I often have problems installing the third-party JDBC drivers using check for updates. The downloaded files are zero length.
To install manually...
Download jtds 1.2. Later versions are unsupported.
Place the jar file somewhere.
In sqldeveloper, go to Tools | Preferences | Database | Third Party JDBC Drivers
Click on Add Entry...
Navigate to where you placed the jar file and select it. Click on OK and close the preferences dialog.
The New connection dialog should now include tabs for SQL Server and Sybase.
