经过漫长的6个月的等待，微软官方终于发布了SQL Server JDBC 1.1版本的驱动，不过该版本为CTP(Community Technology Preview) 社区预览版，主要修改了所有已知的bug。
这里引用SQL Server JDBC项目一名开发人员 Angel 的一段说明：

Announcing the June 2006 Community Tech Preview of the JDBC 2005 driver:
http://www.microsoft.com/downloads/details.aspx?familyid=f914793a-6fb…

This preview contains all the changes of CTP 1 including Integrated
Security, it includes rollup fixes for all the QFEs we have shipped to date
and we have addressed most customer issues filed through the product
feedback center.

To round it off we have also added a brand new feature: Client Failover. As
far as I know this is the first JDBC driver to take advantage of Sql Server
2005 Database Mirroring. This feature has been fully documented for this
CTP, we could really use feedback on both the functionality and the docs.

For a complete change list take a look at the release.txt file that ships
with the package, for the first time we are providing comprehensive
information on the work we have done since v1.0, let us know if this is
helpful information.
