Permissions in Java

I was reading up on file permissions in java at http://java.sun.com/developer/onlineTraining/Programming/JDCBook/appA.html
I would like to know whether these permissions are for use only within Java or do they apply externally aswell.
I mean if I dont allow write permission in my program and my program is currently running, then can the user still write to the file by opening it outside normally?
Thanks.

Note: This thread was originally posted in the [Java Media Framework|http://forums.sun.com/forum.jspa?forumID=28] forum, but moved to this forum for closer topic alignment.

  • File access Permissions in Java

    when the user select the file chooser button and browse through the directory in the local file system. If the user chooses any folder and that folder has readOnly access permission then the user can't copy the file into that folder as it has only Read access. So Please tell me how to give file and drive permissions in java on windows.

    File.setReadable() and friends, but "The operation will fail if the user does not have permission to change the access permissions of this abstract pathname." Check the return code.

  • Granting permissions for JAVA STORED PROCS

    If I imported a java class file as user test and created a stored proc, how can I grant permissions to all the users in the DB? Do I have to grant permissions on JAVA CLASS itself when I load it or Do I have to grant permissions on the Stored proc or Both?
    Any help will be greatly appreciated.

    Note: I can manually add the file with the command -
    loadjava -v -user user/password@sid sqljdbc.jar (pg 261 in Oracle Database Programming using Java and Web Services by Kuassi Mensah)
    Which is what I have done to get this to work. But the question still stands - How do I get the sqljdbc.jar file to be loaded when deployed using the deployment descriptor?

  • File permissions in Java

    Hi all,
    I'm converting a python script to Java.
    The script creates a directory with special file permissions, as seen below:
    os.makedirs(options.file, 0777)
    ..Is there an equivalent way to set file permissions in Java (and would I need to bother what that..)?
    /Best regards, H�kan Jacobsson - System developer in Sweden

    Is there an equivalent way to set file permissions in JavaNot really. The File class allows you to set some permissions, but I don't think it lets you set the execute bit.
    and would I need to bother what thatDepends entirely on why the original python programmer selected those options.

  • Messed up computer (10.9.4) after migration to SSD - permissions or java problem?

    thanks in advance for reading!  I have a doozy:  I moved my hdd to my optibay and installed a new SSD into my main hdd bay (mbp late 2011)
    transferred data from hdd to ssd using superduper
    so the ssd is now a clone of the old hdd (and in the same place as the old hdd) and the ssd is the startup
    BUT
    seems permissions are wonky?
    not sure what it is.  possibly java is a problem -- maybe via permissions?
    here's the symptoms:
    browsers/finder work great (faster with ssd)
    but MANY apps just wont load or are wonky.
    bluestacks won't load-- wont even get to the "loading" animation...  (have re-installed numerous times)
    metasearch on vuze won't work -- I see it for 7 seconds and then it vanishes.
    other apps wont load -- the problem seems to be java related maybe?  I'm not clear.
    steps I've taken to resolve:
    (all did nothin)
    re-installed every app that wasn't working (ug!  endless!  appcleaner etc!  hard to say how far they were uninstalled but seemed pretty thorough)
    re-installed OSX 10.9.4
    repaired permissions in a few ways on ssd
    even "Reset Home Folder permissions and ACLs"  via rebooting with cmnd+r
    downgraded to java 6 (did nothin) then back up to java 7 (nothin)
    erased all the java caches etc I could find
    now I'm not really sure WHAT is going on here -- but my suspicion is that there's something funny about the superduper migration and permissions  (everything was working when I upgraded to 10.9 a month ago)
    I noticed: when I open a lot of folders, like utilities etc, they're read-only.  huh?  I don't think that was true, before.
    to fix this I made the possible mistake of GetInfo/giving read-write privileges to everyone and "applied to enclosed items"
    maybe that was dumb?
    either way, after rebooting and repairing permissions, it seems the read-only structure of much of the new ssd is back
    (I'm logged in as my main account as always -- is this not root? I'm never clear on root stuff...) (with mavericks, before the migration, I was able to run all these apps fine.  but none of these odd "read-only" icons were showing up in my folders)
    so maybe bad permissions -- or bad java -- is the reason apps won't connect to the internet?  sometimes they crash when running animations.
    ANY help would be so appreciated!  already wasted many full days on this!  ack!

    >This how-to does not actually help you to create a true fusion drive. What you are actually doing is creating one volume group out of the SSD and the harddrive and presenting that to the OS as one or more logical volumes. This is a very different sort of beast than a fusion drive. With this setup, If the SSD is the first drive in the volume group, new files will be written to the SSD until it fills up and then files will be written to the harddrive. This explains why one commenter witnessed, using iostat, new files being written to the harddrive rather than the SSD and others said it started off fast and then got slower later on. If you don't want to buy a fusion drive, but do want fast boot times and fast loading of programs, I would suggest using these as two independent formatted drives. Install the OS and programs on the SSD and store the majority of your files on the harddrive.
    I think I'm happy with having the SSD handling the OS etc
    and my HDD doing media
    wud be nice, however if when I put stuff from the HDD into the trash it doesn’t ask to delete immediately the way it would if I was on a wifi network with another volume (what IS that about...?)  these volumes are connected so directly, why cant I throw something in the .trash from the optibay-HDD and let it sit there till I'm sure to erase it?  :/
    This is a Fusion Drive by definition. A Fusion drive is also a Logical Volume and a CoreStorage volume. ( Please see this as well - http://forums.macrumors.com/showthread.php?t=1530110 ). If you run the same commands on an Apple-provided "Fusion" drive, you will see similar output.

