log4j

Background: As usual we have various life cycles like dev. stage, lt, prod all these are picked at deploy time from environment variable ${lifecycle}. So JNDI setting we stores in ${lifecycle}.properties as variable datasource.jndi.name=jdbc/xxx. As other beans are also using this properties file, it is verified that such variable is loaded & file is in classpath, but somehow I am not able to consume this variable in log4j2.xml in below JDBC Appender. <JDBC name="DBAppender" tableName="V1_QUERY_LOG" bufferSize="4" ignoreExceptions="false"> <DataSource jndiName="${sys:datasource.jndi.name}" />

i'm stuck trying to turn off the annoying DEBUG logging of quartz. i'm using log4j as logging framework and i've already tried to add this line to the lg4j proprieties file "log4j.logger.org.quartz=ERROR" i'm still getting tons of these debugging logging messages 13:35:44.680 [MyScheduler_QuartzSchedulerThread] DEBUG o.quartz.core.QuartzSchedulerThread - batch acquisition of 0 triggers how can i turn this function off ? EDIT. i've moved my configuration to xml file...but still getting the same annoying problem <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j

I am using log4j for logging. I have a scenario where I have to use seperate logging for different severity. For example, for package foo I have to print messages with severity ERROR in the console whereas I have to print messages with severity WARN in log file. How can I configure my log4j.xml for the same. You may use LevelMatchFilter for your task. Also you should not forget to use another filter - DenyAllFilter - as the last filter in the chain of filters. Your log4j.xml will look like this: <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name=

Working on Spring MVC and not having Spring logs has made it hard to debug. I have read few other articles on this problem and none seem to help me. log4j.properties is in src folder. slf4j-api-1.5.11 , slf4j-log4j12-1.5.11 , slf4j-simple-1.5.11 , commons-logging-1.1.jar and log4j-1.2.16.jar jars are in the classpath. Log4j content is: log4j.rootLogger=INFO, console # Console appender log4j.appender.console=org.apache.log4j.ConsoleAppender log4j.appender.console.layout=org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern=%d [%-15.15t] %-5p %-30.30c{1} - %m%n log4j
