Logging in a jar

[Gabriel Beres]

Hi!

I using log4j, to log my inner workings of my code.
My problem is, when my codes are in a jar file, log4j can't figure out the exact line number, where an event has happened for example:

java.lang.Exception
at my.package.MyClass.myMethod(Unknown Source)

In eclipse, there are no problem, because the source files are there.
How can i attach sources to a jar file, so log4j could find the exact line?

Thanks

Take a look at the compiler documentation and look for the "-g" options. They add debug information to generated class files.

Thanks Joe!

javac -g works great.
