> I am writing a JDBC driver. The JDBC Spec has a a method [DataSource.setLogWriter(PrintStream)|https://docs.oracle.com/javase/8/docs/api/javax/sql/CommonDataSource.html#setLogWriter-java.io.PrintWriter-] API drivers should implement.
> Users can drop our driver into any tool that talks JDBC or write their own apps. In am concerned about the 'drop the driver anywhere' scenario, like in an Eclipse based tool; that may or may not use Eclipse DTP. Or anything else.
> The [setLogWriter()|https://docs.oracle.com/javase/8/docs/api/javax/sql/CommonDataSource.html#setLogWriter-java.io.PrintWriter-] API can be called at any time, after Log4j has initialized itself for example.
> I do all my driver logging through Log4j. If a tool calls [setLogWriter()|https://docs.oracle.com/javase/8/docs/api/javax/sql/CommonDataSource.html#setLogWriter-java.io.PrintWriter-], I'd like the given PrintStream to become an Appender such that Log4j output appears there.
> The only way I see to do that is through pseudo-code like "getLoggerContext().getConfiguration().addAppender(PrintStreamAppender.createPrintStreamAppender(aPrintStream))"
> I think that would need to be followed by a full reconfigure.
> Can we use our new builder API to add to the current config and reconfigure?
