SecurityException when creating a root preference node on Vista

When creating a root preference node (Preferences.systemRoot()) on Vista, I always get a SecurityException. This happens even when running from an administrator account. Has anyone seen this behavior and/or found a workaround?
Basically, I want to store an application preference (a license key) that will hold for any user on the same machine running my Swing app. This rules out calling userNodeForPackage. I've also looked at using systemNodeForPackage, but the javadocs say "This node is not intended for long term use, but for convenience in the early development of programs that do not yet belong to a package, and for "throwaway" programs. Valuable data should not be stored at this node as it is shared by all programs that use it."

Hello, Lars,
My guess is: as it's a 0..N node, when you dinamically add the node, it's not been initialized, as the parent node is empty (no elements). So, when you try to get its reference, it doesn't exist yet. That's why when you set the cardinality of the node to 1..N (or 1..1) it doesn't generate the error, as the WD4A framework initializes the parent node with at least one element, that can have a child node.
What happens if you initialize your node before trying to get a reference to it? For exemple, a bind_table (or bind_element) call before:
o_attr_context_node = o_context_node->get_child_node( name = '_ATTR' ).

  • Sharepoint 2013: Problem / Error when creating Variation Hierarchy for French and German Languages from Variation root EN

    I have a website with English and Arabic Language Packs installed. I have the corresponding Variation heirachies created and the whole site collection is published.
    Recently the client asked for french and german languages to be accomodated as well. So I followed the same approach I did for English and arabic (installed the language packs) for foundation, ran ocnfiguration wizard, installed server language pack &
    ran configuration wizard.
    But after creating the variation label, when i try to create the variation heirarchy, I am getting the following error.
    "Unknown failure when creating a variation of page http://server:port/en/pages/default.aspx in label /fr/Pages/default.aspx.
    The Variations Create Hierarchies job failed with the following error message&  Unknown failure when creating a variation of site
    http://server:port/en in label fr."
    Am not sure what is going wrong. Appreciate a feedback.

    According to your description, my understanding is that the error occurred when you created the Variation Hierarchy for French and German Languages from Variation root EN.
    I recommend to check the Resources folder located at C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15 to see if the file exists in the folder.

  • Dreamweaver 8 is removing forward slash when creating pages

    Dreamweaver 8
    Links set to be relative to Site Root
    If I create a template that has ../index.php as the home link, and also create a few pages from that template, the links on those pages all start with a forward slash:
    However, if I then change the template to have a home link like this:
    and then save, all the links in the already-built pages suddenly lose their site-root forward slash and instead look like this:
    and the home link now looks like this in the created pages:
    ../  (yep, it stays like that)
    I did not change links to be relative to document
    Hmmmmm.....I'm noticing that it's occurring when I edit the template, when you then save the edited template, it updates all the pages made with that template but then all the links are now without the front forward slash, so it looks like this is getting triggered when the template is edited
    It doesn't change how the links are in the template ../whatever, but all the updated links in the built pages now do not have a front forward slash
    And once it changes to the non-forward slash version, it never goes back, it stays as link/
    Does anyone know what might be wrong? I need all the links to stay as /relative-to-site-root/

    It was regarded as a bug in previous versions, and was fixed
    in the 8.0.2
    release. In normal circumstances, ALL links in a template
    file must be
    relative to the template document, not relative to where you
    intend to save
    the child pages. Thus, there would be no way to have a link
    in your
    template document like the first one you show, e.g.,
    <img src="whatever.png"....

  • How to create/reset root password on OSX Yosemite

    I am currently a standard user on a late 2008 Macbook Pro. There are two users on my computer, mine and another admin account. I do not know the password to the admin account. Before I upgraded to OSX Yosemite I had created a root user password in SUM using the command "passwd". After I upgraded (I reset my computer) I was back at square one, me as a standard user and another admin account that I didn't know the password. After I upgraded the “passwd” command didn’t work.
    I tried to obtain the root password using multiple SUM commands like, "rm /var/db/ .AppleSetupDone" which didn't work because it said that it couldn't find the file. Then I tried to use the command, “/System/Library/LaunchDaemons/” and then entering “passwd”. However that didn’t work. (Everything I did was after I mounted the drive.)
    So I was wondering if anyone on the forums knew of a way for a standard user to reset the root password without the knowledge of the admin password.
    Thanks in advance.

    Hey SamuraiPizzzaCat,
    Thanks for the question. After reviewing your post, it sounds like you want to use automatic login. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

    The same field should be in editable mode when we go  and edit an existing  Campaign.
    Method GET_I_LANGU.
    if parent_entity->is_changeable( ) = abap_true.

