[jboss-jira] [JBoss JIRA] Updated: (JBAS-4432) Log4J does not output JSF 1.2 implementation logging messages

Log4J does not output JSF 1.2 implementation logging messages -------------------------------------------------------------- Key: JBAS-4432 URL: http://jira.jboss.com/jira/browse/JBAS-4432 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: JavaServerFaces Affects Versions: JBossAS-4.2.0.GA Reporter: Anastasios Georgousakis Assigned To: Stan Silvert Fix For: JBossAS-4.2.1.CR1, JBossAS-5.0.0.Beta3 JSF uses java logging to output logging messages. JBoss include org.jboss.web.jsf.integration.config.JBossJSFConfigureListener to set a filter in java logging system in order logging messages to be handled from log4j. The problem is that setting only the filter is not enough because JSF implementation is checking if level is configured before calling a method to out put a message. e.g if (LOGGER.isLoggable(Level.FINE)) { LOGGER.fine("Converting buffered ServletOutputStream bytes" + " to chars using " + encoding); } If you define in jboss-log4j.xml to enable logging for JSF implementation this will not have any effect and JSF messages will not be displayed. A workaround is to change the level of JSF logging if you find that specific levels are enabled in log4j configuration. I changed setLog4J in JBossJSFConfigureListener to set java logging levels for JSF logging categories with the following code. /** * If Log4J is being used, set a filter that converts JSF RI java.util.logger * messages to Log4J messages. */ private void setLog4J() { Filter conversionFilter = new Log4JConversionFilter(logConfigMessages()); setLog4JFilter(Util.FACES_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.APPLICATION_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.CONFIG_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.CONTEXT_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.LIFECYCLE_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.RENDERKIT_LOGGER, conversionFilter); setLog4JFilter(Util.FACES_LOGGER + Util.TAGLIB_LOGGER, conversionFilter); } private void setLog4JFilter(String loggername, Filter conversionFilter) { java.util.logging.Logger jdkLogger = java.util.logging.Logger.getLogger(loggername); jdkLogger.setFilter(conversionFilter); Logger jbossLogger = Logger.getLogger(loggername); if(jbossLogger.isTraceEnabled()) jdkLogger.setLevel(Level.FINEST); else if(jbossLogger.isDebugEnabled()) jdkLogger.setLevel(Level.FINE); else if(jbossLogger.isInfoEnabled()) jdkLogger.setLevel(Level.INFO); }
