You need two things to get the source code line numbers:

1) When you compile the code you will be analyzing, you need to use the
-g switch to javac. Otherwise, javac does not insert source line
information into the bytecode, so Soot does not find it there.

2) You need to give the -keep-line-number command-line switch to Soot.
Otherwise, by default, it throws away the source line numbers to save
memory.

Hope that helps.