  • The Jtree is not refreshing with new values when mouse click on the node

    hi ,
    I am creating a tree from a vector .The values in the vector is coming from the JTable data after satisfing the some condition. But the data in the Jtable is changing time to time so the data in the vector is also changing .
    But the problem is that when first I create a tree with that data the tree is created but for the next time I click on the tree node the tree is not changing i.e. it is not created with the new values that is stored in the vector at that time .what to do .Please help
    I am using DefaultMutableTreeNode for creating the tree .In starting I have created one root and the one it's child .Now the next subtree of the root child have to be created by this vector data. this subtree should be updated according to the values in the vecter.
    public void valueChanged(TreeSelectionEvent e) {
    //code here
    //some function that create tree after cheching the some condition here
    subtreecreat() {
    Enumeration en=vector.elements();
    DefaultMutableTreeNode servername = new DefaultMutableTreeNode(en.nextElement());
    Please help it is very urgent
    Thanks in Advance,

    Well, you can either use a custom TreeModel that tracks your Vector, or you can use a DefaultTreeModel and call model.reload(node) to refresh the tree below the specified node.

    Generally when creating a Word file from either a Mac or Win7 pc and opening it on two different machines (either one first) it always prompts that the file is open and will be opened as read only.
    However opening a CSS file does not prompt that it is already open on or from any machine which is causing code edits to be lost.
    What we found from out testing:
    - The file can be saved from one user to the server and WILL NOT PROMPT on other machines until the saving machine has the Dreamweaver program closed completely
    - The file can be closed and  Dreamweaver minimised to the launch bar but it still will not register on other machines that it has been changed.
    - Also, until the  Dreamweaver program is closed on the machines, it will continue to open it's saved version of the file. 
    Example Scenario:
    - User 1 opens test.css (which is 2000 lines) and adds some code to the end of the file to bring it up to 2500 lines
    - Meanwhile User 2 opens test.css as well (opens as 2000 lines as User 1’s edits have not yet been saved) and adds in code to bring it to 2300 lines
    - User 1 saves his file and closes it - but  Dreamweaver is still open.
    - User 2 also saves his file and leaves  Dreamweaver  open.
    - The server will report the size and last edit of the file the same as User 2 as he was the last person to save it (and if you open from the Win7 Machine it will show as User 2’s 2300 line version)
    - If User 1 then open's the file again (from either the 'recent' in Dreamweaver OR clicking on the file directly in Finder...which version opens.... The version that User 1 saved! Not the true version on the server, but the version that User 1 edited and saved with 2500 lines in it.
    - Same for User 2, he will open 'his' version with 2300 lines in.
    Other information:
    - Files are opened directly from the server
    - Sometimes the users will save incrementally and re-open
    - Most of the time users will save incrementally and keep the files open
    - The users will never not save incrementally and just save when closing the file once finished
    - The users are usually working on the files all day
    - It is always the bottom lines of code that are lost. It could be a case of the two versions being mixed up and cutting off the newly added lines based on the line count (possibly).
    It is as if Dreamweaver is holding a cache of the version locally and then only properly looking back to the server when it has been completely closed. It is very difficult to see how the server is causing such an impact on these files, there are very few logs which are giving any indication to the root cause of the problems.
    Anyone know if this is a known issue?
    Is there a way that there can be a featured implemented on the server that doesn't allow another user to open a file if it is already open on another machine?

    Your server file handling has nothing, and really nothing to do with Adobe software. If files don't get locked for (over-)writing and/or lose connection to the program opening them, then your server is misconfigured. It's as plain and simple and that. Anything from "known file types"/ file associations not being set correctly, MIME types being botched, crooked user privileges and file permissions, missing Mac server extensions, delayed file writing on the server, generic network timeout issues and what have you. Either way, you have written a longwinded post with no real value since you haven't bothered to provide any proper technical info, most notably about the alleged server. Either way, the only way you can "fix" it is by straightening out your server and network configuration, not some magic switch in Adobe's software.

  • When create heirarchy, can not find the entry which is in master data

    Hi, SDNs
        When create a heirarchy for a char , click this char button to add a fields to a node, i can't search the value which is actually in the master data.
       Thansk for your time

    If you go to create hierararchy or change mode of hierarchy
    3 types of nodes you can create
    1)Text node
    2)Charecteristic node
    3)Infoobject values node
    text node - is simple any text node you can create
    infoobject values node - if the master data is loaded you can create it
    if master data is loaded make sure its activated and no master data is under "M" version.
    charecteristic node - only if particular infoobject node is included in the tab "external chars in hierarchies" in RSD1 of that particular infoobject
    Hope it Helps

  • How to change the default save encoding of the dvm files when create dvm???

    When I creating a DVM(domain-value mapping) in Chinese on the ESB control and confirm it, then restarted the SOA service, the DVM that I created in Chinese disappeared from ESB control. All the maps(both English and Chinese ) are in DVM Repository.
    After I updated the encoding from ‘UTF-8’ to ‘GB2312’ in the three files below, and restarted the SOA service, the DVM in Chinese appeared on ESB control.
    But when I adding the second row in Chinese and save it, then restart the SOA service, the DVM in Chinese disappeared from ESB Control once again. Because the encoding in the three files below is updated from ‘GB2312’ to ‘UTF-8’ .
    How to change the default save encoding of the dvm files when create dvm in ESB control ???

    I have the same problem.  When I updated to Mavericks now the bookmarks bar font is huge.  I liked it the way it was before.  I liked the smaller font.  Also wish I could change the color of the sidebar and font/folders too.
    I tried to see in preferences if there was anyway to change it, but I don't see anything there.
