The file InputStream is null

• move the cursor at the beginning of the file (InputStream)

  Hello! I read a file (using InputStream) and necessary move the slider at the beginning of the file (to be able to search inside the file, moving at the beginning and then jump bytes). I'm targeting 4.5 OS. Is it possible to do? Can I reopen it the file? (is it slow? is this a bad idea?)

  Thank you very much!

  Call InputStreamReader.mark (readlimit) in early reading. Then call InputStreamReader.reset () whenever you want to reset the position of the stream of input to its original position, when the brand was called.

• get the Inputstream of the file jasper from a specific path

  Hello

  I use jdev 11.1.1.7.0

  I need to get the InputStream of the file jasper in my application to view the report in PDF format. I do this by following codes:

  
  ServletContext context = getContext();
  InputStream inputstream = context.getResourceAsStream(repPath); //  repPath = "reports/reportName.jasper"
  
  
  
  

  whereas the repPath is the folder that exist in the current application (ViewController\public_html\reports\reportName.jasper)

  but I want to put all in a specific folder as "d:\reports" and all reports call for applications of this path.

  but when I put repPath = "d://reports//reportName.jasper", the variable in the code below inputstream is null

  
  InputStream inputstream = context.getResourceAsStream(repPath); //  repPath = "d://reports/reportName.jasper"
  
  
  
  

  I need to have a specific for all reports path, because some reports can be called from many applications, can someone help me?

  Concerning

  getResourceAsStream() return resources compared to the current ClassLoader.

  You can use something like:

  inputstream = new FileInputStream(repPath);

• Read and write the empty file - InputStream

  Hi all

  I have a problem with the playback of a file.

  This is my code:

  I create my file and put my datas:

  try {
          String filePath = "file:///store/home/user/locations.txt";
      FileConnection filecon =(FileConnection)Connector.open(filePath,Connector. READ_WRITE);
  
      // Always check whether the file or directory exists.
      // Create the file if it doesn't exist.
      if(!filecon.exists()) {
          filecon.create();
      }
  
      OutputStream out = filecon.openOutputStream();
  
      out.write(data.getBytes());
  
      filecon.close();
  
  } catch(IOException ioe) {
  
      Dialog.alert(ioe + "");
  
  }
  

  Then I want to read my data but my inputStream is empty and I don't understand why...

  String filePath = "file:///store/home/user/locations.txt";
  FileConnection filecon = (FileConnection)Connector.open(filePath,Connector. READ_WRITE);
  
  // Always check whether the file or directory exists.
  // Create the file if it doesn't exist.
  if(!filecon.exists()) {
      filecon.create();
  }
  
  InputStream in = filecon.openInputStream();
  InputStreamReader  reader = new InputStreamReader(in);
  
  StringBuffer sb = new StringBuffer();
  
  final char[] buf = new char[1024];
  int len;
  while ((len = reader.read(buf)) > 0) {
      sb.append(buf, 0, len);
  }
  
  data = sb.toString();
  

  Thanks for your help...

  Welcome to the forum.

  Can't see anything obviously wrong.

  I suggest for now you change to use the SD card instead of the store and run in the Simulator with the SD card simulated as a directory.  You can browse the Windows directory and if, in fact, the file is created as expected.

• Validate the file browse point is not null?

  Hello, using APEX 5.0.1. I have a process that needs to run in case a file browse is not null - validation of the PL/SQL Expression. * The file storage type is: BLOB column specified in the attribute of the Source element. for example: P14_STATUS_ID_CURRENT_VALUE = 0 AND: P14_IS_CANCELLED = ' only AND: P14_FILEBROWSE_ITEM IS NOT NULL, even if I download the file, the validation fails! ??? Then I tried this validation, but no result, select FILENAME from wwv_flow_files where name =: p$ _fname and: P14_STATUS_ID_CURRENT_VALUE = 0 AND: P14_IS_CANCELLED = 'n') is this a bug? is there a work around?

  Solved: It should be: dbms_lob.getlength(:P14_FILEBROWSE_ITEM) > 0

  When I try to write a string to a file and then read it again, I get a NullPointerException. When I check the folder that mimicks card SD card on my pc, there is no file created. is the above code ok?

  P.S. I use a simulator of the OS 5.0 and the SD card directory is configured to be somewhere on my desk.

  It is incredibly baroque and inefficient code for a simple job; be happy that you do not claim credit for it.

