So, on the client side, I not need add log4j.xml and I can edit file log4j.xml inside conf/log4j.xml ? <appender name="MY_SOCKET" class="org.apache.log4j.net.SocketAppender"> | <!--<param name="Port" value="18770"/>.--> | <param name="Port" value="15000"/> | <param name="RemoteHost" value="mymachine"/> | <param name="ReconnectionDelay" value="30000"/> | <param name="Threshold" value="INFO"/> | </appender> But when I restart JBoss server, I received some errors: anonymous wrote : log4j:ERROR Could not connect to remote log4j server at [pc6.duongtadi.com]. We | will try again later. | java.net.ConnectException: Connection refused: connect Please guid to me. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083334#...
