PyhtonInterpreter所有导入均失败

Question

Im using jython 2.7.0 and everything is working except one thing: I cant import anything. I do the following:

PythonInterpreter.initialize(props, System.getProperties(), new String[]{script.getParams().toJSON(), script.getContext().toJSON()});
PythonInterpreter interpreter = new PythonInterpreter();

interpreter.execfile(script.getPath());
interpreter.exec("import sys");
interpreter.exec("import json");
interpreter.exec("import random");

PyObject answerEvent = interpreter.eval("json.loads(sys.argv[0])");
PyObject answerContext = interpreter.eval("json.loads(sys.argv[1])");
PyObject answerResult = interpreter.eval("json.dumps(handler(sys.argv[0], sys.argv[1]))");

System.out.println("=====================================================================");
System.out.println(answerEvent.toString());
System.out.println(answerContext.toString());
System.out.println(answerResult.toString());
System.out.println("=====================================================================");

And it really does not matter which import I run, I always get the error:

Exception in thread "main" Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named json

or

Import Error: No module named random

How do I get the imports working.

EDIT

Sorry, my information was not completely correct: import sys is working without a problem. The other two imports arent.

EDIT 2

I tried a recommended workaround described here in the last post but the result was the same.

Answer 1

Fixed with the following:

interpreter.exec("import sys");
interpreter.exec("sys.path.append('/usr/lib/python2.7')");
interpreter.exec("import random");
interpreter.exec("import json");

I needed to point to the lib folder of python 2.7 (But I still dont know why)
