[Jython-users] Accessing an application from an embedded Jython console

[Boudewijn R. <bo...@re...>]

I've got the console working - even if I still have to hack Actions.py
to be able to switch back to strong security, so now I've started to
integrate my application interface in the console. However, this is a
first for me, and I'm not an experienced Java developer, so I wanted to
ask you all to look at my solution, and give criticism (like: this is
a hack! It's unsupported! Don't do it! ;-).

What I've done is this: 

All functionality to the core application goes via an adapter. There's
already a Swing gui, so that was easy.

I've added an extra parameter to the constructor of the console, where
I put the adapter object:

class Console (Object):
    def __init__(self, adapter=None, adapterName=""):
       "@sig public Console(Object adapter, java.lang.String adapterName)" 
        self.locals = {}
        if adapter!=None:
          self.locals[adapterName]=adapter       

I've given the signature Object, so I can reuse the console for other
adapters - this is the point where I'm not sure. I can access the
interface from the Jython prompt, that's true.

From Java I call it like this:

        Console console=new Console(managementGuiAdapter, "managementAdapter");
        JScrollPane pane=new JScrollPane(console.getTextPane());
        console.write("Tryllian AFC 1.5 Habitat Management Console\n" +
                      "Uses Jython technology.\n"
                     ,"output");
        console.capturePythonOutput();
        console.getTextPane().requestFocus();
        console.newInput();
        getContentPane().add(pane);

And everything seems nice - but is it, really?
