[Jython-users] Embedding jython

[<Mat...@i2...>]

Hi all,

I recently discovered jython - I must say, very cool!

I'm trying to embed a jython interpreter within a java application, and I 
have most things working, but have a few questions:

1) With an embedded interpreter, do I still need the jython distribution 
directory in order for the scripts I run to have access to the standard 
lib (Lib\*.py)?
2) How do I add an instance of a Java object to the namespace I pass to 
the PythonInterpreter exec() method?
3) How do I programmatically define a python class (and instantiate it) 
and pass it to the interpreter as in (2) ?  By programmatically I mean 
calling a bunch of java methods and _not_ simply evaluating a string that 
has my python class.
4) W.r.t (2) and (3) what I'm really trying to do is delegate to a Java 
instance from a Python instance so I can default some of the arguments on 
some methods (i.e. make a nicer interface to my java internals for the 
script writers).  Any tips on how to do this?
5) I setup my own SecurityManager to deny exits so that scripts can't 
terminate my java process - anyone know of a better way to do this?
6) If no to (5), I wrap my script execution in a try/except block to catch 
my DenyExitSecurityException, thus enabling me to swallow the ugly stack 
trace when a script calls exit, however, this only works when the script 
calls the java System.exit(), with sys.exit() I still get the stack trace. 
 Any idea how to stop this before I go digging around in the code?

Any help appreciated, thanks,

Matt
