How to get the path of the cache directory ?

Hi everyone,
I need to get the path of the cache directory to copy files into it (these files are security files that are necessary to encrypt data).
Maybe there is a jnlp.jar to have object that implements a method getCachePath() ? But I can't find it.
Any ideas ?. thanks.

you can find the cache location by finding the location of the jar file you are running from:
URL resource =
this.getClass().getClassLoader().getResource("testResource");
if (resource != null) {
String s = resource.toString();
if (s.startsWith("jar:")) {
int index = s.indexOf("!");
if (index > 4) {
String fileurl = s.substring(4,index);
if (fileurl.startswith("file:")) {
String path = fileurl.substring(5);
// now path is the path to the jar file in the cache containing the resource

  • How to get file path in the form \\filer01\dir\index.htm

    Hi,
    after selecting a file using the FileChooser dialog, i would like to convert the file path like "H:\index.htm" into a form like "\\filer01\dir\index.htm".
    On my system, the logical device name H:\ is mapped to a directory on a file server "filer01".
    Is there any possibility to do this conversion?
    Thanks in advance.

    hi,
    i dont think java has a way of figuring out the actual mappings for a drive, you can retrive all drives that are present using the following code
    File [] roots = File.listRoots();
    then you could just iterate through the roots some of which may be mapped (but you cant figure out which is mapped and which is not).
    So i guess the best way to do it is to have a Properties file with key,value mappings. for eg
    h:\\, \\file01\dir\..
    and then read the value from the Properties file, now if you want this for accessing a resource across the network you dont require to get the actual mapping, you can still use the mapped drive as you would use a unmapped drive.
    hope this helpz

    When a file is uploaded, the file name is also submitted. The path of the file is available only to the machine within the Local Machine security zone. The value property returns only the file name to machines outside the Local Machine security zone. See About URL Security Zones for more information on security zones.
    i need to know on how to get the compelete path /directory of the filename
    using <input type="file"> tag You can't. Its a security thing.
    is there any other way to get an input file from a local host aside from <input type="file"> tag?No. Not using just html.
    You could always go into activex components, but thats different again.

  • How to get the path of the image stored in sap??

    Hi All
    The problem is
    While making an entry in standard there is a field called documents through which we attach our images in sap.
    How to get the path of the image stored with the corresponding order so that the image can be displayed while we are creating a report.
    I know how to upload the image while creating a report using docking control.
    I am not able to get the path of the image stored...
    Please Help
    Thanks in advance..
    Pooja

    I am not aware of exactly which tables are used for storing the attached doc. details, but we have worked in the similar requiremnent.
    What you can do is .... before uploading the image to any order, try swich on the SQL trace ST05 and after upload switch off.
    The log will display what are the tables involved while storing the image. And you can easily find out the image location.

  • How to get absolute path of a form within the Forms

    Aslam o Alikum (Hi)
    How to get absolute path of a form within the Forms 6i or 9i
    For example
    i am running a from "abc.fmx" from C:\myfolder directory
    can i get the form path 'C:\myfolder' by calling any any function from "abc.fmb"

    There is no direct call that will always work. What you need to do is call get_application_property(current_form). This may have the full path in it, depending on if that path was defined when the form was launched. If there is no path, then you need to use TOOL_ENV.GETVAR to read the Forms<nn>PATH and the ORACLEPATH, parse those out into individual directories and then check for the FMX in each.
    I already have some code to do all this for you see:

  • I am using the window xp and firefox 6. I see many videos on youtube. How I get that videos from the catch folder and where is it?

    I am using the window xp and firefox 6.
    I watch the youtube videos online.
    How I get that video from the catch folder and where that catch folder are situated in the window xp.

    ''How can I view or retrieve a video from Firefox's cache''
    To actually view/retrieve the file from the cache and its web address you can use
    the "Cache Viewer" extension 32.8KB
    * https://addons.mozilla.org/firefox/addon/cacheviewer/
    * http://dmcritchie.mvps.org/firefox/firefox.htm#cacheviewer
    For you to be able to view the cached file you would have had to have watched the entire file.
    The latest version of the extension is 0.7b available in all versions you would have to override compatibility by any of these methods
    * checking or pick up one of the xpi versions in the reader comments for Firefox 6.0
    * extensions.checkCompatibility.6.0 set to False
    *: http://kb.mozillazine.org/Extensions.checkCompatibility
    * or with an extension "Add-on Compatibility Reporter" (84.0 KB) seems preferred in this group
    *:https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/
    There are also extensions such as Video downloader 132.8 KB
    * Download YouTube Videos + Flash Video Downloader / Download-Helper

  • Is it possible to personalize the size or the Path to your cache, history, temporary files and others?

    Is it possible to personalize the size or the Path to your cache, history, temporary files and others? If it is, how can I do it?
    I explain why. I am willing to create a RamDisk partition where I would place that kind of files with support to a bigger size, that way increasing my speed in Internet, and avoiding permanent writes in the SSD drive.
    I am in i7 920 CPU, with system and programs working in a SSD drive and have 24 GB of RAM memory.

    Hi cor-el
    In my Desktop I have the 9.0.1 version of Firefox.
    I don’t know if it is or not the portable one, but I presume not.
    I couldn’t follow your first link, because page is not found.
    The second link takes me to somewhere where I have already been and that gives no solution to my question.
    I don’t want to disable cache in Firefox. By the contrary, I want it enabled and I’m trying to make it more efficient, making it bigger and placed in a very fast driver (A RamDisk driver, which is a driver made from RAM memory).
    '''''What I want is to configure by myself the place where the cache and other temporary files are placed in my computer, and their size.'''''
    So, I repeat my first question. Is this possible?
    Although I am Portuguese you don´t need to redirect me to Portuguese pages, cause I’m perfectly familiar with English.
