Why can I not see my tables?

Hello guys!

I'm trying to create a simple "database" in Oracle 10.

The if I get it right with users and tbale space I will do:

1) Create a database for eg mydatabase.
2) Log in as sys as dba to mydatabase and create a user for eg my user.
3) Log in as my user and create the tables.

I do above (2 and 3) in sql plus
But when I log in as myuser with Toad I can not see my tables in schema browser. (But I can execute selects)

Do see any missake I do?

In 2 I do:
sqlplus -s sys/thepassword@mydatabase sysdba @user.sql
(
CREATE TABLESPACE mytablespace
  LOGGING
  DATAFILE 'C:\mytablespace.DBF'
  SIZE 32M
  AUTOEXTEND ON
  NEXT 32M MAXSIZE 2048M
  EXTENT MANAGEMENT LOCAL;



CREATE USER myuser IDENTIFIED BY thepassword DEFAULT TABLESPACE mytablespace;

GRANT CREATE SESSION TO myuser;
GRANT CREATE SEQUENCE TO myuser;
GRANT CREATE PROCEDURE TO myuser;
GRANT CREATE TABLE TO myuser;
GRANT CREATE VIEW TO myuser;
)

In 3 I do:
sqlplus -s myuser/thepassword@mydatabase as sysdba @init.sql
(
CREATE TABLE Countries
(
    id INT NOT NULL,
    name VARCHAR(255) NOT NULL,
    PRIMARY KEY (id)
) TABLESPACE mytablespace;

DROP SEQUENCE Sequence_Countries_id;
CREATE SEQUENCE Sequence_Countries_id
START WITH 1
INCREMENT BY 1
NOMAXVALUE;
)

Best regards
Fredrik