  • Repairing Permissions after Java Update

    I installed the latest Java update as prompted by Software Update. Then I repaired permissions and am getting the same lengthy log every time even though it states "Permissions repair complete":
    "Group differs on "Library/Application Support/iLifeMediaBrowser/Plug-Ins/iLMBiPhotoPlugin.ilmbplugin/Contents/Resourc es/da.lproj", should be 80, group is 0.
    Repaired.....etc, etc."
    There are at least 25 - 30 of those; plus there are quite a few on the Java VM framework.
    Is this anything to worry about?

    Yes, everybody's getting them. As long as the repair states "Permissions repair complete", you're good to go.

  • Changing file permissions in java

    Hi..
    I am creating log files using file handler class.They are created with some permissions in linux. Now I want to change the permissions of the those log files.
    I run this java code only once..so it should modify the permissions of the existing log files and the permissions of the new files getting created as well.
    Could u any one shed some light on it...
    Thanks in advance..

    Kiran,
    There are several ways to do this. I guess the easiest would be to change the "umask" of the (linux) user who is launching OC4J -- that way, any file created by that user will have the required permissions. Isn't that better than creating the files with the wrong permissions (in the first place) and them trying to change them afterward? (Or have I misunderstood your question?)
    Anyway, I fail to see how this is connected to OC4J?
    Good Luck,
    Avi.

  • Permissions to "java.io.tmpdir"

    Hello!
    I am getting an error on startup of my simple JSC2 application. It not starts, gets a error for JSP page (see www.taligent.com.br/Page1.jsp).
    The support of my host provider says that I cannot use java.io.tmpdir folder, due to a shared environment. See what he says:
    It looks like the problem is with an error that is occurring during the start-up of your context, which is preventing the context from being activated. The permissions error is "java.util.PropertyPermission java.io.tmpdir read"; since this is a shared environment you cannot access the "java.io.tmpdir" folder, although this should not be a problem, and you can configure your application to use a different folder under your file system. To speed this up I have already created the folder for you, named "/var/www/temp", with write access for your context. When specifying the folder path within your application please be sure to use the full path, which is "/home/virtual/site19/fst/var/www/temp".
    So, where I can change this in JSC2 to make a compatible application with my hosted shared tomcat?

    You could try workdir arugment in web.xml context descriptor to define your workDir
    http://tomcat.apache.org/tomcat-5.5-doc/config/context.html

  • Problems with Disc Permissions for Java Virtual Machine

    hi,
    My machine (10.6.6) crashed. I had the spinning beach ball.
    Force Quit and On/Off did nothing.
    I needed to unplug and remove the battery to restart.
    After that, I did Repair Disk Permissions.
    It finds a bunch of things for Java Virtual Machine/1.6.0/jdk
    It says it fixes it.
    But if I reboot and and run Repair Disk Permissions again,
    it still finds the same problems.
    How do I get it fixed?

    Hi,
    these permission errors are normal. There's nothing to be worried about. If you search around (you did search around first, right?) you'll find that most, if not all, Snow Leopard users see these messages.

  • Setting file permissions in java

    Hi,
    Iam uploading a file to a folder which exists on a unix machine.
    Iam using struts FormFile to upload a file.
    After uploading a file i observed that the permissions for the uploaded file are like this
    rw_ r-- r--
    for the owner it give read and write and for the rest only read permission.
    But i want read and write permissions for all the three.
    is there any way from java to change the permissions for a file on UNIX machine while uploading?
    I know RunTime.exec() . But they mentioned that it runs as a separate process instead of a thread.
    Can i use that? is there any problem by using RunTime..
    is there any other way to set permissions for file in java?

    You will have to use Runtime.exec(). Java doesn't allow you to set file permissions this specifically.

  • HT203176 my computer hangs frequently - rolling beach ball - apparently some endless loops - I have repaired the permissions countless times but the problem continues - the faulty permissions include java virtual machine and language libraries

    I get the rolling beach ball frequently when using a browser -I have repaired the permissions a number of times - each time I do this - the same issues show up-  language libraries, java virtual machine etc - after a restart the btowser works for awhile and then hangs again - i trashed both Chrome and Firefox and am now using Safari and Opera - neither of which work very fast and I still get a frozen screen - rolling beach ball - have to force quit.On the activity monitor it shows that the  browser I am using has several hangs.
    Aside from reinstalling everything - is  there a fix for this? 

    Those Permissions errrors will keep appearing. They are not errors; ignore them. Your problem has nothing to do with Permissions repair. Many possible causes, one of which may be A-V. Do you have any A-V installed?
    What does Disk Utility show for SMART Status for the drive? Verify the Disk.
    Open Activity Monitor>CPU tab. Anything hogging the CPU when the slowdowns occur? Switch to the Memory tab. What does it show for free and inactive? Also, Page ins, Page outs and Swap used?'
    How many applications open concurrently when this happens?
    How much drive free space? You should maintain at least around 20-30GB.

  • Open file dialog in java apps causes segmentation fault

  • Can't get Java (JRE8U45) to work on IE11

    Hello, I must be missing something simple here but I have been unable to get any page requiring Java to load in Internet Explorer 11, at least on machines running Windows 7. I have tried it with multiple machines, all fully patched and up to date and can
    not even get the Java Version Check page to load, I am just told that Java is disabled or not installed. The latest version of chrome, will load Java pages on the same machines (after enabling the npapi plugin flag).
    IE tells me the plugins are incompatible if I run it normally, if I right click it and run it as an Administrator, then it allows me to enable the plugins but the Java Version Check site still tells me they are not installed. I have tried running the version
    check in compatibility mode as well as regular mode and in either case I can just not get these plugins to work.
    Can anyone point me in the direction of what I might be missing here?
