Correct. I wrote a JDBC driver that uses Log4j 2 but this is useful for any
JDBC Driver where you want that driver to log to Log4j instead of a
PrintWriter; which is what JDBC forces you to use.
>From the Javdoc for org.apache.logging.log4j.io.LoggerPrintWriter:
PrintWriter pw =
IoBuilder.forLogger().setLevel(Level.DEBUG).buildPrintWriter();
DriverManager.setLogWriter(pw);
DataSource ds = ...
ds.setLogWriter(pw);
