How to avoid the message "Unknown source"?

[Richard]

Before I used the option -classic with java but it is not supported anymore.

I would like to know the line where is the problem in my program.

Thanks in advance for your answer.

Use -Djava.compiler=NONE
This will disable the JIT, which is the evildoer that discards
file/linenumber information.

Hello Thomas,

Nothing is changed with the option -Djava.compiler=NONE. My version of
Java : 1.5.0

Perhaps your classes do not contain file/line information. If I
remember correctly, javac does emit this information by default, but
the Ant javac task does not. If you're using Ant, try invoking javac
using code like this:

<javac srcdir="src"
destdir="classes"
debug="on"
debuglevel="source,lines"/>

If you're using the javac tool, make sure you do not have -g:none on
the command line. If no -g option is present, javac will generate file
and line number information.
Hope this helps,
