This is the 1-line contents of my log4j.properties: log4j.logger.de.hska=TRACE The contents of a session bean is: @Stateless | @Local(KundenverwaltungDao.class) | final public class KundenverwaltungDaoBean implements KundenverwaltungDao { | public static final Log LOG = LogFactory.getLog(KundenverwaltungDaoBean.class); | ... | if (LOG.isDebugEnabled()) { | for (Kunde k: kunden) { | LOG.debug(k); | } | } | Now, I get the expected log records. However, changing "isDebugEnabled" to "isTraceEnabled" and "debug()" to "trace()" then nothing is logged. Using "-Dlog4j.debug" for log4j's internal log doesn't show anything regarding my log4j.properties (which is part of an EAR's SAR archive). Could it be that JBoss is internally setting the DEBUG level for everything and that's the reason for logging the stuff above with DEBUG level?
