copy system file without shell cp command

Question

I need to read a 3rd party db file, so far i copyed the file to the sd card using shell su cp to copy the file to the sd card and read it from there using SQLiteDatabase

but on android 4.1.2 I get a message saying the cp command is missing, /system/bin dont have the file.

how can i read the 3rd patry application db?

I dont want to use busy box, it will drive many users away
