[Jython-users] accessing win32com.client from jython

[<Dan...@at...>]

Is there a way in which I can access win32 libraries 
from jython? 
CPython has a set of excellent containers for windws 
platform specific tools. Is there any way in which I can 
access these capabilities from Jython as a way of 
bridging Java and COM without.
Has anyone ever explored this?
I know that I could architect things such that I could 
use sockets to communicate from Java/Jython to Cpython-
hosting-COM, but that seems unecessarily cumbersome to 
me.
Anyone have another approach.

Thanks for any good suggestions.

Microsoft's JVM supports COM.  It is the only one that does, though.
Part of java's goal is to be portable.  As such it can't rely on the
underlying platform.  A major difference between Java and CPython is
that java takes the least common denominator approach, whereas CPython
(the docs) just warn you that your program won't be portable.

You could also use any other distributed object middleware to connect
Java/Jython to CPython to take advantage of stuff java doesn't let you
use.  For example: XML-RPC or CORBA.

I haven't explored this, but it seems you could use JNI to embed C python in the JVM, then invoke Python code in the CPython interpreter.

Python-In-Python, anyone?

Hello,

	You can use a Java/COM bridge of which there are several available.  Jacob
is a good open source one, JIntegra is a paying licence based one.  Both
work reasonably OK but you do need to know a bit about how COM works.

Sure, or you could use JNI to embed COM directly.  I haven't used ILU
but it certainly looks worth a try if you need or intend to use
something of that nature :
