JSF RI wrapped commons-logging disables Hibernate commons-logging ----------------------------------------------------------------- Key: JBSEAM-1721 URL: http://jira.jboss.com/jira/browse/JBSEAM-1721 Project: JBoss Seam Issue Type: Bug Components: JSF Reporter: Christian Bauer Hibernate uses this to log stuff: import org.apache.commons.logging.LogFactory; private static final org.apache.commons.logging.Log commonsLog = LogFactory.getLog(...); The JSF RI has a wrapped commons-logging: import com.sun.org.apache.commons.logging.LogFactory; private static final com.sun.org.apache.commons.logging.Log commonsLog = LogFactory.getLog(...); If both are on the classpath (in my case, a SeamTest unit - problem does not appear with regular WAR/EAR deployment on AS), Hibernate doesn't log anything anymore to log4j. In other words, try to get Hibernate log output in a Seam test - no go. Same if you try to use commons-logging directly in your application/unit test: it doesn't work with the normal commons-logging LogFactory, but it works if you take the com.sun wrapped LogFactory. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
