It sounds like FAQ 6.2:

   http://www.jython.org/cgi-bin/faqw.py?req=show&file=faq06.002.htp

The standard python modules must still be loaded from the filesystem
using the directories in sys.path.

For debugging, try to adding these statements before importing "random":

   import sys
   print sys.path
