I have installed Jython and it is working nicely apart from a string of warnings every time that I open Jython, to execute a .py file, or to open the interactive "cmd.exe" window. I see from a web search that other people have had similar problems before, but despite trying many things (mainly changes to jython.bat and the jython registry file) I still get the problem, and I think that it slows down the process each time that I launch Jython.
 
I am using Windows 2000 Pro, have the latest Java runtime j2re1.4.1_04.
 
I have added:
 
python.cachedir=D:\\Program Files\\Jython21\\cachedir
python.path=.;d:\\Program Files\\Jython21\\Lib; d:\\Program Files\\Python23\\Lib
 
to the registry file, but it does not help. The cachedir exists and I have write authority and Java/Jython must because there are new files in cachedir/packages.
 
jython.bat reads:
"D:\Program Files\Java\j2re1.4.1_04\bin\java.exe" "-Dpython.home=D:\Program Files\Jython21" -classpath "D:\Program Files\Jython21\jython.jar;%CLASSPATH%" org.python.util.jython %ARGS%
 
The warning messages are:
 
*sys-package-mgr*: processing modified jar, 'D:\Program Files\Java\j2re1.4.1_04\lib\sunrsasign.jar'
*sys-package-mgr*: can't write cache file for 'D:\Program Files\Java\j2re1.4.1_04\lib\sunrsasign.jar'

Thanks in advance for any suggestions.
