[Jython-dev] Jython with Jrockit JVM

[Andy <an...@mi...>]

The Jrockit eval version I'm using provides
just 2 files: jrockit.exe and jvm.dll (the simpler,
the better, if you ask me).  jrockit.exe
replaces java.exe.

Running jython I get the following error:

Traceback (innermost last):
  File "d:\Program Files\jython-2.0\Lib\site.py", line 66, in ?
AttributeError: module 'sys' has no attribute 'modules'

To those knowledgeable perhaps you can tell
in an instant whether the culprit is Jrockit
or possibly something overlooked in Jython?

I think Jython and specifically running pybench 
under Jython would make for a pretty informative
real-world benchmark of the performance of the
different JVMs.

So far I've managed to get pybench.py under
Jython to run with Sun's JDK 1.3 and IBM's
JDK 1.3 (part of Websphere) and non-translated
jcode under Elate/AmigaSDK.  

Fastest is Sun with average of 50+ seconds,
then IBM at around 70-80 seconds and as
expected jcode is slowest at well above 100
seconds but then it should be translated to
observe the true power of Elate's Java
implementation.  However, translation failed
and i have to do some serious study both of
Jython and the Elate Java environment to get 
it to work.

Jython rocks! Keep up the good work.
