[webkit-help] websetting error

[EBerry-EdBook]

hi to all

In my applicationc i am using webkitwebview .
I am changing its settings using WebKitWebSettings' 
but when i tried to change it it shows me error


(a.out:5271): GLib-GObject-WARNING **: IA__g_object_set_valist: object
class `WebKitWebSettings' has no property named
`enable-file-access-from-file-uris'

(a.out:5271): GLib-GObject-WARNING **: IA__g_object_set_valist: object
class `WebKitWebSettings' has no property named `enable-java-applet'

(a.out:5271): GLib-GObject-WARNING **: IA__g_object_set_valist: object

(a.out:5271): GLib-GObject-WARNING **: IA__g_object_set_valist: object

(a.out:5271): GLib-GObject-WARNING **: IA__g_object_set_valist: object
class `WebKitWebSettings' has no property named `enable-page-cache'



my code is 

WebKitWebSettings* settings = webkit_web_view_get_settings(webview);
g_object_set (G_OBJECT(settings), "enable-file-access-from-file-uris",
state, NULL);
g_object_set (G_OBJECT(settings), "enable-java-applet", state,
NULL);...................
does any one knows how to change these settings
