Data communication between Aplet and Application

[samadmaemo]

Hi,
I want to send data from maemo application to applet using the following code
osso_context_t* osso_context;
osso_context = osso_initialize("com.nokia.feelclose", "0.1", FALSE, NULL);
osso_rpc_async_run_with_defaults(osso_context, "feelclose", "top_application", NULL, (void*)DBUS_TYPE_STRING, NULL, DBUS_TYPE_INVALID);

what should i change for passing messege applet to application and vice versa. Any expert there who can help me.
