Log 4j configuration for adding file name and line number

Question

I am using Log4j for logging my application activity. In my local environment it was logging like

Fiilename:linenumber: your logging message

then I created archive and deploy in another environment then its logging without file name, can any one clear me which property if logger do this. thanks

Only without filename, but still with line number? Code that is release built don't contain line number information. — Kaj

In log4j.properties file set

log4j.appender.FILE.layout.conversionPattern=%d{yyyy-MM-dd HH\:mm\:ss,SSS} %-5p %l - %m%n

Here %l specifies to generate the location information. According to the spec for PatternLayout : "The location information depends on the JVM implementation but usually consists of the fully qualified name of the calling method followed by the callers source the file name and line number between parentheses."

Look at the documentation for PatternLayout. Note that figuring out file name and file number is slow (I guess it involves getting a stack trace and analyzing it).
