      Description



      Name: jn10789 Date: 03/11/99


      The java security mechanisms in 1.2 do not seem to handle
      the following problem directly. Let us assume that I run an
      applet or application that I do not completely trust. I
      am willing to give the software permission to create,
      read, or write specific files or files in specific directories.
      I can use the security mechanisms to do this for specific
      files or directories, using wildcarding, if I know enough in
      advance, but I cannot do this at runtime. An example might
      be a web-page installer that would create a directory tree
      from a zip file, customizing the files in some way, but with
      the target directory known only when the installer runs.

      This could be handled better from the end-user's perspective
      using one or both of two mechanisms.

      One would be to extend
      Swing components to provide dialog boxes to open or write files
      with the file-open operation included in the component. Since
      the component is part of the JDK, it would not be necessary to
      trust whomever provided the applet or application.

      The second would be to provide some sort of security request
      as parameters to an applet, or as part of the manefest file
      in a jar archive. A browser or javarunner would then look
      at this information and grant the appropriate permissions
      (after asking the user) before allowing the applet or
      application to run.

      If provided, this would enable the safe use of applications
      obtained over the net. As it stands now, I cannot run
      an applet that implements a spreadsheet, with the spreadsheet
      data stored on my file system, and where I specifically give
      the applet the file to read or write, without going to
      special efforts to set up the appropriate permissions for
      that applet, including predicting where I will want to place
      the files the applet uses.

      While the security mechanisms in Java 1.2 can allow the above
      to be implemented, the classes that do this need to be
      standardized before users will be comfortable.
