Missing files: com.ms.security.* and netscape.security.*

[Matt Kidd]

I am decompiling and recompiling an application that uses an applet and these to libraries are missing. I realize they are somehow associated to the signing of the applet but I currently do not have copies of them. Anyone know where I can get a copy?

Both are way, WAY, obsolete. Neither Microsoft nor Netscape have a JVM any more, so the only way to sign applets is the official one described in the Sun JVM documentation. Some related info can be found in HowCanAnAppletReadFilesOnTheLocalFileSystem.

I figured as much with my googling today...and with your post I checked the code one more time and this dawned on me:

      try
    {
      if (Class.forName("com.ms.security.PolicyEngine") != null) {
        PolicyEngine.assertPermission(PermissionID.SYSTEM);

        PolicyEngine.assertPermission(PermissionID.FILEIO);
        PolicyEngine.assertPermission(PermissionID.USERFILEIO);
      }

    }
    catch (Throwable localThrowable1)
    {
    }

    try
    {
      if (Class.forName("netscape.security.PrivilegeManager") != null) {
        PrivilegeManager.enablePrivilege("UniversalFileRead");
        PrivilegeManager.enablePrivilege("UniversalFileWrite");
        PrivilegeManager.enablePrivilege("UniversalConnect");
        PrivilegeManager.enablePrivilege("UniversalPropertyRead");
      }

    }
    catch (Throwable localThrowable2)
    {
    }
  

if I'm writing code to replace this applet....why do I need this batch of code which is located in the init method?

I'm so hating hackin this app just get this enhancement installed just to be a stop gap before we upgrade the whole application.



I think I'm just going to forgo trying to find this and just refactor this so the code doesn't run....

Those statements do in a Microsoft/Netscape JVM what in a (these days) standard Sun JVM applet signing does. So if the applet is signed, none of that is necessary.
