Log4J Configuration

If you didn't use log4j before, you may want to get started by saving the following to /WEB-INF/classes/log4j.properties:

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %-18c{1} - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=warn, stdout
log4j.logger.de.odysseus.calyxo=info
