Java applet can't access non-public file on same webserver -


I am creating a Java applet for a customer, and I have a problem where I need to read / write For a file on your web server, but that file, in any case, can not be publicly accessible

The Java applet and the file are both on the same server, and I am in the same folder File and .jar file, but if I have them different Trying to access the file in the same folder and 

  test = WorkbookFactory.create (new file ("test.xlsx"))   < P> I have tried writing a full path to the file, and anything seems to work.  
 The error I am getting is:  
 by  Reason: java.security.AccessControlException: access What is the best way to read / write files on a single server What will be seen in public?   
 
 
 If you think Java applets work, there is a basic misconception. They do not run on the server, they run on the client in a web browser. If the client's web browser does not have access to the file, then the applet can not be used.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
