Note: Download Microsoft SQL Server JDBC Driver 2.0 Community Technology Preview by Microsoft
In its continued commitment to interoperability, Microsoft has released a new Java Database Connectivity (JDBC) driver. The SQL Server JDBC Driver 2.0 download is available to all SQL Server users at no additional charge, and provides access to SQL Server 2000, SQL Server 2005, and SQL Server 2008 from any Java application, application server, or Java-enabled applet. This is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs) available in Java Platform, Enterprise Edition 5.
This Community Technology Preview (CTP) release of the JDBC Driver is JDBC 4.0 compliant and runs on the Java Development Kit (JDK) version 5.0 or later. It has been tested against all major application servers including BEA WebLogic, IBM WebSphere, and JBoss.
