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).
