Examples of org.apache.derby.jdbc.EmbeddedDriver

org.apache.derby.jdbc.EmbeddedDriver
ew org.apache.derby.jdbc.EmbeddedDriver(); When loaded in this way, the class boots the actual JDBC driver indirectly. The JDBC specification recommends the Class.ForName method without the .newInstance() method call, but adding the newInstance() guarantees that Derby will be booted on any Java Virtual Machine.
Note that you do not need to manually load the driver this way if you are running on Jave SE 6 or later. In that environment, the driver will be automatically loaded for you when your application requests a connection to a Derby database.
Any initial error messages are placed in the PrintStream supplied by the DriverManager. If the PrintStream is null error messages are sent to System.err. Once the Derby engine has set up an error logging facility (by default to derby.log) all subsequent messages are sent to it.
By convention, the class used in the Class.forName() method to boot a JDBC driver implements java.sql.Driver. This class is not the actual JDBC driver that gets registered with the Driver Manager. It proxies requests to the registered Derby JDBC driver. @see java.sql.DriverManager @see java.sql.DriverManager#getLogStream @see java.sql.Driver @see java.sql.SQLException
