log4j

I want to create a custom logger that writes from messages from executors in a specific folder in a cluster node. I have edited my log4j.properties file in SPARK_HOME/conf/ like this: log4j.rootLogger=${root.logger} root.logger=WARN,console log4j.appender.console=org.apache.log4j.ConsoleAppender log4j.appender.console.target=System.err log4j.appender.console.layout=org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n shell.log.level=WARN log4j.logger.org.eclipse.jetty=WARN log4j.logger.org.spark-project.jetty=WARN log4j.logger.org

I have about 8 different webapps written where the only real difference between the log4j property files is the log filename. However if I attempt to move log4j from the webapp WEB-INF/lib directory to the tomcat5 shared/lib directory I run into problems. All the property files basically look the same as the one below, where I just set file.name using System.setProperty("file.name", ) in the code. Not necessary really, but I was toying with

I use SLF4J with log4j in my maven project. Everything is ok when i running the project in tomcat in eclipse, and in maven with tomcat maven plugin. But when i put the war in my tomcat production server, the project don't start, giving me this error. java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND bound slf4j-log4j12.jar on the class path, preempting StackOverflowError. See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details. I already saw many answers in stackoverflow about this error and i already understood i need to exclude the conflict jar.
