trigger on view

I try to create ea trigger on View
---

CREATE TRIGGER "GECOM"."IN_VW_FATTOMEGA" INSTEAD OF     INSERT
    ON "VW_FATTUREPEROMEGA"
    FOR EACH ROW
---

and when I compile i got alway an ORA-25005 error

CREATE INSTEAD OF impossible on view only read.

BUt is possible this on View or I must create a Materialized View from the Query Tables.
