We group all the variables physically in the top of our properties file for
visibility.
We then often reuse the variables to build more complex strings.
Should have pointed that out. Sorry.
### top of file
FVIS_layout_pattern_sock=%d{yyyyMMdd HH:mm:ss.SSS} %-5p : %m %n
FVIS_layout_pattern=%d{yyyyMMdd HH:mm:ss.SSS} %-5p : %m <%l> %n
###
### system properties are used to set variables

FVIS.LOGFILE=${fvis.logstem}.log
FVIS.XMLFILE=${fvis.logstem}.xml
FVIS.ERRFILE=${fvis.logstem}.err
..
..
..
log4j.appender.PgmLog.File=${FVIS.LOGFILE}
..
..
..
log4j.appender.PgmXml.File=${FVIS.XMLFILE}
..
..
..
log4j.appender.ErrLog.File=${FVIS.ERRFILE}
is really the same as
log4j.appender.PgmLog.File=${fvis.logstem}.log

log4j.appender.PgmXml.File=${fvis.logstem}.xml

log4j.appender.ErrLog.File=${fvis.logstem}.err

variable in log4j.properties

Please respond to
"Log4J Users

Actually just
System.setProperty("fvis.logging.logfile",mylog);
and in your config file
log4j.appender.PgmLog.File=${fvis.logging.logfile}
should be enough. No need to go through another variable.
