log4j relative path to create log file

Here is my log4j.properties file

# Define the root logger with appender file
log = D:/workspaces/Abhishek/Automation/MOPS/logs
log4j.rootLogger = DEBUG, FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FILE.File=${log}/log.out

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%d{ABSOLUTE} %5p  - %m%n

This does job for me only problem is the absolute path i have used. I want to use relative path now.

Below is my folder structure

--src
      --com
      --log4j.properties
--logs
     --log.out file

So my logs folder is outside the src folder where log4j.properties is situated?

How can i define relative path in such case. In case of jsp's we do it like ../webpages/page.jsp. How can it be achieved here ??

On Linux with Tomcat and webapps this works:

log4j.appender.file.File=./logs/your.log

It's in /your/tomcat/webapps/your_app.war/WEB-INF/classes/log4j.properties

And it puts the log file in /your/tomcat/logs/ folder.

P.S. As I found out recently, it's not a good idea to use relative paths in this case. Because you can run the tomcat from different folders, not just tomcat_home/bin/ So, the best answer is by Piaget Hadzizi

I had the same problem and I simply changed the following line

log4j.appender.file.File=logs\\myLogFile.log

And it worked fine relative to the current working directory

you can pass dynamic value like this

{logfileLoc}/logs/file.log.

in your case you want in the project folder itself so can have -D (java argument or equivalent) param like -D logfileLoc =D:/workspaces/Abhishek , and you can access with variable logfileLoc. and consider changing this value for different environments.
