In its continued commitment to interoperability, Microsoft provides a Java Database Connectivity (JDBC) driver for use with SQL Server 2005. The SQL Server 2005 JDBC Driver is available to all SQL Server users at no additional charge, and provides access to SQL Server 2000 and SQL Server 2005 from any Java application, application server, or Java-enabled applet. This driver is a Type 4 JDBC driver that provides database connectivity through the standard JDBC application program interfaces (APIs) available in J2EE (Java2 Enterprise Edition).Microsoft SQL Server 2005 JDBC Driver 1.1.1501.101
