Hi....
if (col1,col2,col3) are forming primary key means, then how come you
insert value for any one of primary key columns, if so it would not give error for NOTNULL....

Hamid,
Change your trigger as follows:
Create or replace trigger cre_PK
before insert
declare
loc_seq number;
begin
select seqname.nextval into loc_seq from dual;
insert into tableA(col1) values(loc_seq)
end
/
Hope this helps
