Are you habit to have some configuration files packaged inside the jar of your application? If so, you can still have a look at those configuration files in the running environment using the unzip Unix utility. $ unzip -p /opt/myapp/lib/my-app.jar log4j.properties log4j.rootLogger=INFO,stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Threshold=INFO log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{dd-MMM hh:mm} [%-5p] %m%n The -p option uncompress and prints [...]

Switzerland is famous to have a low unemployment rate, and Zurich is known to be an international [...]

I feel safe in managing my tasks on computers when I can always undo last operations and restore a working environment. For that reasons tools like cvs, subversion, git, etc. do exist.
