Reverse engineering: Not listing tables: Oracle 11gR2

Connection to existing oracle 11gR2 is successfull. It is not showing tables.
But I can view the tables using oracle sql developer and query them too.
But it is a read-only access.

I want to reverse-engineer using the wizard. After saving connection, there is an empty list of tables.

Please advise. I am connecting to db over VPN connection.

Hi Prashanth.

Did you select other User in combobox "User / Schema" than your default user?
