The jboss-log4j.xml is the correct file to modify. There is currently no specific category for jboss.ws in that file, you could add one: <category name="org.jboss.ws"> | <priority value="ERROR"/> | </category> You could also change the FILE and CONSOLE appenders to log only ERROR messages (highly recommended when doing performance testing).
