Quick Logging on Log4j

Ok occasionally I need to log from a class that I wouldn’t normally log from so wouldnt have configuration setup. An example being a test class

In the class below you simply add the config into a static method –

[sourcecode lang=”java”] public class MyTest {

Logger rootLogger = Logger.getRootLogger();
rootLogger.addAppender(new ConsoleAppender(new PatternLayout("%-6r [%p] %c – %m%n")));

private static final Logger LOGGER = Logger.getLogger(MyTest.class);

public void MyMethod() {
LOGGER.debug("in MyMethod");


Its a hack – but its useful in a hurry
