I am having a seperate jar file which do some stuffs. Which is actually deployed in tomcat. Inside that jar I have a java file with main method. Say the class name is StartPoint. I am calling that main method from a shell script by "java StartPoint checkStatus". The main method validates the checkStatus param and do the job accordingly. All java files inside the jar uses log4j and uses log.info/log.debug for logging. These logs are working fine if tomcat is up. Due to some requirement I triggered the main method from a shell script and now I am unable to get those log information. Please help how can I get the logs added using logger.info/debug?

So I believe you just need to make sure that log4j.properties/log4j.xml
is on the classpath when you call the StartPoint main method directly.

I have WEB-INF/lib/log4j-1.2.8.jar in my classpath is this enough? – keyanwb Aug 08 '13 at 11:19

no just jar is not enough, basically log4j reads configuration such as where to put logs(console,file etc), file rolling, logs date format etc from log4j.properties/log4j.xml. You need to make sure that this config file is present in your classpath. – Juned Ahsan Aug 08 '13 at 17:53

Try passing additional parameter with log4j config file path:
-Dlog4j.configuration={path to file}

Hi this should be fine if I am acessing my application using tomcat. What I am using is a stand alone java program which is inside my project's jar. I am calling that particular file alone from shell script. – keyanwb Aug 08 '13 at 11:31

So how are you invoking this app form shell script? Something like this: java -jar
.jar? – kaos Aug 08 '13 at 11:46 -
export CLASSPATH=...all my jars including project.jar-Dlog4j.configuration={path to file} java -cp ${CLASSPATH} com.pack.StartPoint checkStatus – keyanwb Aug 08 '13 at 11:57

You have environment property in CLASSPATH: '-Dlog4j.configuration={path to file}'. I think it shuld be like this java -Dlog4j.configuration={path to file} -cp ${CLASSPATH} com.pack.StartPoint checkStatus – kaos Aug 08 '13 at 12:23
