Not many people know we have a SQL JDBC driver at all, well now we've got a beta version for SQL Server 2005.  It works for a wide variety of OSs including: HP-UX, IBM AIX, Linux, Solaris, Windows 2000, Windows Server 2003, or Windows XP.  Apparently it goes a lot better than the old (SQL 2000) driver (well we've written this one ourselves), and it will work against SQL 2000 to boot.  You can find it here: http://www.microsoft.com/sql/downloads/2005/jdbc.mspx

The SQL Server 2005 JDBC Driver Beta 1 includes:

• Support for SQL Server 2000 & SQL Server 2005
 
• Support for JDBC 3.0
 
• Improved performance
 
• Improved XA transaction support
 
• BLOB and CLOB support
