Yes, os requires the javaos module, and you get the ImportError when that
module cannot be Located. Fix= make sure module is found.
Check your python.home/sys.path vars.  Use PythonInterpreter.initialize
before instantiating the interpreter to set properties like python.home so
modules can be found.  The org.python.util.PyServlet code is the best
example of setting properties and the initialize method.
