[Jython-dev] jython on the IBM mainframe

[<pi...@un...>]

Hi!

In the last weeks I tried out jython on the IBM Mainframe, the 
OS390 or z/OS platform. With IBM JDK 1.3.0 and IBM JDK 1.3.1 it 
seems to run without problems.

But the really exciting stuff comes in with the use of CORBA in this 
environment. I plugged in successfully 2 Orbs, the free JacORB 
and the commercial orbix2000 for JAVA.

This leads you to a very clean programing model in python and the 
full strength of CORBA on these exotic (don't forget problems like 
EBCDIC codepage, no standard compiler/linker for the native 
environment) but still very important platform .

I made some loadtesting (10 concurrent clients running 1000 
method calls with hetorogenous IDL structs from our real life 
projects).

Beside the unbeatable clear programing model, the performance, 
scalability and safety (thread, memory etc.) the results are an 
evidence for the strength of your approach with JYTHON.

If you are interested in details, please contact me. I am aware, that 
I have to do this bits for your great effort and work with jython.

Cheers, Pit.
