[Jython-users] Problems with Java/Jython subclassing

[Steinar R. E. <ste...@fi...>]

Hi

Can anyone please give me some guidance on this. I try to create a =
system where I use Java classes that are subclassed for prototyping in =
Jython. Within the rest of the Java code (after initialization) I would =
like to refer to standard Java classes rather than PyObject. Hence, I =
try to subclass a Java class in Python and later just use the Java class =
itself when calling methods.

Am I trying to do something that is not possible within the Jython =
framework, or is there away around it.

Java :
class MyClass
{
    void Method()

}

Jython :

def PyMyClass (MyClass):
    def Method()


Java (Factory class)
class MyClassFactory

    public MyClass createMyClass()
    {
        /*
            use PythonInterpreter to create
            PyObject instance of PyMyClass()
           =20
            This works fine. I can call methods here (with invoke)
        */=20
        MyClass p=3D(MyClass) myPyObject;=20
        // Why does this typecase fail (error on PyInstance) ?
        // I thought this cast would work since the PyMyClass object =
subclasses MyClass... ??
   =20
    }
   =20
