java - Why does Jython not find this module? -

how run python script java?

i running python script using jython , got error:

exception in thread "main" traceback (innermost last): file "c:\facebook\loginpython\facebook.py", line 5, in ? importerror: no module named cookielib

why doesn't work?

a little bit more using jython - had share of problems well. note may not best way it, works fine me.

i assume want call function foo in module bar java code takes string argument , returns string:

    pythoninterpreter interpreter = new pythoninterpreter();     // append directory containing module python search path , import     interpreter.exec("import sys\n" + "sys.path.append(pathtomodule)\n" +      "from bar import foo");     pyobject meth = interpreter.get("foo");     pyobject result = meth.__call__(new pystring("test!"));     string real_result = (string) result.__tojava__(string.class); 

the sys.path.append() part necessary if module isn't part of python search path default, may problem if import or module not find errors. need cast objects between java , python versions, you'll need if necessary, far needed primitive types easy cast, not sure if it's easy arbitrary java objects.
