Re: [Jython-users] Import/Use Jython class and method in Java

[Pierre T. <pie...@gm...>]

Hi,

I don't see enough of your code to comment a lot.

But as the code book said, your Java class is a façade doing the casting
like this:

public BuildingType create (String name, String location, String id) {

        PyObject buildingObject = buildingClass.__call__(new PyString(name),
                                                         new PyString(location),
                                                         new PyString(id));
        return (BuildingType)buildingObject.__tojava__(BuildingType.class);
    }

Do you have something similar?
