e233. Loading a JDBC DriverBefore a connection to a database can be established, the JDBC driver for that database must be loaded. Drivers automatically register themselves with the JDBC system when loaded. There are two ways to load a JDBC driver. The first is to specify the driver or colon-separated list of drivers on the command line:> java -Djdbc.drivers=com.company1.Driver:com.company2.Driver MyAppThe second, and recommended method, is to call Class.forName()
within the code:
try { // Load the JDBC driver String driverName = "org.gjt.mm.mysql.Driver"; Class.forName(driverName); } catch (ClassNotFoundException e) { // Could not find the driver }
