Unknown Source

Thread view:

When an exception is thrown during execution, the stack trace is
reporting "Unknown Source" instead of a <source filename:line number>.
I suspect because the source cannot be found from the current working
directory.

How do I tell the JVM where to look so that it can report line numbers
properly?

Thank you.

It does not need access to the source files in order to report the line
number. It just needs to know the line number. The "-g" option to the
"javac" compiler controls whether this information is included in the
class files.
