Opening existing file for writing

Hey how do I open an existing file for writing. For example I want to just add one more line to a file after it has been closed but I don't have the reference to the FileWriter / BufferedWriter object. So I have to tell the directory maybe but how do I open it and start writing to it at the end.
Thanks.

You just create a new File Object<br>
File f = new File("c:/foo.txt");<br><br>
Then you can read or write to that file with FileReader or FileWriter<br>
FileWriter fw = new FileWriter(f);<br>
fw.write();<br><br>
If you want to append sth. to a file I would recommend RandoAccessFile<br>
RandomAccesFile raf = new RandomAccesFile(f, "rw")<br>
Now you can get the length of the file and set the pointer to the end <br>
raf.seek(raf.length());

  • "Attempt to open locked file for writing, Result Code = -54" when importing

    I get this error box when importing audio files into a logic session over my network.
    +Attempt to open locked file for writing+
    +Result Code = -54+
    The finder is capable of copying the files over to the local machine, at which point I can successfully import them into my local logic session, but Logic is incapable of doing the same. Strange and annoying.

  • FileNotFoundException thrown when opening a file for writing from EJB

    Hi,
    I know it is against EJB rules that access file IO from EJB. However we have a legacy system to working with and we need to generate a text file on file system.
    Weblogic (we are using 10.3) allows open a file for read from EJB. When we tried to open a writer like below:
    BufferedWriter writer = new BufferedWriter( new FileWriter(fileName, false));
    FileNotFoundException was thrown from the native method of open. The fileName is an absolute path and permission is properly set. The same piece of code can execute correctly in a test application with same filename.
    Does anyone know how to achieve this or whether Weblogic just forbids this kind of output access?

    Sorry guys. Just double-checked the source code and found out a bug produced wrong filename, the filename was surrounded by "", so FileNotFoundException is a correct result.
    Weblogic does allow read/write external file.

  • Can't open a file for writing in the ProgramData folder

    Hi,
    I have a simpe text file in the ProgramData directory that I need both to read and write to.
    SHGetFolderPath(0, CSIDL_COMMON_APPDATA, 0, SHGFP_TYPE_CURRENT, userpath);
    PathAppend (userpath, TEXT("Testfolder/gnsh.dat")); licensefile = _wfopen(userpath, L"r+"); 
    However, the only way I have been able to open the file both in read and write modus, is to run the program as an administrator. But this is not a practical solution. The question is then if there is a way  to open this file in both moduses when running
    the program in the normal way, not as an administrator.
    Thanks in advance.

    Hi,
    Thank you for youre answer, that was very useful. It helped me find the solution. The file I wanted to edit was downloaded with Inno Script Studio, which by installation changed the attributes of the file to none writable. So simple by setting a parameter
    in this scripture I was given write access.
    Best regards

  • Cannot open file for writing...

    I keep getting this error...
    Cannot open "filename" file for writing. Please check the output filename and file permissions (if it already exists) and then try again.
    Not sure what is going wrong here. I have scoured the web and can't find a solution.
    Running CS5 on a Mac.
    Any help is appreciated!!

    This might indicate a problem in AME CS5, but we'll need more information about the clip--and possibly a copy of it--before we can make that judgment.
    If the clip plays on Computer X but not on Computer Y, that could indicate that X has a certain codec that's missing on Y.
    What codec is the clip? What's the extension of the filename (which equates roughly to the type of wrapper)?
    What are the origins of the clip? (e.g., is it straight off of a camera? or was it encoded by another program?)
    Do you have AME 5.0.1 installed on both computers?

  • Error opening file for writing when installing

    I cannot install Flash on my Vista X64. I have tried running
    the downloadable install and the online install. Any time I try to
    run the install I get "error opening file for writing" when trying
    to write C:\Windows\SysWOW64\Macromed\Flash\Flash9d.ocx.
    I have uninstalled Fash first (it never worked anyway) and I
    have rebooted. I even tried rebooting in Safe Mode but no matter
    what I try, I cannot remove the existing Flash9d.ocx and installing
    will not overwrite the existing file.
    Even after uninstalling Flash and rebooting to safe mode,
    Windows reports that flash9d.ocx is in use. So why is the file in
    use after uninstalling?
    Any help is appreciated.
    Dale

    Well, I finally figured out the problem with mine today. Of
    course, I'd still like to know what nefarious purpose might be
    involved with the Flash activeX file being loaded in memory even
    after uninstall and reboot such that it cannot be removed from my
    PC even in Safe Mode.
    At least I got Flash working. I discovered that Flash was
    disabled in IE.
    In IE, go to Tools->Options->Programs and then Manage
    Add-Ons. In my case, the ShockWave Flash Object was set to
    disabled. I changed it to Enabled and I was able to install and use
    Flash properly. Now I am just not sure I want to.
    With the questionable practices of using the ActiveX control
    even after uninstall, and making the file un-removable, along with
    the extremely (in my opinion) dishonest practice of installing
    Google Toolbar with Flash, I am hoping that Microsoft's Silverlight
    puts Flash out of the market - and I'm no huge fan of Microsoft
    either. With the new practices from Adobe, they are, in my opinion,
    no better than any other spyware and malware purveyor on the market
    - right up there with Napster and the dozens of follow-on products
    that tricked users into installing unwanted software.

