Tables created using Enterprise Console Manager do not show up in SQLPLUS

Question

I am struggling with Enterprise console manager and command line SQLPLUS.
I have tried scott/tiger , system/manager and the new user that I have created. But I am having the following problems:
1. I cannot connect as NORMAL through Enterprise Console Manager if I use scott/tiger OR new/paswd. Only way I can connect as NORMAL is using system/manager
2. The tables that I create using Enterprise Console Manager (while connected as system/manager in NORMAL mode) do not show up in the command line SQLPLUS. I am check this by running the following command:
SELECT OWNER, OBJECT_NAME FROM ALL_OBJECTS WHERE OBJECT_NAME LIKE '%TEST%';
While running the above command I am conected to SQLPLUS using system/manager WITHOUT SYSDBA
3. Lastly, I have a JAVA class which establishes as connection to the database using system/manager. But I can access only the tables that I create using the Enterprise Console Manager. If I create a table using command line SQLPLUS (while connected as system/manager), I cannot access it through Java program.
I am struggling with this since last morning and now I have run out ways to debug what is happening. Can anybody suggest any ways to tackle this?
Thanks in advance,
Mahesh

Prior to 11g, when you created a table or whatever, you automatically allocated one extent.
This is now no longer true and depends on a parameter I don't remember.
dba_segments is a summary of dba_extents.
Obviously, if there is no extent allocated, the table (view is defined with inner join) will not show up.
You could qualify this is as a bug and submit a SR to Oracle. But then the performance impact may be huge.
