Is there really nobody with an answer for this issue?

I have the following:
- a methodName M
- a Path to a java-file J
I want to find the line number in J where M is defined. Can someone tell
me how to do that?

use the JavaCore APIs, something like this:

ICompilationUnit unit = JavaCore.create(path);
then get the types from it with getAllTypes(), and iterate over the methods
of those types (getMethods()) until you find the one you want and ask for
its source range with getSourceRange(). This gives the start and length of
the
source for the method. I recall there is a way to find the line number given
a source
range, but I can't find it right now. Hope this gets you started.

Yep, indeed, now I got the offset of that method in that file.

So the only missing link is on how to get a line number for a offset and a
file. Somebody knows?

Cheers,

Peter

If you have a org.eclipse.jdt.core.dom.CompilationUnit in hand, then
you simply need to use the lineNumber(int) method using the start
position of your source range.
Does it work for you?
