stack trace: why doens't it show the line number ?

[Walter Stucki]

Hi

Case a) JVM shows in the stack trace the line number if I'm running my
java application with class-files (e.g. ConsoleInput.java:182):

Case b) The JVM doesn't show the line number information if I'm
running the same application as a jar-file (It shows unknown source)

My questions:
- Is the reason for this behavior (doesn't show line number) because
the application is running as a jar?
- Is there a workaround to show the line number in the stack trace if
Im working with a jar?



--------------------------Case a)--------------------------------

You need to compile your sources with the -g flag, in order to ge line numbers
in the class file
