Data Source Authentication Failed on JBoss Startup

Hi, I'm trying to install on windows 8.1/mysql/JBOSS
but I have the follow error on JBOSS console

JBAS014777: Services which failed to start: service jboss.web.deployment.
default-host./suite

13:01:08,830 ERROR [stderr] (Appian Engine Timer (personalization triggering)) l
og4j:WARN No appenders could be found for logger (com.appiancorp.kougar.driver.i
pc.AppianEngineTimer).
13:01:08,831 ERROR [stderr] (Appian Engine Timer (personalization triggering)) l
og4j:WARN Please initialize the log4j system properly.

What is wrong?
Thanks
Bernardo Giannuzzi
