The problem of connect and resource role

Question

Hi,
As we know, that while crating a new user, we can assign connect and resource so that the user can access the system tablespace.
The problem that i got is instead of assigning the connect and resource role, i have assigned each and every privilege individually from this role. But, surprisingly, my user has not got the privilege o accessing the system tablespace.
I was working in oracle 9i database. Can anyone help me in this regard and tell me what is the reason behind this?
Thanks in advance.

what huntrex said is quite valid i would like to add some more..
SQL> create user myuser identified  by myuser
  2  /
User created.
SQL> select grantee,privilege
  2    from dba_sys_privs
  3   where grantee='MYUSER'
  4  /
no rows selected
SQL> grant resource to myuser
  2  /
Grant succeeded.
SQL> select grantee,privilege
  2    from dba_sys_privs
  3   where grantee='MYUSER'
  4  /
GRANTEE                        PRIVILEGE
MYUSER                         UNLIMITED TABLESPACEWhen you create a new user, the user is not able to save data until given a tablespace quota.As well when you create user and dont define its default tablespace then it is assigned tablespace what you defined at the time of database creation.If you dont define the tablespace at the time of creating database then it goes to system tablespace.
When you grant resource role then user get unlimited tablespace over specified tablespace while creating users or
default when not mentioning tablespace.
conn myuser/muyuser
SQL> select * from session_privs;
PRIVILEGE
CREATE SESSION
ALTER SESSION[b]
UNLIMITED TABLESPACE
CREATE TABLE
CREATE CLUSTER
CREATE SYNONYM
CREATE VIEW
CREATE SEQUENCE
CREATE DATABASE LINK
CREATE PROCEDURE
CREATE TRIGGER
CREATE TYPE
CREATE OPERATOR
CREATE INDEXTYPEAs you created the user and i assume you didnt specify the default tablespace ,this user goes for system tablespace
but you didnt assign resource role then you will have to have assign quota for that user to create any object within
this created user.
