Just open the log with a text editor and tell it to find "ERROR" as a case-sensitive whole word. (If your text editor doesn't do that, get a better text editor!) JBoss AS versions 4.x and 5.x used Log4J for logging. Look for the server/xxx/cong/jboss-og4j.xml (or just log4j.xml in earlier versions). To limit server log output to ERROR, add a threshold line to the FILE appender, as shown below (this text is from 5.1.0, other versions migth differ slightly in their contents):    <appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">       <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>       <param name="File" value="${jboss.server.log.dir}/server.log"/>       <param name="Append" value="true"/>       <param name="Threshold" value="ERROR"/>  <!-- add this line -->       . . .    </appender> -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/787692#787692] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
