About import modules

Hello. I use PythonInterpreter in Java to run Jython. How i can import
my modules in code? When i trying to run, i have ImportError: No
module named code1, but i does interp.exec(code); code from code1
module before i run code with import:
import sys
from code1 import *

for param in sys.argv:
        print (param)
print('Hello, World type 2')
print(add(1, 2))
