How to create/read/write textfiles in a jar archive?

Hi!
I would like to know how to create, read and write text file in a jar file?
//Marcus

You want to update "files" that are inside a jar archive? You can't. At least not very easily; to modify a file you need to create a new version of the jar, copy over everything else, and add the new version of that file. Look for a different design that doesn't require updating a jar.

    Hello,
    This should be asked in the ASP.Net MVC forum on

    As Microsoft's ASP.Net forums are on a different platform, we cannot move the question for you.

    Hi,
    Please try to setting Folder Permissions on Web Publish, and then deploy it with Web Deploy, as far as I know, if we do that, Web Deploy will use the SetAcl operation to change permissions. Please have a look at the article below.

  • How do I read/write many matrices through TCP server?

    I'm trying to modify the simple data client and the simple data server program in example in LabVIEW6i. How do I send a 2 dimension nummeric matrix? and also how do I send many numeric matrices at a time?

    The problem here is that at the receiving end, one cannot know how many
    bytes to read before unflattenning into the datatype.
    A method that works for *any* datatype (and any data transfer mechanism):
    Flatten the data to string.
    Flatten again the string to string; this adds a string lenght (U32) header
    to the string.
    Send the string.
    When receiving data, first read 4 bytes and convert to U32.
    Read this number of bytes.
    Typecast the string to the expected datatype.

  • How to programmatically read/write the range of a fieldpoint AI channel using LV

    Is there a way to programmatically read/write the range of a fieldpoint AI channel using LV ? The example on NI site only permit you to have the name of the device and channels, not the actual set of the range of measure. Anybody has a VI (LV5.1 please)to share?
    Thank you very much

    If you are using the FieldPoint VI's (Open, Create Tag, Read, Write, Advise), you do not have the ability to change the range of a channel. If you have a FP-1000 or FP-1001, you can use the Optomux commands as described in the FP-1000/1001 Programmers Reference Manual (FieldPoint Optomux VI's are available at ftp://ftp.ni.com/support/fieldpoint/LVFPOpto/ ).
    Alternatively, if you have an ethernet network module and LabVIEW 6i or later, you can use the ethernet configuration VI's that ship with FieldPoint Explorer 3.0.1.

  • HT1549 How do I read write to an external drive?  I am under admin account and cannot read write to any folder on the external drive.

    I have a Mac Mini with Mavericks installed, as well as a PC running Windows 7.  I want to be able to read write from both computers to an external drive on the Mac.  I created 2 folders on the drive and named them Movies, and TV Shows.  The content of those folders are the respective files. I set up both folders to be shared on the Mac under system preferences, and then mapped the drives on the PC.  I also created a user account with admin privileges on the mac that matched my PC.   I then copied a Music folder to the root drive instead of using external, and set up sharing as well.  File Sharing is selected for all three folders, however the music folder is the only one which allows me to change the permissions to allow read write to everyone, or to create individual user accounts to connect with read write permissions.  The options to add users or change permissions are simply grayed out for the two folders on the external drive, so not only can I not write from my PC, but I can’t even do it on the Mac with the administrative user logged in. The folder on the root drive is fine but I cannot make any changes to the external drive at all.  Get info for any folder on drive shows read only.  SMB and AFP are selected for all folders under options.  I can access all three folders from PC, but can only add files to the Music folder. I cannot do anything from either computer to the folders on the external drive.

    Try Applications/Utilities/Disk Utility - select the drive and run Repair Disk.

  • How to create read only disk image?

    I used to be able to create read-only encrypted disk images with Disk Utility in Mac OS 10.4.x (Tiger). In the Leopard version (10.5.7) of Disk Utility, the 'read only' option seems to be gone (but I can still do encryption). Does anyone know how this can be done?

    A blank empty read only disk image has never been possible. If it's read-only, it cannot be modified, and so it would be blank and empty forever. Not much point in that.
    If you want read-only and encryption on your finished disk image, you'll have to put your files into a folder, and then do File -> New -> Disk image from folder.

  • Macbook Pro 1.1 how to improve read/write speed

    Hello,
    I am looking to improve the read/write performance of a 2006 2.16 Intel Core Duo Macbook Pro with 2gb RAM (the max), that I use on a specific job in a specific workflow.
    In the workflow there are three retouchers using three different MBPs and transferring files via Ethernet network to a fourth MBP (the one in question) which is used as a dropbox, if you like.
    So the MBP in question has no applications running. Files are saved to it and opened from it and saved back to it.
    How can I improve read/write speed on this MBP under these conditions?
    Would installing an SSD be the answer? Or is it really a processor issue and there's nothing to be done? I figure RAM doesn't really come into it, but in any case 2GB is the max this model can accept.
    Many thanks in advance.

    An SSD would definitely improve read/write speed. However, depending on capacity needed, are you sure you want to sink the money into this machine? Start here:

  • How to edit (read/write) an external hard drive that is attached to a router

    Hi everyone.
    I have Macbook Air (2013) with OSX 10.9 Maverics, and Netgear WNDR4500 router with WD external hard drive attached to it. My problem is that I don’t have writing permissions. When I’m trying to change something in the hard drive, it says “The operation can’t be completed, because you don’t have necessary permission”. Under Get info / Sharing & Permissions, it just says “You have custom access”, and there is no option to change privileges to “Read & Write”.
    I would appreciate if anyone could help me with this.
    Thanks!

    I don't use TM, but as far as I know, the only way it will work wirelessly is with a Time Capsule. Check the info here:
    http://pondini.org/TM/2.html
    which is from one of the subheadings here:
    http://pondini.org/TM/FAQ.html
    I would guess that you'd be able to write to the drive once you have it attached via a cable (FW, USB, etc) to your Mac (not your router).
