Creates an Identity object from the specified identityName parameter.

Parameters:
identityName a String that represents the identity to be built.
Returns:
the constructed Identity instance, or null if the Identity object cannot be built.
   private Identity getIdentityFromString(String identityName)
   {
      try

      catch (Exception e)
      {
         .debug("Exception caught while constructing Identity object"e);
         return null;
      }
   }

   

Creates a CompositeACLPermission from the specified permissionString parameter.

Parameters:
permissionString a String containing the permissions assigned to the identity, separated by a comma (e.g. CREATE,READ,UPDATE).
Returns:
the constructed CompositeACLPermission object.
   private CompositeACLPermission getPermissionsFromString(String permissionString)
   {
      List<BasicACLPermissionpermissions = new ArrayList<BasicACLPermission>();
      if (permissionString != null)
