I have an applet in which am using Java 2D API functions and have granted the file read permission by making a .cab file. Now to execute this applet under IE4.0 I converted it's HTML file using HTMLConverter that Sun provides. Now I tried to execute it under IE4.0, 2D API functions work properly but it is refusing to grant the file read permission. Please help

Have you signed the Cab-Arc with the Signcode-Tool?

example for signing new CAB-Archive

signcode -j javasign.dll  -jp ..\JavaPerm.ini -spc ..\Development.spc -v ..\Development.pvk  UserLogin.cab

Get your Applet the Permisions?

try {
  if (Class.forName("com.ms.security.PolicyEngine") != null) {  
      PolicyEngine.assertPermission(PermissionID.FILEIO);
      PolicyEngine.assertPermission(PermissionID.NETIO);  
      PolicyEngine.assertPermission(PermissionID.PROPERTY);
  }
} catch (Throwable cnfe) {
 .....
}

Dear Blob Thanks for your suggestion but the fraction of code you that you have given here that is there already in my program still it doesn,t asks for the permissions.
Second Thing I came to know that it dosen't takes the cab file at all B'cause I deleted all the class files in the directory where I have kept the .cab file but it show's an error "Class not found" Please try some other stuff.

Wait a moment,
you use the Java Plugin from Sun with the IE?
Are you sure, that the Plugin uses the same Permision-Concepts with the MS-VM? try Sun's Permision and signing Model...
