Help Importing objects from 1 user to another user and problem with trigger

Question

Hello community, i am having a little difficulty with the exporting objects from one user to another specifically the exporting of the trigger.
Here is the situation, because of SOX purpose whenever a update is sent to the client the dba have to execute the script as himself (priviliged user) and is not allowed to log into the schema to make changes. Therefore we perpend the object definitions with &user_schema.. and they define user_schema in sqlplus and execute the update script.
Here is a small example which requires two users (user1 and user2) with the following grants (connect, create table, create trigger, create view, create sequence). Please forgive the naming of the objects, just trying to be as simple as possible.
I start out by logging in as system user via sqlplus and execute the following.
------------------Begin sqlplus----------------------
define user_schema=user1;
create table &user_schema..abc01 (
  col1 number,
  col2 varchar2(20),
  col3 number,
  constraint pk_abc01_col1 primary key (col1)
create table &user_schema..xyz01 (
  col1 number,
  col2 varchar2(20),
  col3 number,
  constraint pk_xyz01_col1 primary key (col1)
create or replace view &user_schema..view1 as
select x.col1, x.col2, x.col3, a.col1 as acol1, a.col2 as acol2, a.col3 as acol3
from xyz01 x
inner join abc01 a on a.col1 = x.col1;
create sequence &user_schema..seq_xyz01 start with 1 increment by 1;
create or replace trigger &user_schema..trig01
before insert on &user_schema..xyz01 for each row
begin
  if (nvl(:new.col1, -1) = -1) then
    select seq_xyz01.nextval into :new.col1 from dual;
  end if;
end;
/--------------------End sqlplus----------------------
I would then proceed to export using the exp utility via the command line
exp system/systempassword file=user1.dmp owner=user1
Then import user1 objects into user2
imp system/systempassword file=user1.dmp fromuser=user1 touser=user2
Now the problem:
When i take a look at the sql for user2 trigger (trig01) i see the following (viewed via sqldeveloper)
create or replace TRIGGER "USER2".trig01
before insert on user1.xyz01 for each row
begin
  if (nvl(:new.col1, -1) = -1) then
    select seq_xyz01.nextval into :new.col1 from dual;
  end if;
end;its referring to user1.xyz01 table, however i want it to point to is user2.xyz01 table. Can someone please help me out or offer another solution to go about this because i need the ability to import the objects into a different user without the import failing and having to recompile the object.
I've also tried executing this while connected as system user via sqlplus:
define user_schema=user1
create or replace trigger &user_schema..trig01
before insert on xyz01 for each row
begin
  if (nvl(:new.col1, -1) = -1) then
    select seq_xyz01.nextval into :new.col1 from dual;
  end if;
end;
/but that fails stating that table or view does not exist, please help
however that fails because i

Answer 1

When performing an update in their system, the same script will be run with different values, thats not the problem.
The client currently have just that one schema in their environment, however they want to have another instance of the application set up in their environment (same database) and have that go off on its own track separate from the original application.
Now when we do an exp of the schema and the imp it into another user it get imported, however its incorrect. As stated before the trigger will be acting on the table in the original schema when it should be acting on the table in the newly imported schema.
I suppose there is no other way around this when a trigger is created the way in which i outlined above. I guess after the data gets imported into a different user the trigger would have to be recompiled to point to the correct table.
If you have an alternate solution to go about this i am open to suggestions. However like i mentioned in the original post because of SOX purpose the dba is not allowed to log in and execute update scripts as the schema user. The scripts should only be executed as that privileged user (dba).
Also if i hard code the user when the trigger is created
create or replace trigger user1.trig01
before insert on user1.xyz01 for each row
begin
if (nvl(:new.col1, -1) = -1) then
select seq_xyz01.nextval into :new.col1 from dual;
end if;
end;
/it still doesn't get imported the way that i want it to be imported in user2
create or replace TRIGGER "USER2".trig01
before insert on user1.xyz01 for each row
begin
  if (nvl(:new.col1, -1) = -1) then
    select seq_xyz01.nextval into :new.col1 from dual;
  end if;
end;now when i do an insert to test
insert into user1.xyz01 (col2, col3) values ('abc', 123); -- Works fine, no problems here
insert into user2.xyz01 (col2, col3) values ('abc', 123);Results in an error ORA-01400: cannot insert NULL into ("USER2".XYZ01"."COL1") because the trigger doesn't exist on user2.xyz01 table.
Just try and create the schema like how i outlined above in your environment to see what i'm talking about. It seems that the only way to get the trigger to be imported the way i want it to is to actually log in as that user and create the trigger.
sqlplus user1/user1
{code}
create or replace trigger trig01
before insert on xyz01 for each row
begin
if (nvl(:new.col1, -1) = -1) then
select seq_xyz01.nextval into :new.col1 from dual;
end if;
end;
{code}