  A problem may be that the FileConnection in writeFile is not closed. I would rewrite the mess like this (leaving a part of the diagnostic output):

  private void writeFile(String data, String filePath) {  data = data.trim();  OutputStream out = null;  FileConnection conn = null;  try {     conn = (FileConnection) Connector.open(filePath,Connector.READ_WRITE);    if (!conn.exists()) {      conn.create();    }    OutputStream out = conn.openOutputStream();    // it might be advisable to specify an encoding on the next line.    out.write(data.getBytes());  } catch (Exception io) {    test.setText("Exception Thrown from File " + io);  } finally {    if (out != null) try { out.close(); } catch (IOException ignored) {}    if (fconn != null) try { fconn.close(); } catch (IOException ignored) {}  }}
  
  private String readFile(String filePath) {  String result = null;  InputStream input = null;  FileConnection conn = null;  try {    fconn = (FileConnection) Connector.open(filePath, Connector.READ);    if (fconn.exists()) {      input = fconn.openInputStream();      byte[] bytes = IOUtilities.streamToBytes(input);      // it might be advisable to specify an encoding on the next line.      result = new String(bytes);    } else {      System.out.println("File does not exist");    }  } catch (Exception ioe) {    System.out.println("Error: " + ioe.toString());  } finally {    if (input != null) try { input.close(); } catch (IOException ignored) {}    if (fconn != null) try { fconn.close(); } catch (IOException ignored) {}  }  return result;}
  

• LaserJet MFP M125nw Pro: #2 cannot install LaserJet MFP M125nw Pro because of the error "the system cannot find the file specified."

  Hello

  I struggled in the last 2 days to install my new all in one Pro LaserJet MFP M125nw. I tried almost all the stuff Google and this community offered under the heading "the system cannot find specified file", without success. My frustration is huge because I'm not really a novice when it comes to solve similar problems.

  Here is what I do and what is happening:

  I downloaded the latest version of the complete software for XP HP offers through their Web site. I tried to install the drivers through the install wizzard, then manually (used for the files in the folder 7ZXXX in the directrory temp) but no matter what I do, I get the same error again and again. In fact XP recognizes the printer and the scanner, it installs even drivers for the scanner and it works but after maybe 50 attempts in different ways, XP couldn't install the printer driver.

  Here are a few screenshots:

• The macro was interrupted because of an error, but the file remains open.

  I have a file that is opened by a macro Excel (VBA).  The macro was interrupted because of an error, but the file remains open.  I can't find any way to close.  The file is located on a server, not my hard drive.

• Attach the file to your e-mail via mailto + invocation framework

  I am tryng to attach a file to an e-mail message using the mailto syntax.

  The email app is opened by the framework of the call

  MailSubject = "Test"
  MailBody = "Hello!";
  
  // create handler invocation
  navigator_invoke_invocation_t *invoke = NULL;
  navigator_invoke_invocation_create(&invoke);
  
  // setting the browser as target

  // invoke the target
  navigator_invoke_invocation_send(invoke);
  
  // clean up resources
  navigator_invoke_invocation_destroy(invoke);
  

  I tried to delete file:/// and put / alone but doesn't either.
  The file is located in the shared folder and I know is the only way to attach a file to an email.

  There are a few examples, but none of them have pre-compiled field such cc + object + body + attachments together.

  Can someone help me?

  Thank you

  I went from Json to QVariantMap and no, it works without problem. Here is the code:

      bb::system::InvokeManager InvokeManager;
      bb::system::InvokeRequest InvokeRequest;
  
      QVariantMap EmailData;
      QVariantMap EmailDataWrapper;
  
      EmailData["to"] = "[email protected]";
      EmailData["cc"] = "[email protected]";
      EmailData["subject"] = "MailSubject";
      EmailData["body"] = "MailBody";
      EmailData["attachment"] =  "/accounts/1000/shared/print/file";
  
      EmailDataWrapper["data"] = EmailData;
  
      InvokeRequest.setTarget("sys.pim.uib.email.hybridcomposer");
      InvokeRequest.setAction("bb.action.COMPOSE");
      InvokeRequest.setMimeType("message/rfc822");
      InvokeRequest.setData(bb::PpsObject::encode(EmailDataWrapper , &bool_result) );
  
      InvokeManager.invoke(InvokeRequest);
  

• Problem with the file opened in the application via InvokeRequest

  Hello

  my application opens the file and reads its binary content. I have a small problem to open a file from a navigation or an attachment.

  But first here's how my app works. I have a signal/slot-connection in my applicationUI constructor:

  ApplicationUI::ApplicationUI(bb::cascades::Application *app) : QObject(app), m_invokeManager(new bb::system::InvokeManager(this)) {
  
    bool ok;
  
    // Since the variable is not used in the app, this is added to avoid a
    // compiler warning.
    Q_UNUSED(ok);
  
    ok = QObject::connect(m_invokeManager, SIGNAL(invoked(const bb::system::InvokeRequest&)), this, SLOT(handleInvoke(const bb::system::InvokeRequest&)));
  
  }
  

  So if the user clicks on a file it can open in the following C++ function:

  void ApplicationUI::handleInvoke(const bb::system::InvokeRequest& request) {
  
      QString workingDir = QDir::currentPath();
  
  // Initiate the appropriate target based on the invoke.target-key
      if (request.target() == "com.myapp.card.previewer") {
  
          m_uri = request.uri().toString();
  
          QString FileToOpen = m_uri.replace(QString("file://"), QString(""));
  
          bb::cascades::Page* PageToOpen = ApplicationUI::doLoadPageDetails(FileToOpen);
  
          if (PageToOpen != NULL) {
              initPreviewerUI();
          } else {
              ShowToast("FEHLER! Seite kann nicht geladen werden");
          }
      }
  }
  

  The doLoadPageDetails () - function creates a page and filled with binary content of reading a file. If the file contains errors or is corrupted an exception is thrown.

