Please give us some more information.

1. Can you connect successfully to the Oracle database at all with SQL Developer?
2. Is this an existing Oracle database that you connected to successfully in the past, or is this a new Oracle database?
3. Are you sure that using SQL Developer for this migration is the best option?
4. Have you tried setting up a database link from Oracle to the SQL Server database?
5. Where is the SQL Server database?  Is it on the same server as the Oracle database, or on a different server?
