[0:26] <__init__> hello
[0:27] <__init__> anyone here?
[0:28] * lucian (~lucian@cpc3-benw9-2-0-cust344.gate.cable.virginmedia.com) has joined #jython
[0:30] <agronholm> __init__, sure
[0:30] <agronholm> just don't be so frickin' impatient
[0:31] <__init__> haha
[0:31] * lucian_ (~lucian@cpc3-benw9-2-0-cust344.gate.cable.virginmedia.com) Quit (Ping timeout: 276 seconds)
[0:31] <__init__> what's up?
[0:31] <agronholm> is there something in particular you wanted to ask?
[0:32] <__init__> yeah
[0:32] <agronholm> then ask
[0:32] <__init__> is there a way to pass a reference to java methods/classes
[0:32] <__init__> from python classes?
[0:32] <agronholm> from python classes to where?
[0:33] <__init__> for example, if i have an instance of a java class running
[0:34] <__init__> can I run a jython script that accesses variables in that instance of the java class?
[0:34] <agronholm> of course
[0:34] <__init__> what would I use?
[0:34] <__init__> get/set?
[0:34] <agronholm> depends on how you run jython
[0:35] <agronholm> do you have a PythonInterpreter?
[0:35] <__init__> yeah
[0:35] <__init__> I have Jython set up as a standalone jar
[0:35] <agronholm> well, there are at least two ways
[0:35] <__init__> which is linked in the ClassPath of my java project
[0:35] <agronholm> the simplest one is .exec() or .eval()
[0:36] <agronholm> if you want to instantiate the class in python, that's even simpler
[0:36] <agronholm> just import it and use it
[0:36] <__init__> right now
[0:36] <agronholm> or if the instance is stored in a public static field of a class, you can use that too
[0:36] <__init__> i'm doing an execfile()
[0:37] <__init__> on an py script stored somewhere else
[0:37] <agronholm> what arguments does that take
[0:37] <__init__> nothing
[0:37] <agronholm> then I suppose your options are a tad more limited
[0:38] <__init__> you see, I don't want to create a new instance of the Java class
[0:38] <agronholm> what does the application do?
[0:38] <__init__> haha
[0:38] <__init__> it is actually an IRC client
[0:38] <agronholm> I mean, I've never used execfile() myself
[0:39] <agronholm> I'm importing python modules to the interpreter
[0:39] <__init__> so the Java files handle the sockets, Swing draws the window, and the commands etc..
[0:40] <agronholm> so why not do everything from python code?
[0:40] <__init__> while Jython is to be used to automate additional tasks
[0:40] <__init__> dunno
[0:40] <agronholm> it's a lot simpler that way
[0:41] <__init__> maybe
[0:41] <__init__> but it already works in Java
[0:42] <__init__> and rewriting it in python might be more work
[0:42] <agronholm> couldn't you then try to just import the python code instead?
[0:42] <agronholm> I think .execfile() is ill suited to this
[0:43] <__init__> yeah
[0:43] <__init__> i'll look into that
[0:44] <agronholm> you can import modules with org.python.core.imp.load("my.python.module");
[0:44] <agronholm> this gives you a PyModule object (typecast needed)
[0:45] <agronholm> then you can invoke methods on it with .invoke()
[0:45] <agronholm> s/methods/functions/
[0:45] <agronholm> .__getattr__() is something I also use
[0:46] <__init__> ok
[0:46] <__init__> thanks for your help
[0:46] <__init__> I got to run now
[0:46] <__init__> bi
