I have put log4j to my buildpath, but I get the following message when I run my application:
log4j:WARN No appenders could be found for logger (dao.hsqlmanager). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
What do these warnings mean? Whats the appender here?