  • Vi error on nfs mount; E212: Can't open file for writing

    Hi all,
    I've setup a umask of 0 for testing on both NFS client (Centos 5.2) and NFS server (OSX 10.5.5 server).
    I can create files as one user and edit/save out as another user w/o issue when directly logged into the server via ARD.
    However, when I attempt the same from an NFS mount on a client machine, even as root I get the following error using vi;
    "file" E212: Can't open file for writing
    Looking at the system.log file on the server, I see;
    kernel[0]: add_fsevent: no name hard-link! dropping the event. (event 2 vp == 0xa5db510 (-UNKNOWN-FILE)).
    This baffles me. My umask is 0 meaning files I create and attempt to edit as other users are 777, but I cannot save out edits unless I do a wq! in vi. At that point, the owner of the file changes to whomever did the vi.
    This isn't just a vi issue as it happens using any editor, but I like to use vi.
    Any help is greatly appreciated. Hey, beer is on me!

    Hi all,
    Thanks for the replies
    I've narrowed it down to a Centos client issue.
    Everything works fine using other Linux based OS's as clients.
    Since we have such a huge investment in Centos, I must figure out a workaround. Apple support wasn't much help as usual however they were very nice.
    There usual response is "its unsupported".
    If Apple really wants to play in the enterprise of business space, they really need to change there philosophy. I mean telling me that I shouldn't mount home directories via NFS is completely rediculus.
    What am I supposed to use then, Samba of AFP? No, I don't think so. No offense to Microsoft but why would I use a Windows based file sharing protocol to mount network shares in a Nix env???

  • Cannot download Flash Player 10 due to - Error opening file for writing: Flash10d.ocx

    Hello all,
    I am having difficulty installing Flash Player 10. I open it up, and only 10% of the download bar finishes before I get the message:
    "Error opening file for writing:
    C:\Windows\system32\Macromed\Flash\Flash10d.ocx"
    I am running Windows Vista with Internet Explorer, although I'm not 100% sure which version of IE it is and haven't found out how to check. I have McAfee for security, but I have already tried disabling the Firewall with no success.
    My computer is new, so there's a chance that it already has Flash Player 10 on it since it belonged to someone else before it came to me, but I don't know how to check that either.
    Any suggestions?
    Thanks!

    Let me clarify:
    I have already tried disabling the firewall and running the installer again, but it didn't work.

  • Error Opening File for Writing

    I have a laptop running on Windows XP and I was having a really hard time running applications on Face Book. I kept getting a message to "kill pages" or "wait" for the program to respond. Most times it would eventually automatically "kill pages" and I am unable to use those apps. It's not only on Face Book either; some other pages will not run due to this problem. So I visited the Adobe web site and it said my version was out of date and that I needed to download the latest version. I did and now I am getting the error unable to open file for writing. (C:\WINDOWS\system32\Adobe\Shockwave\SwHelper_1166636.exe) I don't know if that matters or not.
    I cannot download the latest version; I don't know what other information I can give about the laptop; I am now getting the message "A plug-in (Shockwave) isn't responding". Please help if you can.
    Thank you for your time and help,

    That is actually Shockwave Player.
    So does this FB app actually require Flash Player or Shockwave Player?
    Get Flash Player from http://get.adobe.com/flashplayer/

    From the error message above,  please check the permission for file writing , it seems that this issue is related to access permission.

  • Cant open project using "Open Existing File"

    Using GB 11, if I try to open an existing .band project with the Open Existing File button, or from the File/Open menu option from within GB, the "Open" button is grayed out, as are all of the other buttons on the screen. On the other hand, if I select the project from GBs recent projects section, or if from Finder, I select Open with GarageBand from the File menu, I can open the project. I've checked that I have permissions on the Garageband folder and the files within. Does anyone know how to fix this? Thanks.

  • Can't open '/dev/rdisk1' for writing (Resource busy)

    I got a Macbook Pro, install win7 on boot camp. When I wanted to resinstall win7, I accidently click on Recover button and it deleted all my partitions and become one, which run Mac OS. I tried to recover my data partition. On google, I found some guy do it with 'pdisk' command. I followed steps but when I tried to use pdisk:
    sudo pdisk /dev/rdisk0
    and use command 'i':
    i got a message: can't open '/dev/rdisk0' for writing (Resource busy)
    So I borrowed a Mac, connected it with my Macbook through FireWire, and set my Mac in 'Target Disk Mode' and use pdisk again:
    sudo pdisk /dev/rdisk1
    when i use command 'i', i still got the message:
    can't open '/dev/rdisk1' for writing (Resource busy).
    Can anyone know what is this problem? Do I need to extract my hard disk from my Mac?
    Please tell me about it!

  • I need to make a pdf document, made in photoshop, 'page turn' and then add it to my website. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    I need to make a pdf document, already made in photoshop, 'page turn' and then add it to my website as an e-brochure. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    Hello waitingone,
    please try this (all terms are translated from my German programs to my best knowledge):
    1. Did the creator of the pdf file enable the import options?
    2. See import options: choose an other visibility option for your layer.
    3. Let you show the import options and click into one with a black background and try these out (often a gray is selected).
    4. See trimming: try the different modes there. Often works: "Media".
    5. Is the pdf file (eg from Word) correctly created?
    6. Is the PDF file protected? >>> no import possible.
    7. If that does not help, store the pdf file in Acrobat, repair possible errors, run the PDF Optimizer before placing in InDesign.
    Good luck!
