jTDS SQL Server

...
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection connection = DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433/testdb","sa", "");
dba = DBAccess.getDBAccess(connection);
dba.open();
put("dBAccess", dba);
...
Using jTDS 1.2.5 to the SQL Server connection,
"Invalid object name 'sys.database_principals'." I get the error.
What can I be missing.
