如何使用Jython将Java列表传递给Python函数？

Question

我试图将Java arraylist传递给Python函数。我正在犯错误

SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/GEO_DM] threw exception [Cant instantiate class: com.ppts.bean.TriggerLawSocietyServiceBean.] with root cause java.lang.IllegalArgumentException: 'ofArrayType' must be compatible with existing array type of [Lorg.python.core.PyObject; see java.lang.Class.getName().

请参见下面我的java代码：

 PythonInterpreter interpreter=new PythonInterpreter(); 
    PyList pyList=new PyList(new ArrayList<>());
    interpreter.execfile(getClass().getResourceAsStream("/com/ppts/propertiesfiles/sample_return_script.py"));
    PyObject function=interpreter.get("returnSample");
    PyObject result=function.__call__(new PyInteger(1),pyList,new PyDictionary());
    progress=(int) result.__tojava__(Integer.class);

请参阅我的python代码：

def returnSample(var, list, dict):
    print(var)
    b=1
    flag=True
    print(list[0])
    print(dict.keys())
    return b

请不要看到用python完成的逻辑。 帮我把Arraylist传递给python函数
