print("Error opening file");
          }
  
          if (fconn.exists())
              try {
                  fconn.delete();
              } catch (IOException e) {
                  System.out.print("Error deleting file");
              }
              try {
                  fconn.create();
              } catch (IOException e) {
                  System.out.print("Error creating file");
              }
              OutputStream out = null;
  
              try {
                  out = fconn.openOutputStream();
              } catch (IOException e) {
                  System.out.print("Error opening output stream");
              }
  
              try {
                  out.write(data);
                  out.flush();
              } catch (IOException e) {
                  System.out.print("Error writing to output stream");
              }
  
              try {
                  fconn.close();

                  System.out.print("Error closing file");
              }
      }
  

  Help, please.

  Thanks much for the reply.

  I found the problem, the byte array which I was the analysis was not proper, so I created the image first and after that used the information bytes of that to save the image. Here is the solution.

   public void callback(final String data)
      {
          if (data.startsWith("Exception")) return;  
  
          try
          { 
  
              byte[] dataArray = data.getBytes();
              bitmap = EncodedImage.createEncodedImage(dataArray, 0,
                      dataArray.length);
  
              if(this.width !=0 && this.height !=0){
                  bitmap = ScaleImageToSize(bitmap, this.width,this.height);
              }
              setImage(bitmap);           
  
              if(isWriteImage()){
  
                  System.out.println("Before writing the image");
                  writeFile(bitmap.getData(), Imagedirectory.toString());
                  System.out.println(Imagedirectory);
                  System.out.println("Image written - Operation Successful");
              }
  
          }
          catch (final Exception e){
              System.out.println("Image Creation Failed");
          }
      }
  

  The problem was because I was the array of bytes of the string of variable data analysis. No idea why this caused a problem?

• recover device user agent?

  This may be a bad question but would like advice in the right direction.

  Suppose an application has a built-in browser field. In request HTTP for the browser, the application must add user profile, x-wap-profile agent, accept, accept-charset, etc. in the header. If we want the app to work on different phones, we would like to dynamically detect the user agent of the device profile, x-wap-profile, accept, etc. of the capabilities or properties.  Can use them for the browser field.

  Is there a way to retrieve user profile, x-wap-profile of a device agent?

  Thank you

  Try this one:

  String version = "";
          ApplicationDescriptor[] ad = ApplicationManager.getApplicationManager()
                  .getVisibleApplications();
          for (int i = 0; i < ad.length; i++) {
              if (ad[i].getModuleName().trim().equalsIgnoreCase(
                      "net_rim_bb_ribbon_app")) {
                  version = ad[i].getVersion();
                  break;
              }
          }
  
          return "Blackberry" + DeviceInfo.getDeviceName() + "/" + version
                  + " Profile/" + System.getProperty("microedition.profiles")
                  + " Configuration/"
                  + System.getProperty("microedition.configuration")
                  + " VendorID/" + Branding.getVendorId();
  

• question how to get/use the line separator

  I'm trying to get the line of the system separator and use it in a text that is getting added to a TextField.

  System.getProperty ("line.separator") returns null.

  What is the correct way to do it?

  Here is a code example:

  String newLine = System.getProperty("line.separator");
  String text =   "First line of text." + newLine +
          "Secon line of text." + newLine +
          "Last line of some more text.";
  
  TextField t  = new TextField(TextField.READONLY);
  t.setText(text);
  

  I tried this with the Simulator and on a Pearl 8100.

  I use JDE plugin for Eclipse 1.0.0.50

  BlackBerry component Pack 4.5.0.14.

  2.9.0.52 - Blackberry 8100 smartphone Simulator

  The device software is 4.5.0.110

  Thank you

  If I understand the question, what right do something like "\n"?
