I didn't explain my situation fully.
 
I already knew it's possible to access path-constants declared in root-directory. In my case, there are two different files, nomal Jamfile and *.jam. In each sub directory, there are some *.jam files. I want to use path-constants in those files, I mean *.jam files.
 
Root-dir) Jamroot - declear path-constants : root-dir
Sub-dir) Jamfile - just build it's own project, *.jam - some rules, I want use path-constants here 
 
Thank you for your response though. :)
