Not able to retrieve record format for table

Hi
I am using jtopen 4.6 and having problem trying to
retrieve record format for a Physical file when i do
String path = "/QSYS.LIB/%LIBL%.LIB/CF6001.FILE";

but if i hard code the library name it works 

String path = "/QSYS.LIB/MAPS6300BV.LIB/CF6001.FILE";

I have already tested that there is correct library
list on AS400 job.

here is the code snippets

http://code.midrange.com/index.php?id=491c153e61

I get following exception
com.ibm.as400.access.AS400Exception: CPF3012 File
CF6001 in library *LIBL not found.
