The second Community Technology Preview (CTP) of Microsoft JDBC Driver 4.0 for SQL Server has just been announced. This CTP includes bug fixes based on your feedback and additional features in “Denali” such as Client side support for SQL Server AlwaysOn Feature for Denali (Support for multi-subnet failover for AlwaysOn and connecting to read-only replicas for AlwaysOn). We have also added full support for Type-4 Kerberos Integrated Security and Support for SQL Azure. Let us know how we’re doing and give us your feedback through the Microsoft SQL Server Data Access Forum, Microsoft Connect, or JDBC team blog. We also actively monitor TheServerSide forums as well.