  And here is my problem. When I opened a file corrupted first the screen becomes darker before opening the app. The I get error messages, exactly as I want. But the screen stays dark. I can't take another navigation element. Also, I can't use the back button. The only solution is to wipe the screen and then use the active frame to close the filebrowser and reopen it.

  That I can't use it with attachments to emails. When I open on and the screen is dark, I can't close the view for emails. So to see the mails again I have to restart the BB decive.

  I'm not fluent in English, but I hope you understand my problem. Is it possible to cancel the invokeRequest when the file is corrupted? Or what can I do here?

  Well, the solution was to use a Toast message but the dialog box. Because that prevents the application and I can't and shows just the message, with the button on this dialog box, I cannot tell the app to close.

• Detects the MIME type of the file

• Copy the file in "res" to the file system

  Hello

  I am trying to copy a file from my .cod file in the file system, so I can crush it etc. However, I can't get the file to write. This is the code that I use in this time, I found it while searching for the community.

  try {}
  FileConnection fc = Connector.open("file:///store/home/holidays.xml") (FileConnection);
  If (! fc.exists ()) {}
  FC. Create();
  OutputStream os = fc.openOutputStream ();
  InputStream is = getClass().getResourceAsStream("/xml/holidays.xml");
  Byte [] buf = new byte [1024];
  int len = 0;
  While ((len = is.read (buf)) > 0) {}
  OS. Write (buf, 0, len);
  }
  is. Close();
  OS. Close();
  Add (new LabelField ("" wrote leader. "'));
  }
  } catch (IOException e) {}
  e.printStackTrace ();
  }

  It is in the constructor of the form. When I run the app, I do not get "the file was written., just a white screen. Any suggestions on what I am doing wrong?

  Thank you in advance,

  Ben

  Thanks for the tips,

  I finally understood what was going on; something about reading the xml/holidays.xml file didn't work at all. In the end, I read a holidays.txt file in an xml file in the file system. This isn't a good solution, but it works fine now.

  Thank you

• New line characters in the file writing

  I use the following function to write text in the file

  public void DebugLog (String strTxt)
  {
  System.Err.println (strTxt);
  System.Err.println("\r\n");
     
  Try
  {
  String iFileName = "file:///SDCard/BlackBerry/pictures/Debug.log";
  FileConnection fileConn = (FileConnection) Connector.open (iFileName, Connector.READ_WRITE);
  If (fileConn! = null)
  {
  If (! fileConn.Exists ())
  fileConn.create ();
                 
  OutputStream os = fileConn.openOutputStream (fileConn.fileSize ());
  DataOutputStream back = new DataOutputStream (os);
  dos.writeChars (strTxt);
  back. Close();
  fileConn.close ();
  }
  }
  catch (Exception ex)
  {
  }
  }

  The function above very well written text to file. But when the txt contains \r\n which is not reflected in the line break in the file. He appears just as \r\n in the file.

  What changes I need to make sure that the line break is refrlected correctly in the file. I need to convert any other sequence of bytes using a Unicode conversion, \r\n

  try to use

  dos.writeUTF

• How to increase the size of the file

  My application creates .amr files of 0 KB after completing the recording of the voice. How can I increase the size of the file.

  I think I am, but I write my code if you could help me.

  • This is in fact the problem is that it is not written in my .amr file if it is their creation

  whenever I call someone.

  • Furthermore it is also telling me that 'myappname' trying to record media.

  So confirmation registration takes place

  However why write records into mu .amr files intrigues me

• Open the file server .txt and analysis

  I'm trying to open a .txt on my server and analyze the content, the content is a version number and a link.

  I have something like this

  ContentConnection updateConnection = null;
  
  try {
              updateConnection = (ContentConnection)             Connector.open(updateUrl);
  
            .....
  
           ......
  
     } catch (ConnectionNotFoundException e){
              e.printStackTrace();
          } catch (IOException e){
              e.printStackTrace();
          } catch  (IllegalArgumentException e){
              e.printStackTrace();
          }
  

  I'm capturing the IOException exception. Is it possible to open a txt file and analyzed. I can change the format of the file to something else if necessary. I thought that keeping it as a txt should be ok because I have to analyze only 2 pieces of information about him.

  Thank you.

  You can use

  http://www.BlackBerry.com/developers/docs/6.0.0api/NET/rim/device/API/IO/IOUtilities.html#streamToBy...

  to retrieve the file.

  create a string from the byte array and analyze its contents.
