Logging
Xmlsh uses the Log4J subsystem for logging.
Configuration
On startup, xmlsh checks to see if Log4J has previously been initialized, and if so no action is taken.
If the environment variable XLOG4JPATH is set then it is used as the path to a log4j configuration file.
If no XLOG4JPATH is set or if the file cannot be parsed then the following is used to choose a file to log.
- if XLOGFILE is specified then it is used as the log file
- if XMLSH is set then $XMLSH/xmlsh.log is used as the log file
- if the java user.home system property is set then xmlsh.log in that directory is used
- if the java user.dir system property is seth then xmlsh.log in that directory is used
If a file is is found to log then a simple FileAppender is used for logging to that file.
If no file is found then the BasicConfigurator is used (which logs to stderr).
