The driver included with SQL Server is version 2.2 of DataDirect’s 
JDBC driver.  The current version of Connect for JDBC commercially 
available from DataDirect is 3.3 and offers a Type 4 JDBC driver for 
high-performance database connectivity for all major databases - 
Oracle, DB2, MS SQL Server, Sybase and Informix. Our drivers support 
the latest database features, such as JTA (Java Transaction API) and 
Windows Authentication for SQL Server.  More Information may be found

We do not know of any issues with the SequeLink JDBC driver.
