Not sure about the endless loop, but the first message you see happens because
Log4j default initialization which happens upon JVM startup cannot find a log4j
config file. I suggest you put a log4j config file in (assuming you use Tomcat)
CATALINA_HOME/common/classes to avoid the error message. This would be Tomcat's
logging. Then either use a logger repository selector or put log4j.jar in
WEB-INF/lib of your app. I also suggest that you put a dummy log4j.xml file in
WEB-INF/classes to avoid warnings like the above just before you do your manual
configuration... or just rename your config file "log4j.xml" and let default
initializtion do its work. You aren't doing anything special in your
configuration, so there is no reason to do it manually.
