Since you mentioned log4j.xml, I am going ot assume that you are using a really old version of JBoss AS, such as 4.0.x or 3.2.x. In the 4.0.5 log4j.xml file there is a commented-out category that shows how to set trace level logging: <category name="jbossws.SOAPMessage"> | <priority value="TRACE" class="org.jboss.logging.XLevel"/> | </category> | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4227262#...
