MS SQL custom driver for VA supports the driver posted on sourceforge. This driver is no longer updated or developed and has been that way for several years. Please use the Microsoft JDBC driver. There have been problems with the datadirect driver and the turnaround time from IBM is much longer then the vendor providing and testing their driver. This allows the customer the option to select the vendor's driver directly and keeps the customer from having to choose a driver that is deprecated vs IBM's which can cause connectivity problems.
According to Microsoft, "In our continued commitment to interoperability, Microsoft provides a Java Database Connectivity (JDBC) driver for use with SQL Server, and Azure SQL Database. The driver is available at no additional charge and provides Java database connectivity 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)."
