Sorry about that, I hit send before I was done.. // Set up the MDC info so we can pull the variables out in the layouts private void mapToMDC(Map map) { // MDC.getContext().putAll(map); Iterator itr = map.entrySet().iterator(); while (itr.hasNext()) { Map.Entry entry = (Map.Entry)itr.next(); MDC.put(entry.getKey().toString(), entry.getValue().toString()); } } ok, now...those are the helper functions.. // Code to log in the main server // All requests go through this method public void processLogRequest(Map evt) { String mesg = (String)evt.get("message"); if (mesg.startsWith("ROLEVENT)) { Map m = new HashMap(); try { StringUtils.createNVList(mesg.substring("ROLEVENT".length()), ";", m); } catch (Exception ex) { ex.printStackTrace(); } // Set the MDC data mapToMDC(m); } // Create the category to log to Category c = Category.getInstance(((String)evt.get("category_name"))); // Create the logging event from the fields in the Map (evt) LoggingEvent e = new LoggingEvent((String)evt.get("fqn"), c, Priority.toPriority((String)evt.get("priority")), mesg, null); c.callAppenders(e); } In my XML mapping for the category i have: <!-- Appender to the CONSOLE --> <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p %c [%t] %X{user_id} %X{trans_id} - %m%n"/> </layout> </appender> // Process the category <category name="tim.mulle.test" > <appender-ref ref="CONSOLE" /> <priority value="debug" /> </category> I know the category I am receiving all the data becuase I can print it out, it just isn't showing up on the console or in the files, etc. Thanks, Tim ____________________________________________________ Timothy G.

I'm trying to use it in the console appender and nothing is printing out. I have a central logger, which when it receives logging request will try to build the MDC data so I can use the %X{var} patterns. Code: // After receiving the log request Map m = new HashMap(); try { StringUtils.createNVList(mesg.substring("ROLEVENT".length()), ";", m); // System.out.println("Map: " + m); // System.out.println("user_id: " + m.get("user_id")); } catch (Exception ex) { ex.printStackTrace(); } // Set the MDC data mapToMDC(m); private void mapToMDC(Map m) { } ____________________________________________________ Timothy G.
